xiros® pillow block ball bearings

The xiros® pillow block units from igus® are not only up to 60% lighter than metal ones but are also up to 40% more cost-effective. They allow lubrication-free, low-friction operation with a high standard of hygiene.

Resistance to corrosion and various media is a further advantage of polymer pillow block bearing units.

In addition to the fixed versions, pivoting pillow block units that compensate for misalignment are available.If required, these are also available as completely metal-free and at the same time non-magnetic solutions with glass balls.

A 1:1 replacement of metallic pillow block bearings is possible.

Available inner diameter of locking variants: 6, 10, 15, 17, 20, 25, 30mm
Available inner diameter of the pivoting variants: 8, 10, 12, 20, 25, 30mm
