Shanghai、NingboProduct Description
HGR Hydraulic Guide Ring is a guiding and supporting component designed for hydraulic cylinders and other reciprocating applications. It supports radial loads between moving components, maintains proper alignment, and prevents direct metal-to-metal contact between the piston, rod, and cylinder bore.
Available in phenolic fabric, POM, and filled PTFE, the HGR guide ring can be selected according to load capacity, operating conditions, temperature, and application requirements. The material options provide different levels of radial load resistance, making the guide ring suitable for applications ranging from heavy-duty hydraulic cylinders to lighter-load pneumatic and high-temperature systems.The split design allows the hydraulic cylinder guide ring to be installed quickly without special tools, while precise dimensions and tolerances help ensure stable guidance and reliable operation.
Technical Data
| Operating temperature | Surface speed | Working Pressure | |
| Phenolic Fabric | -50°C to +120°C | ≤ 0.5 m/s | ≤ 300 MPa |
| POM | -40°C to +100°C | ≤ 1 m/s | ≤ 120 MPa |
| PTFE | -100°C to +200°C | ≤ 5 m/s | ≤ 25 MPa |

Material Options
Phenolic fabric is suitable for high radial load applications and offers a static radial compressive strength of ≥300 MPa. It is recommended for hydraulic cylinders exposed to significant side loads, such as cylinders used in hydraulic supports and heavy-duty construction equipment.
POM provides a balanced combination of mechanical strength, wear resistance, and dimensional stability. With a static radial compressive strength of ≥120 MPa, it is suitable for applications with moderate radial loads, including telescopic and multi-stage cylinders.
Filled PTFE offers low friction and good sliding performance, making it suitable for light-load applications and environments where low friction or higher temperature resistance is required. Typical applications include pneumatic cylinders and certain high-temperature metallurgical hydraulic cylinders.
