Crane Bearing

Crane bearing is used to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Generally, the bearing used for a crane can be the wheel group bearings, hook group bearings, pulley block bearings, reel group bearings, guide wheel sets bearing, anti-roller sets bearing, horizontal wheel sets bearing, and deflector sets bearing.

1. Application: Support the rotating parts of machinery.

2. There are two types: rolling bearing and sliding bearing. Rolling bearing has various standards and series, but its radial dimension, vibration and noise is bigger and its price is higher than the sliding bearing.

3. Rolling bearing is mainly constituted by outer ring, inner ring, rolling elements, bearing cage, seal and lubricant. Basing on the shape of rolling elements, rolling bearing is divided into two kinds: ball bearing and roller bearing.

4. Bearing function is to bear the radial load, or we can say it's to fix the shaft.
