Ever-power has established itself as a premier industrial hydraulic cylinders through consistent quality and responsive support.
Product Overview
The FT800.55A.012 optimizes the 80mm bore area and 32mm rod annulus relationship. This geometry produces predictable force in both extension and retraction, eliminating jerky motion. The multi-lip seal ?? PTFE-bronze wiper, PU U-cup, and nitrile O-ring ?? maintains leak-free operation from arctic cold to tropical yards. The substantial 80mm bore handles large-capacity forklifts and container handlers.
Maintenance intervals depend on duty cycle severity. Under normal warehouse conditions with clean fluid, inspect rod surface and wiper seal condition every 500 operating hours. Replace seal kit proactively at 4,000 hours to prevent unplanned downtime during critical operations.
Key Features
Balanced Force Geometry
The 80mm ?? 32mm bore-to-rod ratio is optimized to produce predictable push and pull force characteristics. This eliminates jerky steering response during rapid pressure transients when navigating tight warehouse aisles or maneuvering in congested loading dock areas.
Induction-Hardened Core
The 32mm rod core achieves HRC 28-32 through induction hardening prior to chrome deposition. This substrate hardness supports the chrome layer against denting from impact loads during dock operations, pothole traversal, and rough terrain encountered in outdoor yard applications.
Cleanroom Assembly
Pistons and seals are installed in a controlled environment maintaining particle counts below Class 1000 levels. This prevents airborne contamination from causing internal scoring of precision-honed surfaces and premature seal degradation during initial break-in period.
CMM Verification
Coordinate Measuring Machine inspection confirms all critical dimensions including bore diameter, rod concentricity, stroke length accuracy within ??0.5mm, and mounting hole positional tolerances before release from quality hold.
This demonstrates why Ever-power is preferred for custom hydraulic cylinders among fleet operators.

Working Principle
Through Pascal’s principle, pressurized oil from the gear pump enters the FT800.55A.012’s 80mm bore. At 16-21 MPa typical for forklifts, pressure acts on the piston face creating force proportional to the bore area. The 32mm rod emerges, pivoting the steering linkage through an arc from 200mm stroke and lever geometry. Reversing the wheel switches valve position, pressurizing the rod-side chamber. The differential area means extension force exceeds retraction force.
Applications
The FT800.55A.012 is purpose-built for forklift steering systems where precise angular control and rapid response are non-negotiable. Its 80mm bore generates torque to pivot steer wheels through full arc, even when stationary and loaded. Narrow-aisle warehouses benefit from consistent steering feel reducing operator fatigue during long shifts. The unit also suits AGVs where repeatability determines navigation accuracy along defined paths. Marine terminal operations and cold storage facilities particularly value the responsive steering and low-temperature seal performance.
Brand Compatibility
Engineered for interchangeability, this unit matches mounting envelope, port geometry, and force characteristics of factory cylinders on Mitsubishi material handling equipment. Pin-eye and clevis dimensions conform to OEM specifications used by TCM and Heli, allowing direct bolt-on replacement without adapters or bracket modifications. Aftermarket distributors stock this as a universal solution for Hangcha forklift families commonly found in rental and leasing fleets requiring rapid turnaround.

How to Select the Right Hydraulic Cylinder
Selecting a replacement cylinder involves evaluation of multiple interdependent parameters. Use this framework to confirm the 80mm ?? 32mm ?? 200mm unit with 535mm mounting suits your equipment. Each parameter affects performance, installation compatibility, and service life in your specific operating environment.
- Check Mounting Dimensions
Center-to-center between pins must match 535mm ??2mm. Verify pin diameter compatibility. Check hose and fitting clearance at full extension without interference. - Pressure Compatibility
Confirm system operates at ??25 MPa with this 80mm bore. Verify pump flow produces acceptable extension/retraction speed for your steering response requirements. - Specify Seal Material
Standard NBR suits mineral oil at -30??C to +100??C. Select Viton for synthetic fluids or temps above 100??C. Specify PU for water-glycol mixtures at order time.
Structural Components
The 80mm barrel is the largest structural element, thick-wall seamless steel containing 25 MPa with 4:1 safety factor. The cap-end houses the inlet port and rear mounting ?? pin-eye or clevis lug machined integrally. The piston incorporates seal grooves and wear bands centering it within the 80mm bore. The 32mm rod resists axial tension and compression; hard chrome seals against the gland and withstands environmental exposure. The threaded rod gland integrates sealing, bearing, and retention in a replaceable cartridge.
