Product description
Low-cost bearing inserts made of iglide® high-performance plastic with sheet metal flange bearing.
igubal® bearing inserts are a maintenance-free alternative to insert bearings in metal pillow block and flange bearings. Available for sheet metal housings in sizes P204-208.

The bearing inserts made of high-performance plastic allow dry running without external lubrication. Especially in environments with heavy contamination, the advantages are significant: While classic metal bearings often require relubrication, the igubal® bearing inserts have an embedded solid lubricant, which makes additional lubrication unnecessary. In addition, the JEM-SP bearing inserts are often more durable and are very wear-resistant even in very dirty environments.

Easy to mount
Mounting the bearing inserts is a breeze. They can be inserted by hand into metal plummer block and flanged bearing housings in seconds - without expensive and time-consuming conversions.
