Bearing units (Diamond flange units and square flange units)

Since the bearing unit is sealed both on the top and bottom surfaces, it can have a longer service life when used in a wet or dusty environment.

Lighter and easier to handle than steel bearing units.

Diamond flange units and square flange units

1. Features

Sealed on both the front and back

Water infiltration will cause rust since regular bearing units are not sealed in the back. Since the bearing unit is sealed on both on the front and back, the unit can enjoy a longer service life.

Housing is rust-resistant

Rust will develop on the housing even if the bearing is lubricated. This rust can be a problem at food factories. Tsubaki bearing unit housings are made of reinforced engineering plastic to prevent rust and keep conditions clean.
