Product Introduction                                        




1. Defination 

1) Slewing Bearing is a kind of comprehensive load which can be withstand the larger axial and radial load and tilting moment.

2) Standard : JB/2300-1999 and JB/2300-2011

3) Application: Widely used in Marine equipment, engineering machinery, light industry, machinery, metallurgical machinery, medical machinery, industrial machinery and other industries

2. Basic Structure

Slewing bearing is consisted of worm, slewing bearing, shell, motor and other components.Because core part USES the rotary bearing, can also carry axial force and radial force and Titing moment.

Single Row Crossed Roller slew bearing               

                                                               

                                                         Structure




    The single row crossed roller slewing bearing is composed of two seat rings, which design in compact
structure and light weight, the clearance is small when assembly, so need high precision. The roller are 1:1
cross arranged, it can bear the axial force, tilting moment and relatively large radial force. It is widely used
for hoisting, transportation, construction machinery, and the military products

Remark:


1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple's location can be
change according to the user's application.
2. n-fcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.
