Measurement of Four Ball Ball Bearings

Four penalty ball bearings

The four point bearing has two circular arc-shaped grooves on its inner and outer rings, and the curvature centers of these grooves are offset so that during radial loading, the ball contacts the grooves at four points. The contact angle of a four point bearing is relatively large (usually 35 °). Therefore, this type of bearing can transmit high axial loads in both directions.

The shape, radius, and surface roughness of the raceway are crucial for the operational performance and noise characteristics of such bearings. Taylor Hobson has many Form Talysurf inductance series instruments suitable for measuring the shape and surface roughness characteristics of four ball ball bearings.

In addition, the roundness and waviness of the channel and rolling components are also crucial. Usually, we use Talyrond roundness measuring instruments to measure these characteristics.
