igubal® pillow block bearings

igubal® pillow blockbearings are up to 40% more cost-effective and up to 80% lighter than comparable metal solutions. Their operation is also more economical, because they are lubrication-free and therefore maintenance-free. igubal® pillow block bearings have a high level of durability and stiffness – even when they are exposed to demanding ambient conditions over years. They are resistant to media, corrosion-free and function properly even in liquids and media. Even UV radiation from the sun, nuclear radiation and temperatures between -30 and +80°C do not have any negative impact on their running properties and their wear resistance. The pillow block bearings are additionally resistant to dust and dirt. The pillow block bearings  are available for shaft diameters from 5 to 50mm (tolerance: h6 to h9). The spherical balls provide automatic angle compensation. This enables the bearings to automatically equal out alignment errors and edge loads, misalignments and deflections of the shaft. In contrast to bearings made of metal, they are also able to absorb and dampen high-frequency vibrations.

Application areas

igubal® pillow block bearings ideally compensate for shaft misalignments, tilts and bends through their spherical adjustability. The main areas of use are therefore applications in which such effects cannot be prevented.

Tolerances

Maintenance-free igubal® pillow block bearings are designed with an inner diameter tolerance according to E10. The shaft tolerance should be between h6 and h9. The bearing clearance compensates for bearing expansion due to warming.

Assembly

igubal® pillow block bearings are designed for mounting with two screws. No exact bearing housing alignment is necessary, since the spherical bearing automatically compensates for alignment errors.

Product range

igubal® pillow block bearings are available in the K and E dimensional series for shaft diameters from 5 to 50mm. The K dimensional series is available in imperial dimensions. Contact us to request other dimensions.

What are the advantages of igubal® pillow block bearings?

In addition to our plastic solutions for pillow block and fixed flange bearings, you also have the option of using our plastic bearing inserts in existing metallic systems.

This guarantees maintenance-free and long-lasting operating times!

Pillow block bearings in a catamaran

Recreative Electric Vehicles, a shipyard in southern France, is building an electric catamaran that is 80% recyclable. Since weight is crucial, the company installed our lightweight plastic pillow block bearings, which require no maintenance or lubrication.
