Main components：
1. Cylinder Barrel – Internal roller burnished, surface finish Ra0.4.
2. Piston Rod – Chrome-plated surface, precision ground, finish Ra0.4.
3. Piston and Its Seals
4. Guide Bush and Its Seals
5. Welded Base – Welded connection, long service life.
6. Rod End Clevis – Optional threaded ends (internal or external).
7. Spherical Bearing – Optionally available with self-lubricating bushings or other types.
8. Hydraulic Ports – Customizable upon request.
9. Grease Fitting – Used to inject lubricant into the spherical bearing.
Technical data:
1. Working Pressure:
· Rated working pressure: 16–31.5 MPa (160–315 bar)
· Maximum working pressure: 1.5 × rated pressure
2. Operating Temperature:
· Normal operation: -40°C to +80°C
· Special requirements needed if exceeding this range.
3. Hydraulic Ports:
· Counterbored port connections, sealed with gaskets.
4. Tolerances:
· Spherical bearings & self-lubricating bushings: ISO standard
· Journal tolerance for trunnion pins: f8
5. Hydraulic Fluid:
· Mineral-based oil, contamination level ≤ ISO-DIS 4406 16/13
· Other fluids require special notification.
6. Speed:
· Maximum piston speed: 0.6 m/s
· Higher speeds need special consideration.
7. Stroke Length:
· Maximum: 3000 mm
· For long-stroke cylinders, internal guide bushings may be required to reduce support loads on the piston and rod.
8. Piston Rod:
· Chrome-plated surface
· Materials: 45# steel, 304 stainless steel, 316 stainless steel
