A slewing bearing or slewing ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. Slewing bearing with External gear are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base. We produce different slewing bearing with external gear.

1.What’s kinds of teeth type for slewing bearing rings with external gear we often make?

Our company provided you with standard teeth, British standard teeth, stub teeth, helical teeth, worm gear, synchronous pulley and sprocket.

2.What’s the module of tooth for slewing bearing with external gear we often make?

For common standard metric model tooth and British standard DP1.75、DP2、DP2.5、DP3、DP3.5、DP4、DP5、DP6、DP8、DP16、DP5/7、DP3/4、DP4/5, we all can make.

The precision of tooth machining is 8 grade,9 grade,10 grade.

3.Tooth heat treatment of slewing bearing with external gears

Tooth heat treatment of slewing bearing with external gear includes tooth surface quenching, tooth surface &tooth root quenching and full tooth quenching.
