Product Description

Four point contact bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.
The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. Due to the two-piece inner rings, a large number of balls can be accommodated. The halves of the inner ring are matched to the specific bearing and must not be interchanged with those of bearings of the same size. The outer ring with the ball and cage assembly can be fitted separately from the halves of the inner ring.
