## Product Description

### Single Row Four Point Contact Ball Slewing Bearing (Q Series)

Explanation:

1. The dimensions of the No gear (QU) series are composed of Internal gear D and External gear dn with the same raceway center diameter, and The plug position and oil holes are arranged on the outer ring.

2. The plug position and oil holes are arranged on the outer ring.

A：Inner and outer rings are light holes.

B：The base of the inner and outer rings are threaded holes with a depth of T (the mounting hole T at the other end of the hole).

C：The base of outer rings is threaded holes with a depth of T, the inner ring is the light hole (the mounting hole T is at the other end of the hole).

D：The base of inner ring is threaded holes with a depth of T, the outer rings is the light hole (the mounting hole T is at the other end of the hole).

3. The External gear type (QW) structure diagram, the Internal gear type (QN) structure diagram and the No gear (QU) structure diagram are as follows:
