Large Diameter Single Row Ball Polymer Slewing Bearing with External Gear for Truck crane.some engineer puts forward a countermeasure in which a three-row roller slewing bearing replaces the original ball/roller combined slewing bearing, thereby greatly extending the slewing bearing's service life and guaranteeing the smooth running of the onsite equipment.



In its actual running often appears with some faults such as overload, abnormal impact, groove wear, noise, material properties, subsurface stresses. This paper mainly analyzes the causes of the faults from three aspects of the bearing's installation mode, its load condition, and its lubrication maintenance. So the solution is putted forward to improve the slewing bearing's accuracy.

Large Diameter Single Row Ball Polymer Slewing Bearing with External Gear for Truck crane.A computational procedure for calculation of Slewing Bearing Failure is presented. The calculation is based on the strain-life approach, and it takes into consideration depth-dependent material properties of the slewing bearing raceway.



Please check the weight of the ring to ensure slings and/or chains are of sufficient capacity! Shock loads, especially in the radial direction, must be avoided as this may damage the raceways.If stacked on a pallet then care must be taken not to dislodge seal strips or grease fittings during movement. Wooden or rubber spacers would be of benefit between each bearing. External gear teeth (especially) should be protected from any impact damage.Large Diameter Single Row Ball Polymer Slewing Bearing with External Gear for Truck crane.

Large Diameter Single Row Ball Polymer Slewing Bearing with External Gear for Truck crane.As supplied slewing rings are generally packed for storage in a covered store and for a period not exceeding 6 months. Light surface corrosion can usually be removed from exterior surfaces – and it is more important that the raceways are well greased and rust free. Standard commercial solvents can be used to degrease the slewing ring if necessary.

In extreme cases after long term storage bearings may need professionally reconditioning before installation.When unwrapping, care must be taken not to cut and damage the integral seals.
