Product Overview
Fleet operators find the 22/5142046 compelling: premium specs at aftermarket pricing. The 50mm ?? 22mm combination physically interchanges with dozens of OEM part numbers while potentially exceeding their original performance. The balanced 50mm/22mm geometry optimizes extend/retract force differentials.
Ever-power offers comprehensive technical support including system sizing calculations, failure mode analysis, and on-site troubleshooting for qualified OEM partners. Application engineering services are available at no charge for orders exceeding 50 units annually.
Key Features
Precision-Honed Barrel
The 50mm bore receives precision honing to H8 tolerance with cross-hatch surface pattern. This optimizes lubricant film retention and minimizes seal wear during high-cycle steering operations in demanding warehouse and distribution environments where reliability directly impacts operational uptime.
Hard Chrome Rod
The 22mm rod carries ??20??m hard chrome plating achieving HV 900+ surface hardness. This resists corrosion and abrasion from airborne contaminants, cleaning chemicals, and temperature fluctuations common in industrial material handling operations worldwide.
Triple-Barrier Seals
Three-stage architecture employs PTFE-bronze wiper to exclude contamination, polyurethane U-cup for dynamic pressure sealing, and NBR O-ring for static gland sealing. This combination delivers bidirectional leak-free performance across temperature extremes from -30??C to +100??C.
Full Pressure Testing
Every production unit undergoes hydrostatic testing at 1.5?? working pressure with minimum 60-second hold time and zero leakage acceptance criteria. Test pressure and duration exceed ISO 10771 requirements for hydraulic fluid power cylinders.
This demonstrates why Ever-power is preferred for single acting hydraulic cylinder among fleet operators.

Working Principle
The 22/5142046 operates as a double-acting linear actuator. During extension, pressurized fluid enters the cap-end port acting on the full 50mm bore area. The resulting force extends the 22mm rod to 199mm stroke. During retraction, fluid shifts to the rod-end port; the annular area generates pull force against return loads. A meter-out valve regulates speed while the relief valve limits pressure.
Applications
The 22/5142046 is purpose-built for forklift steering systems where precise angular control and rapid response are non-negotiable. Its 50mm 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 50mm ?? 22mm ?? 199mm unit with 358mm 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 358mm ??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 50mm 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 50mm 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 50mm bore. The 22mm 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.
