Bearing Construction
Duralon mounted bearings consist of a Duralon composite insert mounted in a variety of housing configurations.
Size range
Standard sizes available from 1/2" to 2 3/16". Special inch sizes up to 26" also available. Metric sizes also available.
Bore shapes
Duralon® mounted units are available in cylindrical, hexagonal, and square bore configurations.
Housings
A wide variety of housings are available to choose from including flange and pillow block styles. Housing material options include polyamide or polypropelene, cast iron with a nickel plating option, and stainless steel.
Load Capacity
Consult with Rexnord for load and speed limitations.
Motion
The bearings work well in oscillatory, pivot, linear sliding and slow speed full rotation.
Friction
Duralon® bearings offer low-friction operation. Friction decreases with increasing load. Friction coefficients vary from .16 @500 psi to .05 @ 20,000 psi.
Self-lubricated
The bearing is constructed with woven Teflon® fiber. Teflon® is deposited on shaft surface during the start up phase and provides lubrication. Lubrication can be added if desired. Consult a Rexnord engineer for approved lubricants.
Electrical Properties
The Duralon bearing insert is an electrical insulator. Its dielectric strength is about 300 volts per mil. Since the back-up material is electrically non-conducting, electrolytic or galvanic action will not take place between it and the housing or the shaft.
Chemical Properties
Duralon® bearings are typically resistant to most chemicals. Due to the wide range of exposures, specific conditions must be checked. Consult a Rexnord engineer for specific chemicals. |
