Describe Of Double-Row Ball Type Slewing Ring

The Double Row Ball type Slewing bearing has three races. The steel ball and the spacer block can be directly discharged into the upper and lower raceways. According to the force condition, two rows of steel balls with different diameters are arranged. This open assembly is very convenient, the upper and lower circular races have a bearing angle of 90° and can withstand large axial forces and tipping moments. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The double-row and different-diameter spherical slewing bearings have relatively large axial and radial dimensions and are structurally fastened. It is especially suitable for loading and unloading machines such as tower cranes and truck cranes that require medium and large diameters.

Parameter Of Double-Row Ball Type Slewing Ring

Slewing Drive

Slewing drives is a kind of gearbox, consisting of gear, slew ring bearings, housing, seals, and other components. It can safely hold radial and axial loads, as well as transmit a torque for rotating. Most of slew drives are worm drive gearbox.

SLEWING RING DRIVES AND BEARINGS

Slew drive also can be called slew drive gearbox. Most of our slewing ring drive is kind of worm gear reducer. And the slew ring bearing is a gear drive part.

The slewing drive is a full-cycle rotary reduction transmission mechanism integrated with a driving power source.

As the slew drive manufacturer, Fuyong is one of the China leading producers of slewing ring drives and bearings. With a wide range of dimensions and designs, our worm slew drives and slewing ring are popular around the world. The slew drives and slewing bearing widely used in engineering machinery, coal mining machinery, fire equipment, industrial robots, photovoltaic power trackers, aviation and military defense. We have 18 independent intellectual property rights patents, and has passed ISO9000:2008 quality management system certification and EU export CE certification, professional production, excellent quality.
