Feature:

Ball design is a simple design for low demanding applications and allows

? A better static capacity for oscillating movements

? A better resistance to structure deformations (clearance)

? A lower friction rate

Double row ball slewing bearing has three seat rings, 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 different diameter are fitted according to the stress condition. This kind of open assembly 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 suitable for the medium diameter tower cranes, truck mounted cranes, loading and unloading machinery etc..
# Note:

1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple& acute;s location can be change according to the user& acute;s application.

2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.

3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the max one.

4. & quot;K& quot; is the trim top coefficient,outer tooth 0.1,inner tooth 0.2
# Availability
