Slewing Ring Identification

 identifying slewing rings can sometimes be hampered by part worn serial/part numbers or OEM only references. In order to help identify your slewing ring, we recommend the following:

1. Provide the machine model on which the bearing fits.

2.Provide a quick drawing giving with the following dimensions noted as accurately as possible.

2.1-Inner ring and outer ring diameters

2.2-Inner and outer flange diameters and heights

2.3-The height of the inner ring, outer ring and total assembled height

2.4The PCD of mounting holes in the inner and outer rings. Also note hole size, through or blind and or taped

2.5-Gear detail including number of teeth, approx tooth pitch, tooth height and depth + profile if possible.
