Cross Roller Slewing Ring Bearings Suppliers

Cross Roller Slewing Ring Bearings are also known as Cross Roller Slewing Bearings.

Cross cylindrical roller slewing ring bearings with single row, consisting of two rings, have compact structure, light weight, high manufacturing precision, small assembly clearance, and high requirements for installation precision. Rollers for 1:1 cross arrangement, can simultaneously withstand axial force, tilting moment and larger radial force, is widely used in lifting transportation, engineering machinery and military products.

Crossed roller slewing bearings can withstand large radial force, medium-sized axial force and tilting moment, can meet the small clearance or “zero” clearance requirements. Crossed roller slewing ring bearings structure and application and Four-point contact ball slewing ring bearings are basically the same, but the rolling body from the steel ball into the roller, rolling body and the inner and outer rings of the contact from the point of contact into line contact. As a result, the bearing capacity increases, but the wear and friction torque increase. Compared with the traditional four-point contact ball structure, it has the characteristics of small size, high precision, high rigidity, large bearing capacity and high damage resistance, and is commonly used in bucket wheel machines, overweight transportation machinery, port machinery, excavating machinery, park play machines, filling machines, construction and engineering machinery and other large-scale rotating devices.
