Single-row ball slewing ring

A single-row ball slewing bearing is a large-scale rolling bearing composed of an inner ring, an outer ring, a single row of steel balls, and a cage (or spacer). It achieves four-point contact through the rolling of the single row of steel balls within double-arc raceways, enabling it to simultaneously withstand axial forces, radial forces, and overturning moments.

What is single-row ball slewing bearings?

Single-row slewing bearings are lightweight slewing bearings with only a single row of rolling elements and raceways, featuring a simple and compact design. Their core function is to drive the rolling elements of the slewing bearing to rotate 360 degrees through friction with the raceways via a geared ring meshing with a drive gear, generating a combined load of axial torque, radial torque, and overturning moment. They are compact, lightweight, and suitable for medium- to low-load equipment. Based on the arrangement of the rolling elements, single-row slewing bearings can be divided into single-row four-point contact ball slewing bearings and single-row crossed roller slewing bearings.

Single-row ball slewing bearings applications:

Single-row slewing bearings withstand moderate loads and are suitable for small to medium load applications such as cranes, excavators, stacker-reclaimers, rotary tables, and mechanical rotary joints.

LTZC precision slewing ring

LTZC bearings are machined using ultra-precision grinding equipment with a 'three-grind, three-inspection' process, and are equipped with a precision roundness tester to accurately detect parameters such as inner/outer diameter tolerance, roundness, and runout, with a testing accuracy of 0.01μm. Each batch of products undergoes 100% inspection to meet the following accuracy levels, ensuring high-precision bearings for our customers.
