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.
