Single row four point contact (series Q)

The same four-point contact design as our single-row four-point contact ball slewing ring (01 series) is more thinner and provides excellent torque, thrust and radial load capacity. Ideal for applications such as truck mounted cranes, cranes and non-precision industrial work benches etc.

Description

Provides excellent torque, thrust and radial load capacity. Ideal for applications such as truck mounted cranes, cranes and non-precision industrial work benches etc.

Note:

n1 is No. of lube holes, the user can specify the lube hole position.
n-φ can be changed to threading holes, hole diameter M, thread depth 2M.
There are standard products in the catalog, and the inner and outer diameters are random tolerances. If there is a locating requirement for slewing bearing, please indicate the site and tolerance.
It is standard type of our products, if you need more please contact with engineer.
