The function of the Bearing or wear ring is to guide the piston and piston rod of a hydraulic cylinder, as well as to withstand arising side loads. At the same time, it prevents any metal-to-metal contact, which will damage and score the surfaces and eventually cause seal damage, leakage and component damage.
Hallite offer bearings in various types of materials all of which offer high wear-resistance and demonstrate excellent friction properties. Our T63 polyacetal wear ring is suitable for both fluid and pneumatic cylinder applications, the T87bronze filled PTFE bearing is suitable for higher temperature applications. A glass filled nylon wear ring (T533) offers high bearing load capacity over a broad range of temperatures, whilst our high strength nylon bearing (T540) is suitable for telescopic applications. The T506, which is a woven fabric reinforced polyester resin bearing is available in three forms, cut rings, spiral lengths and flat coils, and is compatible with a wide range of fluids, and is used extensively in mining applications.
