Oiles 500SP1-SL4 - High-strength brass bearings with embedded solid lubricant

The Oiles 500 SP1-SL4 series are designed as self-lubricating bearings which are made of high strength brass alloy bases cast along with innovative casting technology and engrained solid lubricants. Depending on the application, they can be combined with various types of solid lubricants

Features

Lubrication is not required for service.
create reciprocating motions, oscillations, repeated starts and stops, and so on.
Outstanding chemical and corrosion resistance.
Standard items come in a variety of sizes.
Shows excellent performance in both high-load and low-speed situations.
Shows higher wear resistance in applications where an oil film is rarely present.
