Rulon®LR | Superior Chemical Resistance

Rulon LR

Among the most popular variations of Rulon, Rulon LR is the “Go-To” material for general purpose bearing applications.

Rulon LR has a superior chemical inertness, with a ceramic filler for better dielectric and thermal insulation.

我们的客户依赖Rulon LR的耐久性和德pendability for high-pressure gaskets, slide pads, compressor components, and light-to-medium duty structural applications. And sleeve bearings made of Rulon LR can operate up to 10,000 PV, or even higher with intermittent service.

Rulon LR gives the best chemical resistance for mild-to-hardened steel shafting and couterfaces.
