Roller bearing slewing ring can be customized

51 Published by admin Jul 24,2024

Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

Our company specializes in producing single row ball type slewing bearings, double row ball type slewing bearings, three row roller type slewing bearings, single row cross roller type slewing bearings, etc, bal， roller size can be choice.Ball bearing, roller bearing slewing ring can be customized.

Roller bearing slewing ring generally has installation holes, internal or external gears, lubricating oil holes, and sealing devices, which can make the host design compact, easy to guide, and easy to maintain. There are four series of slewing bearing: four point contact ball bearings with or without teeth, external teeth and internal teeth, double row angular contact ball bearings, cross cylindrical roller bearings, cross tapered roller bearings, and three row cylindrical roller composite bearings.

Among them, the four point contact ball bearing has a high static load capacity, the crossed cylindrical roller has a high dynamic load capacity, and the pre interference of the crossed tapered roller bearing can make the bearing have a large support rigidity and rotation accuracy. The three row cylindrical roller combination bearing, due to the increase in bearing capacity, leads to the height of the bearing, and various forces are borne by different raceways. Therefore, under the same force situation, this roller bearing slewing ring diameter can be greatly reduced, making the main engine more compact. It is a high load-bearing capacity rotary bearing.

roller bearing slewing ring manufacturers

In general, the rolling elements of the slewing bearing are made of carbon chromium bearing steel that has been quenched as a whole. Made of GCr15 or GCr15SiMn steel; The roller bearing slewing ring is made of surface hardened steel. When the user has no special requirements, 50Mn steel is generally used for manufacturing. However, sometimes other grades of surface hardened steel such as 42CrMo, 5CrMnMo, etc. can be selected according to the specific usage conditions provided by the user to meet the needs of some special application hosts.
