Double row ball slewing bearing has three seat ring, the steel ball and the spacing block can be directly arrange into the upper and lower races, two rows of upper and lower steel balls with differently diameter are fitted according to the stress condition.This kind of open assemly is very convenient, for the upper and lower bear raceway arc angles is 90, which can bear large axial forces and tilting moment. When the radial force is greater than 0.1 times the axial force need to be specially designed the raceway.Double row different ball slewing bearing’s axial and radial size are relatively large and solid in structure, so it is specially fpr the medium diameter tower cranes,truck mounted cranes etc.loading and unloading machinery
Slewing bearing also known as slewing ring bearing,turntable bearing.It contain outer ring,
inner ring,rolling body,seals.The material of our products are generally high alloy-structural
steels ,such as 42CrMo 50Mn.The slewing bearing can work normally at a temperature of
-30℃ to +70℃,and we can design special type as customer need.
