Product Description

double-row ball slewing ring

The double-row ball slewing ring has three seat-rings.The steel balls and the spacers may bedirectly arranged into the upper and lower raceways.Tow rows of steel balls with different diameters are fitted according to the load.This open mode fitting features extraordinary convence.The load anglesof both upper and lowerraces are 90o,which enable the bearing to bear large axial force and the resutant moment.When the radial force is larger than 1/10 of the axial force the raceways should be especiallydesigned.As the axial and radial dimension of the double-row ball slewing rings are rather large,the bearing construction is sturdy,hence it is especially suitable for tower cranes which requiring working diameter over medium range,mobile cranes and loding and unloading machines.

We manufacture all kinds of slewing bearings ranging from diameter 400 to 6,000mm. Internal gears, external gears and non-gears are available.

Slewing Ringss have a high load carrying capacity, a versatile range of applications and are highly cost-effective. Due to their design, a single bearing can reliably support radial, axial and tilting moment loads. It is therefore possible in many cases to replace bearing arrangements comprising a combination of radial and axial bearings by a single bearing.

This reduces, in some cases considerably, the costs and work required in the design of the adjacent construction and the fitting of bearings. It is made up of mounting holes, inner gear or outer gear, grease hole and sealing device. It has many positive characteristics; compact structure, light weight, good rigidity, steady speed and high precision
