Product Description

Double row ball slewing ring bearing
1. Introduction of LYHY double row ball slewing bearings
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.
The double row ball slewing bearing has three seat-rings. The steel balls and the retainers may be directly arranged into the upper and lower racers. Two rows of steel balls with different diameters are fitted according to the force. Such open type fitting is extraordinary convenient, the loading angels at upper and lower races are 90° Which can carry both of the axial force and capsizing moment. When the radial force is larger than 1/10 of the axial force, the races should be newly designed.

2. Structure:
Double row ball slewing bearing has three different types:
Double row ball slewing bearing with no gear
Double row ball slewing bearing with external gear
Double row ball slewing bearing with internal gear



3. Features:
Double row ball slewing ring bearings have following features:
Larger dimension of axial and radial and compact structure.
