Tips For Slew Bearing Selection
For slew bearing selection, we only talk horizontal installation, if is vertical installation, please contact with our engineer before design.
There are single row type slew bearing, crossed roller slew bearing, double row slew bearing and triple row slew bearing, Based on our experience, here is our advice:
when the raceway center diameter is smaller than 1.8 meter, then the single row type slewing bearing is the preferred alternative, when the raceway center diameter is bigger than 1.8 meter, the triple row slew bearing is preferred one. Single row type ball bearing has bigger load capacity than crossed roller type and double row with different diameter ball type slew bearing when there is the same size structure. so we strongly advise to prefer our Q type single row four point contact ball slewing bearing.
