Characteristics and performance

The 533 Piston bearing is molded with 33% heat stabilized, glass reinforced Nylon 66. The design of the 533T is a “t-shape” cross section which allows full bearing contact while also offering the advantage of a t-groove form of retention that does not require side land near the working surface of the wear band. The 533T is typically used in telescopic cylinder applications. It is not suitable for use in applications where water based fluids are used, nor is it suitable in applications where significant water is present, due to the swell of the nylon.
