Single Row Four Point Contact Ball Slewing Ring（ Q Series）

Brand LYHGB
Product origin Luoyang
Delivery time 45 days
Supply capacity 4000 sets/ month

Single row four point contact ball slewing ring Q series is a standard model series in China. Q means single row ball type. QW is external gear type, QN is internal gear type, QU is non gear type. It is made of two seat rings. The balls and the raceway are with four points contact, via which the axial force, radial force and resultant moment is born simultaneously. Outer Diameter is from 360 mm to 4700mm.
Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc.
In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings.
This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.

Single Row Four Point Contact Ball Slewing Ring (Q Series)

slewing ring

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:
