PU Hydraulic Buffer Ring Seal Hby Type for Cylinder Piston Rod, Polyurethane Wear-Resistant Shock Absorber Ring (ISO 10766 Standard)
HBY type is special shaped slit at the sliding lip that can leak back pressure eliminates the pressure between the rod packing and buffer ring. It is used in combination with rod packing to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing.
The Hby Type Hydraulic Cylinder PU Buffer Ring Seal is engineered to protect piston rods and absorb shock in high-pressure hydraulic systems. Crafted from premium polyurethane (PU), this seal delivers exceptional wear resistance and durability, extending equipment lifespan while reducing maintenance costs.
Key Features
Ultimate Shock Absorption: Minimizes impact forces in hydraulic cylinders, preventing damage to rods and glands during operation
Superior Wear Resistance: PU material withstands abrasive particles and high loads (up to 25 MPa), offering 3x longer service life than rubber seals
Precision Compatibility: Complies with ISO 10766 standards for seamless integration into industrial cylinders and machinery
Multi-Environment Performance: Operates in temperatures from -40°C to +110°C, resistant to oils, hydraulic fluids, and UV exposure
Easy Installation: Split design allows quick replacement without disassembling hydraulic components
Technical Specifications
Material: Polyurethane (PU)
Hardness: 92A ±5 Shore A
Standards: ISO 10766, DIN 3770
Temperature Range: -40°C to +110°C
Pressure Rating: ≤25 MPa
Color: Black or Yellow (optional)
Applications
Hydraulic cylinder piston rods in excavators and cranes
Industrial press cushioning systems
Agricultural machinery shock absorption
Marine hydraulic actuators
Mining equipment cylinder protection
Performance Advantages
Reduces metal-to-metal contact by 90%, lowering equipment vibration and noise
Maintains elasticity in extreme temperatures for consistent sealing
Withstands 500,000+ cycles at 15 MPa dynamic pressure
Zero lubrication required due to self-lubricating properties
Customization Options
Non-standard sizes (inner diameter 10mm-500mm)
FDA-compliant grades for food processing equipment
Flame-retardant (UL 94 HB) and anti-static variants
Grooved or adhesive-backed versions for specific mounting
Note
For optimal performance, ensure gland dimensions match ISO 10766 specifications. Contact us for CAD drawings and technical support.
