What are oil free bushings and what are their features?

Plain bearings where the body of the bushing is saturated with lubricant and can be used 'without oil' or 'with a reduced oil supply'. Oil free bushings have the following features: 1. Low maintenance frequency; 2. Suitable for low speed and heavy load situations, compared with ball linear bearings; 3. Can also be used under harsh conditions of high temperature and low temperature; 4. Thinner and space saving, compared with linear bearings; 5. Can be used for both linear and rotational motions.

What are the materials and features of MISUMI oil free bushings?

MISUMI oil free bushings are available in 5 types, i.e. copper alloy, bronze casting, dry, resin, and casting. Copper alloy (metal type), excellent resistance to high temperature, chemicals and shock, suitable for heavy duty and low speed operation. Bronze casting (metal type) with excellent sinter resistance, enabling slight movements, suitable for low load and high speed operation. Dry type (composite layer type), high temperature resistant, suitable for heavy duty and low speed operation, thin-walled and compact. Resin (resin type), high temperature and chemical resistant (tetrafluoroethylene resin), complying with food sanitation law, suitable for low load and low speed operation. Castings (metal type), suitable for medium load and low speed operation.

What are the types of MISUMI oil-free bushings available?

There are straight type, shouldered type, thrust type, flange integrated type, flange type housing unit (built-in copper alloy bushing), and threaded sleeve type (built-in copper alloy bushing).
