Double Row Different Diameter Ball Slewing Bearing

The double-row reducing ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower races. According to the stress conditions, two rows of steel balls with different diameters are arranged. Can bear axial force and radial force at the same time.

Range of external diameter: 300 mm to 10000 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

Lead Time: 30 days
