Rulon® LR

Maroon material with low deformation characteristics



Rulon LR

Rulon® LR is a maroon colored bearing material best known for its versatile design properties.

It is compatible with most hardened steel substrates. Mild steel is acceptable; harder running surfaces are better.

Rulon® has a practically universal chemical inertness. Of the chemicals encountered in commercial practice, only molten sodium and fluorine, at elevated temperatures and pressures, show any signs of attack.

 

For continuous non-lubricated service, Rulon LR sleeve bearings are capable of operating up to 10,000 PV. Higher values are possible for intermittent service.

Use the Rulon Materials Selection Guide to compare various Rulon grades.
