Excavator Seal Kit Describe
 

HBY is a high-performance buffer seal, it can be an ordinary PTFE buffer seals groove size interchange. The seals are made of polyurethane for valve use to avoid excessive pressure between the buffer ring and the rod seals. The installation of polyformaldehyde baffle ring can provide maximum extrusion resistance under vibration pressure load.

HBY Piston Seal, also known as the buffer seal ring, consists of a soft beige polyurethane seal and a hard black PA anti-extrusion ring added to the heel of the seal. In addition, HBY Piston Seal is used in conjunction with piston rod seals to absorb shock and fluctuating pressures under high loads, to isolate high-temperature liquids, and to improve seal durability.

Features
 
Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.
Compared PU with plastic, polyurethane not only offers excellent impact resistance, but also offers excellent wear resistant and high tensile strength. Polyurethane have subsituted metals in sleeve bearings, wear plates, conveyor rollers, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements.

Excellent durability and flexibility in using.
Excellent in resistance against heat,oil and wear.
Show stable in high speed rotation.
Resistant to heat, oil, fatigue, aging and friction due to excellent and special frame .
Large power, high speed, long service life, small distortion, less space occupy

Application
 

Cushion the impact pressure generated by the piston rod side of the hydraulic cylinder and relieve the back pressure
Prevent the oil temperature from directly overheating to the seal, resulting in the deterioration of the seal, play a cushioning, slightly cooling effect.
Reduce the frictional resistance of the piston rod seal and the problem of sliding and heating of the seal during the cylinder movement.

HBY Piston Rod Seal, also known as the buffer seal ring, consists of a soft beige polyurethane seal and a hard black PA anti-extrusion ring added to the heel of the seal. In addition, HBY Piston Seal is used in conjunction with piston rod seals to absorb shock and fluctuating pressures under high loads, to isolate high-temperature liquids, and to improve seal durability.
