High Speed Double Row Slewing Ring Bearing Customized Durable Long Life

Slewing Ring Bearing

Slewing bearing is widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and equipment as well as high-precision radar machinery and missile launcher equipment on the large slewing device. At the same time, we can also design, develop and produce various special structure slewing bearing according to the specific requirements of users.

Our different diameter ball slewing bearing has three seats ring,the steel balls and the spaces may be directly arranged into upper and lower raceways.two rows of steel balls with different diameters are fitted according to the load.such open mode fiting features are very convenience.the load angles of both upper and lower race are90,which enable the bearingto bear large axial froce and the overturning moment.when the radial force is larger than1/10 of the axial force .the raceways should be especial designed. the axial dimension and radial dimension
of double-row ball slewing bearing are rather large,and the bearing construction is sturdy

Product Feature

  • Slewing bearing has four series: Four point contact ball bearings without teeth, outer teeth and inner teeth, double row angle contact ball bearing, cross cylindrical roller bearing, cross taper bearing and three row cylindrical roller compound bearing.
  • Four point contact ball bearings have higher static load capacity.
  • Cross cylinder roller bearing has high dynamic load capacity, the pre - interference of cross taper roller bearing can make the bearing more rigid and accurate.
  • Three rows of cylindrical roller combination bearing due to the increasing of bearing height capacity , a variety of forces are borne by different raceway, so the same force, the diameter of the bearing can be greatly reduced, so that the main engine more compact is a kind of slewing bearing with high capacity.

Slewing bearing is also called rotary bearing, some people also called it: rotary support, cyclotron support.English name: slewing bearing or slewing ring bearing, or turntable bearing. It is a large bearing that can bear combined load, It can bear large axial and radial loads and overturning moment at the same time. Slewing bearing generally has mounting hole, internal gear or external gear, lubricating oil hole and sealing device, so can make the design structure of the main engine compact, easy to guide, easy to maintain.
