No Gear Four-point Contact Ball Slewing Bearing | High Precision Slewing Ring Bearings

Four-point Contact Ball Slewing Bearing (No Gear)

Four-point contact ball slewing bearings (no gear) are designed to handle high loads and provide precise rotational movement, but they do not include an integrated gear mechanism. These bearings are ideal for applications where an internal or external gear is not required or is separately integrated into the system. The bearing has four points of contact for each ball, which allows it to support axial, radial, and tilting moment loads effectively. This design helps distribute loads evenly and provides stability and precision. These models lack integrated gears, meaning the bearing itself does not include any internal or external gear mechanism. This design is suitable for applications where external gearing is used or where no gearing is needed. Balls are arranged in such a way to ensure smooth rotation and efficient load distribution. Four-point contact ball slewing bearings without integrated gears are essential for applications requiring high load capacity and precision, with the added flexibility of separate gear integration.
