  • Four-point contact ball bearings – two in one | Evolution

    Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported . The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two ...

  • Four point contact bearings for greater accuracy |

    2020-3-13 · FOUR-POINT CONTACT BALL BEARINGS The inner ring is split radially into two pieces. Their design allows one bearing to sustain significant axial loads in either direction. The contact angle is 35°, so the axial load capacity is high. This type is suitable for carrying pure axial loads or combined loads where the axial loads are high.
