Lubrication-free spherical polymer components replace metal bearings

Heavy dirt accumulation, dust and swarf are commonplace for pillow blocks and fixed flange bearings. 

Constant lubrication and maintenance are therefore necessary – this does not always have to be the case.

igus has developed lubrication-free alternatives using spherical components made of the high-performance plastic iglidur J, which can be fitted in a fabricated housing.

The use of polymers prevents dirt and dust from settling in pillow blocks and fixed flange bearings. 

The igubal spherical inserts are also suitable in agriculture and farming, in the food industry or in plant and general engineering applications. They can easily replace ball bearings in existing classic metallic pillow blocks and flange bearing housings. They are also available as an assembled bearing from stock mounted in a sheet metal housing.

The iglidur J material has a low coefficient of friction in dry operation – service life can be easily calculated online. 

As it absorbs only a little moisture, these plastic balls are suitable for outdoors applications. 

Due to the material’s chemical resistance, igubal components are also suitable for use in chemically demanding applications, such as agricultural equipment or even in glass processing.

All are available in three sizes for low-cost sheet metal housings (Ø 20mm, 25mm and 30 mm) as well as for cast housings (UC204-210).
