– Double Row with brass or steel cage
– Straight or taper bore

When the bearing designed such that the circular arc center of the outer ring raceway matches with the bearing center, the bearing is self aligning, insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending.This type can accommodate radial load and axial load in both directions, which it especially suitable for applications in which heavy load or impact load is applied.The tapered bore type can be easily mounted/dismounted by using an adapter or withdrawal sleeve.

There are two types of tapered bores(Tapered Ratio) :

– 1:30 (supplementary code K30) —Suitable for series 240 and 241
– 1:12 (supplementary code K) — Suitable for series other than 240 and 241
