Four-point contact ball bearing is comprised of an outer ring and an inner ring in integral structure or split structure. The two split rings of bearings in split structure are bolted together before delivery. Usually cages or spacers can be found in four-point contact ball bearings. In addition, bearings in full-filled ball structure is used only for large loads, thereby the full-filled ball structure bearings features good loading capacity and larger friction, the latter may result in scratches on the contact balls.

Overview of Customized Size Four Point Contact Inner Tooth Slewing Bearings

LTZC's Four Point Contact Ball Slewing Bearings are designed to provide a robust solution for applications requiring precise and reliable rotation. Composed of an inner ring, outer ring, rolling elements, and isolation block, these bearings feature four-point contact between the steel balls and the arc raceway. This design allows them to handle combined axial loads, radial forces, and overturning moments simultaneously. The versatility of the bearing is enhanced by options for toothless, internal, or external ring gears, depending on the installation and operational requirements. For applications requiring higher speeds, a disc cage structure can also be employed. Common series include 0.11, 0.12, and 0.13, each designed to meet specific needs.
