Polyurethane Seal and Bushes

Application of this Polyurethane Bushing can be noticed in different vehicles, home appliances, mechanical system and construction accessories. This bushing is preferred over its rubber based counterpart for its better wear resistance capacity. Accessible in custom made specifications, this automobile accessory can endure severe working condition and is completely protected against abrasion, solvents, chemicals and high temperature. Flange shaped appearance, standard shrinkage rate, excellent compressive strength, praiseworthy bending strength, excellent elongation rate, long working life, water proof design, unique hardness level and required impact strength are its main attributes. We are a reliable exporter and manufacturer of standard grade Polyurethane Bushing.

Hydraulic systems are sealed using a combination of specialized seals. The main tasks of hydraulic seals are to retain hydraulic fluids, to exclude solid or liquid contamination, maintain rod and pistons alignment and to maintain the hydraulic pressure. In extreme cases seals need to withstand high pressures, extreme temperatures and transverse forces within the cylinder. Thus in application, the function of Hydraulic Seals goes far beyond preventing fluid leakage. Hydraulic piston seals prevent fluid from flowing across the cylinder head whereas the Rod seals prevent leakage of fluid from within the cylinder to the outside. This results in the pressure build up on either side of the piston, making the Cylinder extends or retracts in the opposite direction. The Sliding bearing or the Wear ring accommodates side loads, prevents metal-to-metal contact and maintain the concentricity of the hydraulic seals. The external wiper or Scraper prevents penetration of dirt and foreign liquid into the hydraulic system and helps in keeping the contamination level to a minimum. Hydraulic cylinders also require static sealing solutions including O-rings and most often back-up rings.
