As a trusted single acting hydraulic cylinder, Ever-power delivers actuators that meet OEM specifications for material handling.
Product Overview
Hydraulic designers specify Ever-power for the nan class because critical dimensions are tightly held. The 40mm bore uses plateau honing for optimal oil retention. The 20mm rod chrome is porosity-tested per ASTM B456. The substantial 40mm bore handles large-capacity forklifts and container handlers.
Environmental considerations are addressed through RoHS-compliant materials, recyclable packaging, and a cylinder exchange program that remanufactures returned units at 40% of replacement cost. This circular approach reduces waste while maintaining OEM-equivalent performance and warranty coverage.
Key Features
Seamless Construction
Machined from 27SiMn seamless alloy tubing, the 40mm barrel eliminates the stress riser inherent in welded pipe construction. This provides superior fatigue resistance through millions of steering cycles under varying pressure amplitudes and directional loading conditions.
Micro-Finished Rod
The 20mm piston rod is centerless ground to Ra 0.4??m before hard chrome plating. This surface finish ensures concentric operation that extends seal life by reducing lip wear, friction heat generation, and breakout pressure during steering corrections.
Temperature Resilience
Nitrile primary seals maintain elastomeric properties from -30??C to +100??C standard operating range. Viton compound upgrades are available for continuous operation above 80??C or for compatibility with synthetic hydraulic fluids and phosphate ester media.
Complete Traceability
Material certification with mill test reports accompanies every cylinder. Serialized batch codes etched on the barrel enable complete production history retrieval from raw steel billet through final inspection and pressure testing verification.
Ever-power industrial hydraulic cylinders expertise reduces downtime for demanding industrial applications.

Working Principle
The nan converts hydraulic power into linear steering motion. The pump sends flow through a priority valve ensuring the steering circuit receives volume even when lift and tilt demand simultaneously. Fluid enters the 40mm bore, displacing the piston. The 20mm chrome rod translates pressure through 164mm travel. On return, fluid exits to the reservoir via filter. Cushions decelerate the piston near stroke end.
Applications
In forklift steering, the nan replaces OEM cylinders on 1.5-ton to 5-ton capacity classes. The 40mm bore matches standard steering pump output ensuring compatible flow and pressure. Cold storage facilities value low-temperature seal performance where conventional units harden and leak. Port operations deploy this on reach stackers and straddle carriers where steering reliability directly impacts container throughput and vessel turnaround times.
Brand Compatibility
OEM-grade specifications ensure seamless integration with Hyster hydraulic systems at standard flow and pressure parameters. Rod end threads and gland dimensions match original components on Yale and Mitsubishi steer axles, eliminating adapter fittings. Technical datasheets with full dimensional drawings are available for engineering verification and BOM approval before purchase commitment.

How to Select the Right Hydraulic Cylinder
The selection process balances hydraulic system capability with mechanical constraints. Verify these parameters against equipment specs ?? bore 40mm, rod 20mm, stroke 164mm, mounting 368mm ?? considering duty cycle, fluid type, temperature range, and contamination exposure in your application.
- Calculate Forces
Extension: 25N. Retraction: 18N at 20 MPa. Verify these exceed application loads including safety margins for peak conditions. - Check Envelope Dimensions
Mounting 368mm, retracted 204mm, extended 368mm ?? verify against equipment clearances. Rod end must mate with steering linkage without modification. - Evaluate Environment
Temperature range, fluid type, duty cycle, contamination exposure determine seal selection and surface treatment for this 40mm bore cylinder in your specific conditions.
Structural Components
The 40mm barrel serves as pressure vessel and bearing housing ?? honed Ra 0.4??m eliminates separate liner need. End caps provide porting, mounting, and seal retention; torqued with anaerobic sealant against vibration loosening. The floating piston carries the polyurethane U-cup and two bronze-filled PTFE guide bands distributing side loads. The 20mm chrome rod exits through the head-end gland where triple-seal arrangement maintains zero leakage. Vent holes prevent pressure trapping behind the rod seal.
