Crane bearing and the ship crane bearing technical characteristics comparison

  • Harbour mobile crane bearing.

The three row roller slewing bearing of port crane usually use internal or external toothing diameter 4 meters, to withstand overturning moment is very high.
  • Stacker reclaimer and rotary bearing

Slewing bearing stacker reclaimer used usually adopts ball column combined type, three rows ofroller type and cross roller type, diameter of 3 meters most super. 

  Because of the poor working environment, dust, this kind of bearing has high carrying capacity, long service life, good sealingperformance characteristics. Considering the design of seal, uses the double sealing, plus steel protection sealing solution.

LYHY bearings are used for the four point contact ball slewing bearing the ferris wheel.

Slewing bearing ship unloader with external teeth usually adopts three rows of rollers in structure,about 4-6 meters in diameter.
  • Engineering machinery rotary bearing

Rotary bearing the most widely used most, generally not more than 4 meters in diameter, structure based on four point contact ball.

Application of rotary bearing the most concise, also called slewing bearings, ball and roller are to.
  • Ladle Turntable Bearing


  • Shield machine bearing 
The slewing bearing the most top application. High safety, high reliability, high stability, high value.

Belongs to the military bearing, is not introduced, quality is the first.
