Spherical insert bearings

Cost-effective & easy to assemble

Maintenance-free igubal® spherical insert bearings for metallic pillow block and fixed flange bearings. Due to their resistance to corrosion, dirt and dust, these spherical balls can increase the operating times of your applications: especially in dirty environments, the service life is up to eight times higher than with ball bearings.

Corrosion-free igubal® spherical insert bearings


Unlike metal, polymer spherical balls do not corrode and are suitable for use under water and in media.
