Single Row Four Point Contact Ball (01) Internal Gear Mini Excavator Use Slewing Bearing

5 0 Reviews

Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.

Product Description

The slewing bearing of the small excavator basically needs to be replaced every two to three years. Most of the reasons are tooth ring gear collapse. Large radius of gyration, long-term high load, and overload work, causing tooth ring gear collapse. The slewing ring quality problems occupying a small part.

Xuzhou wanda slewing bearing co.,ltd is professional in produce varies slewing ring bearing for small excavators. The material for slewing bearing is quenched, and the tooth is hardened. If you have any demand, please contact us to get more details.
