Feature: Four-point contact ball slewing bearings contact angle is usually 35°. If there is only a radial load, each steel ball contacts the raceway at four points. If there is only a unidirectional axial load, each steel ball contacts the raceway at two points. It can bear axial loads in two directions as well as a certain eccentric load, i.e. torque. Such kind of bearing has features and properties of both single-row and double-row angular contact ball bearings. If it is used in a high-speed scenario, two-point contact must be ensured for its normal working.
Material: 50Mn/42CrMo/S48C/42CrMo4/16Mn

Four point contact ball slewing bearings are designed to accommodate combined axial, radial, and tilting moment loads within a compact and efficient structure. Featuring a single row of balls with four-point contact geometry, this bearing type provides excellent load-carrying capacity in all load directions while maintaining smooth rotation and precise positioning.
