Introduction

Welcome to CHG Bearing, your go-to source for high-quality Cross Roller Slewing Bearing. Whether you're in construction, lifting machinery, wind power generation, or any other industry requiring precision and durability, our slewing bearings are designed to meet your needs. In this comprehensive guide, we’ll explore what the products are, their benefits, applications, and more.

What is a Cross Roller Slewing Bearing?

A Cross Roller Slewing Bearing is a type of rotary bearing designed to handle large axial and radial loads, as well as moment loads. Unlike conventional slewing bearings, the slewing bearings feature rollers arranged in a crisscross pattern, which allows them to provide high precision and load-carrying capacity. This design reduces friction and increases the bearing's stability and lifespan.

Features
The Single-row Crossed Roller Slewing Bearing consists of two seating rings. It has compact structure, light weight, and high manufacturing accuracy. Due to the small assembly clearances, it has high requirements for the assembly accuracy. The rollers are 1:1 cross arranged. It can bear axial forces, turning moment and large radial forces at the same time.

Note:
1.n1 is the number of holes of lubricant, equally spaced, with oil cup M10×1 JB/T7940.1-JB/T7940.2
2.The fastening hole n-Φ can be replaced by the screw hole; the tooth width b can be changed to H-h
3.The peripheral force of the internal gear is the largest peripheral force; the rating peripheral force is the half of the peripheral force of the internal gear
4.The displacement coefficient of internal teeth is +0.35

Applications
It is applicable to the crane transportation, engineering machinery, military products, etc.
