BWK
BWK-MTE-145
MTE-145 is a external gear four point contact ball slewing bearing with a 5.709 in inner-ring bore, 12.286 in outer-ring outside diameter and 1.968 in overall assembly height. The ball raceway supports combined loads, while the external gear provides a pinion drive interface. Mounting holes secure the rings to the supporting structure.

Check axial load, radial load and overturning moment together, including duty cycle and mounting stiffness. Match the bolt circles, hole sizes and ring heights to the mating structure. Confirm seal configuration, material grade and lubrication requirements before ordering. Verify tooth count, diametral pitch, gear face width and permissible tooth load against the mating pinion. Install on flat, adequately stiff mounting surfaces. Follow the specified bolt tightening procedure and lubrication schedule. Do not use the limiting moment rating alone as a complete application approval.
