Bearing Construction
The bearing consists of a self-lubricating woven Teflon® fiber and polyester liner supported by a filament wound continuous fiberglass fiber and epoxy resin matrix.
Size range
Consult a Rexnord engineer.
Bore shapes
Helical hex and threaded.
Load Capacity
Consult a Rexnord engineer.
Motion
The bearings convert linear motion to rotary motion and rotary motion to linear motion.
Friction
Duralon® bearings offer low-friction operation. Friction decreases with increasing load. Friction coefficients vary from .16 @500 psi to .07 @ 20,000 psi.
Self-lubricated
The bearing operates self-lubricated by Teflon® transfer to the shaft surface caused by relative movement between the shaft and bearing liner under load. Lubrication can be used if desired. Consult a Rexnord engineer for approved lubricants.
Electrical Properties
The Duralon® back-up material 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® materials 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. |
