Wear Ring and hydraulic guide ring

Short Description:

Guide rings/wear ring have an important place in hydraulic and pneumatic systems.If there are radial loads in the system and no protections are provided, sealing elements do not also there may be permanent damage for the cylinder .Our guide ring (wear ring) could be produced with 3 different Materials.Wear rings guide pistons and piston rods in a hydraulic cylinder, minimizing transverse forces and preventing metal-to-metal contact. Use of wear rings reduces friction and optimizes the performance of piston and rod seals.

The function of the wear ring is to help keep the piston centered, which allows for even wear and pressure distribution on the seals. Popular wear ring materials include KasPex™ PEEK, glass filled nylon, bronze reinforced PTFE, glass reinforced PTF, and phenolic. Wear rings are used in both piston and rod applications. Wear rings are available in butt cut, angle cut, and step cut styles.

The function of a wear ring, wear band or guide ring is to absorb the side load forces of the rod and/or the piston and to prevent metal-to-metal contact that would otherwise damage and score the sliding surfaces and eventually cause seal damage, leakage and component failure. Wear rings should last longer than the seals as they are the only thing stopping expensive damage to the cylinder.

Our non-metallic wear rings for rod and piston applications offer great benefits over traditional metal guides:
*High load bearing capabilities
*Cost effective
*Easy installation and replacement
*Wear-resistant and long service life
*Low friction
*Wiping/cleaning effect
*Embedding of foreign particles possible
*Damping of mechanical vibrations
