Double-row Ball Slewing Ring Bearing
Double-row ball slewing ring with same diameter balls is usually used for wind driven generators and concrete pump trucks. In wind driven generator applications, double-row ball slewing ring is often installed at the bottom of propellers for variable pitch control which requires zero clearance, large start friction moment and high running accuracy.
With compact construction, the double-row ball slewing ring bearing decreases the diameter of mounting holes in the inner and outer ring and increases the loading capacity.
Double-row ball slewing ring bearing usually comprises 3 rings, steel balls and spacers can enter the upper and lower raceways directly. Two sets of steel ball are placed based on the force analysis. With such configuration, the 90° bearing angles of the upper and lower arc raceway enable the bearing to take large axial force and tilting moment. Special design is needed for the raceway when the radial force is greater than one tenth axial force
Slewing Bearing Details
Range of external diameter: 100 mm to 15000 mm
Ring material: 42CrMo / 50Mn/ C45
Ball/roller material: GCr15
Cage material: steel 20 or ZL102 cast aluminum alloy
Spacer material: nylon 6 / nylon 66
Quenching hardness of raceway: HRC55-62
Tooth type: no gear, internal gear, external gear
Advantages:
Double-row Angular Contact Ball Bearings can take axial load in eighter direction and are the equivalent of arranging two Single-row Angular Contact Bearings in a back-to-back configuration. These bearings are ideal if axial space is limited, as they take up less space compared to using two single row bearings
Application:
Double row contact ball slewing bearings are widely used for the following applications:
Excavator
Crawler crane
Port machinery
Amusement facilities
