3. 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.
4. Material:50Mn/42CrMo/S48C/42CrMo4/16Mn

What is a Double Row Ball Slewing Bearing?

A Double Row Ball Slewing Bearing is a critical component in various types of machinery and equipment, known for its robustness and versatility. This bearing consists of two rows of balls separated by a raceway, providing high load capacity, durability, and smooth rotational movement. It’s commonly used in applications where both axial and radial loads are present, along with moments of force.
