Q series Single row ball slewing bearing

Structural characteristics, performance, and scope of application
The single-row four-point contact ball type slewing bearing consists of two races. It is compact in structure and light in weight. The steel ball is in contact with the arc track at four points. It can simultaneously support axial force, radial force and tilting moment. Conveyors, welding operators, small and medium-sized cranes and excavators can be used.

(1)Slewing bearing structure type Q: Single row ball type
(2)Transmission type code W: external gear type, N: internal tooth type, U: no tooth type
(3)Installation hole type code A: The inner and outer ring mounting holes are all through holes B: the inner and outer ring mounting holes are screw holes C: the outer ring mounting holes are screw holes, and the inner ring is the through hole D: outer ring The mounting hole is a through hole, and the inner ring is a screw hole
(4)Raceway diameter, mm
(5)rolling body diameter, mm
(6)Gear modulus classification code A: indicates large modulus, without A for small modulus
(7)Accuracy class classification G: Precision class, without G means ordinary class model marking example: Single row ball type, large modulus external teeth, outer ring screw hole inner ring through hole connection, raceway center diameter 1250mm, rolling element diameter 40mm, ordinary grade slewing bearing, the product model is marked as follows: Slewing bearing QWC1250.40A JG/T 66-1999

Note:
  1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10×1 JB/T7940.1-JB/T7940.
  2. The mounting hole n-Φ can be changed to the screw hole; the tooth width b can be changed to H-h.
  3. The circumferential force of the gear in the form is the maximum circumferential force, and the rated circumferential force is 1/2.
