Forklift Truck Lift Oil Cylinder<\/h2>\n

The lift oil cylinder converts hydraulic pressure into the vertical force that raises the forks, the carriage, and the load from ground level to the top shelf of the warehouse rack. It is the single most heavily loaded cylinder on the forklift \u2014 absorbing the full weight of every pallet, every crate, and every container the machine handles, shift after shift, for 10,000+ operating hours. When this cylinder leaks, drifts, or fails, the forklift stops earning money.<\/p>\n

Korea Ever-Power manufactures forklift lift oil cylinders<\/a> for every mast configuration \u2014 simplex, duplex, triplex, and full-free-lift \u2014 in both standard catalogue and OEM custom formats. Whether you need a direct replacement for a 3-tonne warehouse forklift or a custom-engineered cylinder for a 25-tonne container handler, the same ISO 9001-certified production lines, the same premium seal options, and the same 100% pressure testing apply across every unit.<\/p>\n<\/section>\n

Three Lift Oil Cylinder Types \u2014 Choose by Mast Configuration<\/h2>\n

The type of lift oil cylinder you need is determined by your mast configuration and the function the cylinder serves within it. There are three distinct types, and they are not interchangeable.<\/p>\n

 <\/p>\n

\n
\n
TYPE A<\/div>\n

Main Lift Cylinder<\/h3>\n

The primary lift actuator that extends the mast rails. One or two per mast channel, running the full height of the outer rail. These cylinders have the longest stroke in the forklift system \u2014 typically 1,500 mm \u2014 and are single-acting (gravity return). When the mast reaches maximum height, these cylinders are at full extension, carrying the entire load plus the mast weight as a structural column.<\/p>\n

Standard: 5 models \u00b7 \u03a656\u2013\u03a660 \u00b7 1,500 mm stroke<\/div>\n<\/div>\n
\n
TYPE B<\/div>\n

Short Lift \/ Free-Lift Cylinder<\/h3>\n

The inner cylinder that provides free-lift travel \u2014 raising the forks inside the collapsed mast before the mast itself begins to extend. It has a shorter stroke (500\u2013900 mm) because it must fit within the collapsed inner rail. Includes an integrated chain sprocket for 2:1 stroke multiplication and a check valve for load holding. This is the 27-component architecture.<\/p>\n

Standard: 5 models \u00b7 \u03a675\u2013\u03a695 \u00b7 775\u2013800 mm stroke<\/div>\n<\/div>\n
\n
TYPE C<\/div>\n

Bare-Actuator Lift Cylinder<\/h3>\n

The minimalist 8-component design \u2014 housing, rod, seals, steel ball check valve, and nothing else. No sprocket, no oil pipe. Used as an aftermarket replacement where the mast already has external sheaves and plumbing, or for non-forklift lift applications (tables, platforms, farm equipment) where the chain drive is handled externally.<\/p>\n

OEM custom only \u00b7 Any bore up to ~\u03a680 \u00b7 Any stroke<\/div>\n<\/div>\n<\/div>\n<\/section>\n

How a Forklift Lift Oil Cylinder Works<\/h2>\n

\"types-of-hydraulic-cylinders-6\"<\/p>\n

The operating cycle is simple in principle and precise in execution. The hydraulic pump draws oil from the reservoir and pressurises it to the system working pressure (typically 16\u201321 MPa). The directional control valve routes this pressurised oil through a hose to the lift cylinder’s single port at the bore end. The oil enters the bore below the piston, pushing the piston upward. Because the rod is connected to the carriage (directly or via chain), the forks rise.<\/p>\n

When the operator returns the lever to neutral, the directional valve closes, and the check valve inside the cylinder traps the oil. The load stays at height \u2014 indefinitely, without any pump pressure. This is the “hold” phase, and it depends entirely on the check valve seal integrity and the piston seal bypass rate. The Korea Ever-Power drift specification is \u2264 25 mm of fork descent in 10 minutes under rated load.<\/p>\n

When the operator pushes the lever to lower, the directional valve opens a metered return path from the cylinder bore back to the reservoir. The load weight pushes the piston down, displacing oil back through the metering orifice. The orifice size controls the descent speed \u2014 smaller orifice means slower descent. The lowering speed is always controlled, never free-fall.<\/p>\n<\/section>\n

How to Identify Which Lift Oil Cylinder You Need<\/h2>\n

Ordering the wrong cylinder type is the most common mistake buyers make \u2014 a main lift cylinder cannot replace a short lift cylinder, and a 27-component cylinder is unnecessary where an 8-component bare actuator will do. Answer these four questions to identify the correct cylinder type for your application.<\/p>\n

\n
\n

Question 1: Does your mast have a free-lift function?<\/strong><\/p>\n

If the forks can rise without the mast rails extending, your mast has a free-lift function, and you need a short lift cylinder (Type B) for the free-lift stage in addition to the main lift cylinders (Type A) for the mast extension stage. If the mast rails begin extending immediately when the forks rise, you have a simplex or basic duplex mast and only need main lift cylinders (Type A).<\/p>\n<\/div>\n

\n

Question 2: Does the existing cylinder have a chain sprocket on top?<\/strong><\/p>\n

If yes, you need the 27-component architecture with integrated sprocket (Type B). If no, you need either a main lift cylinder (Type A \u2014 no sprocket, long stroke) or a bare actuator (Type C \u2014 no sprocket, shorter stroke, external sheave).<\/p>\n<\/div>\n

\n

Question 3: Is the stroke greater or less than 1,000 mm?<\/strong><\/p>\n

Greater than 1,000 mm \u2192 most likely a main lift cylinder (Type A). Less than 1,000 mm \u2192 most likely a short lift or bare actuator (Type B or C). Measure the stroke by fully extending the rod and measuring from the gland face to the rod end.<\/p>\n<\/div>\n

\n

Question 4: Do the bore and stroke match a standard model?<\/strong><\/p>\n

If your measurements match one of the 10 standard models (5 main lift + 5 short lift), order the catalogue product for the fastest delivery and lowest cost. If any dimension deviates, order through the OEM custom service \u2014 Korea Ever-Power will manufacture to your exact specification.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Manufacturing \u2014 From Raw Steel to Tested Cylinder<\/h2>\n

Every lift oil cylinder begins as cold-drawn seamless steel tube (DIN 2391 \/ EN 10305-1) and C45 chrome-plated rod stock. The tube is honed to a mirror-finish bore (Ra \u2264 0.4 \u03bcm), the rod is induction-hardened and chrome-plated (20\u201340 \u03bcm), the seals are installed in a dust-controlled assembly area, and the completed cylinder is proof-pressure tested at 1.5\u00d7 working pressure before packaging. The Korea Ever-Power facility operates over 300 sets of CNC equipment with a designed annual capacity of 1,200,000 cylinders across all product types.<\/p>\n

Forklift Lift Oil Cylinder \u2014 Frequently Asked Questions<\/h2>\n
\n
\n

The forks drift down slowly when holding a load \u2014 is this the lift oil cylinder?<\/h3>\n

Probably, but check two things first. First, verify the directional control valve is in exact neutral \u2014 even a slight offset allows oil to leak from the cylinder bore back to the tank, causing drift that looks like a cylinder problem but is actually a valve problem. Second, check the check valve inside the cylinder \u2014 contamination on the valve seat is the most common cause of lift drift and accounts for approximately 60% of drift complaints. If both the control valve and the check valve are clean and the cylinder still drifts beyond 25 mm in 10 minutes, the piston seal has internal bypass and the cylinder needs a seal kit replacement or rebuild.<\/p>\n<\/div>\n

\n

How long does a forklift lift oil cylinder last?<\/h3>\n

Under normal indoor warehouse conditions with regular hydraulic oil changes, a quality lift oil cylinder typically provides 8,000\u201312,000 operating hours before the rod seal begins to show visible weeping. At 2,000 hours per year (single shift), that is 4\u20136 years. At 4,000 hours per year (double shift), 2\u20133 years. The first maintenance is usually a seal kit replacement at the weeping stage \u2014 which can be done in the field in 2\u20134 hours \u2014 extending the cylinder’s life by another 4,000\u20136,000 hours. Full cylinder replacement (housing, rod, all internals) is typically needed at 15,000\u201320,000 hours when the bore surface roughness exceeds the seal’s compensation range.<\/p>\n<\/div>\n

\n

Can I replace just the seals instead of the whole cylinder?<\/h3>\n

Yes, if the bore surface and rod chrome are in good condition. Remove the cylinder from the mast, disassemble, inspect the bore (look for scoring, pitting, or corrosion), inspect the rod (look for chrome flaking, deep scratches, or rust pitting). If the surfaces are smooth and the chrome is intact, a seal kit replacement restores the cylinder to specification. If the bore is scored or the chrome is damaged, resealing will not fix the problem \u2014 the new seals will ride over the damaged surface and leak within weeks. In that case, the cylinder needs re-honing (bore) and re-chroming (rod), or full replacement.<\/p>\n<\/div>\n

\n

What hydraulic oil should I use in the forklift?<\/h3>\n

ISO VG 32 or ISO VG 46 hydraulic oil, depending on operating temperature. VG 32 for environments consistently below 25\u00b0C (cold storage, northern climates). VG 46 for environments above 25\u00b0C (warm climates, outdoor operation, tropical regions). Never mix oil grades. Change the oil and filter every 2,000 hours or annually, whichever comes first. Oil contamination \u2014 water ingress, particulate matter, and oxidation byproducts \u2014 is the single biggest factor in hydraulic cylinder<\/a> seal wear. Clean oil extends cylinder life; dirty oil shortens it.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

We run 14 forklifts in a beverage distribution warehouse. Had two lift cylinders go within a month \u2014 both leaking past the rod seal after about 9,000 hours. The OEM wanted $1,400 each and 6 weeks. Got both from Ever-Power for less than half that and they arrived in under 3 weeks. Our mechanic said the finish quality on the rod is actually better than the originals. Both trucks back in service, no issues after 5 months of double-shift operation.<\/p>\n<\/div>\n

Replaced the main lift cylinders on a TCM FD30 triplex mast. I sent photos and measurements because the original part number was worn off. Ever-Power’s engineer identified the correct spec within a day and even pointed out that my rod diameter measurement was slightly off \u2014 he was right, I had measured over a worn spot. That kind of attention to detail makes a difference. Cylinders fit perfectly.<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2606<\/div>\n

Good cylinder. We use it in a textile warehouse. The only reason for 4 stars is that the first sample had the wrong port thread \u2014 BSP instead of metric. To their credit, Ever-Power reshipped the correct version at their own cost and it arrived in 10 days. The replacement cylinder itself is working very well, no leak after 4 months. For future orders we will double-check the port spec on the drawing confirmation before production.<\/p>\n<\/div>\n

Third time ordering from Ever-Power. This time was a short lift cylinder for a Hangcha CPCD25 \u2014 needed the 27-component version with sprocket. Asked for Hallite seals because we had good experience with them on the tilt cylinders we ordered last year. Everything arrived exactly as specified. The sprocket tooth profile matched the original chain perfectly. Already planning our next order \u2014 two main lift cylinders for a Clark forklift that’s due for rebuild next quarter.<\/p>\n<\/div>\n

The lift oil cylinder is the vertical engine of every forklift. When the operator pulls the lift lever, hydraulic oil flows into this cylinder, and the forks go up.
