Double Row Ball Slewing Bearing

Double Row Ball Slewing Bearing

Increase the load capacity up to 80% compared to the same-sized single row ball slewing bearing

Double Row Ball Slewing Bearing

There are two kinds of double-row ball slewing bearings. One is with different ball diameters used in light weight application. The other one is eight-point contact bearings with two same ball raceways. You can simply think of it as two single-row ball bearings stacked together.

 

Just like single-row ball bearings, these double-row bearings can also handle axial, radial and tilting moment loads. However, due to the added row of balls, the load capacity of these bearings it typically 80% higher than the single-row version.

 

Having a higher load capacity, these double-row bearings are more suitable for. heavier duty applications such as tower cranes, truck-mounted cranes, tunnel boring machines, etc.

  • For mid-to-heavy load applications

  • Suitable for vibration conditions

  • Require less demanding mounting structure

  • Provide high load for a restricted installation space

  • Available in gearless, internally geared and externally gear versions

  • Available in induction hardened gears

  • Typical sizes range from 300mm-2000mm, with other sizes upon request.

  • Available with different corrosion protection coatings

  • Mating pinions are available for all slewing bearings.
