​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The easy-to-use split 18K design is manufactured from a glass fiber-reinforced thermoplastic polyimide resin (heat stabilized nylon). These bearings reduce radial movement, helping to extend seal life. The exceptional physical properties and built-in lubricants make it suitable for use on rods, rams, or pistons in reciprocating, rotary, or static applications.​​​
