Four Point Contact Ball Slewing Bearing (No Gear)

PMK Four Point Contact Ball Slewing Bearings (No Gear) are designed to carry combined axial, radial, and moment loads within a minimal structural envelope. The four-point contact design allows bidirectional axial load support and smooth rotation under light torque.

Key benefits

Compact structure with high axial and radial load capacity.
Smooth, low-torque rotation and precise motion.
Four-point ball contact provides bidirectional thrust support.
Lightweight design suitable for precision applications.
Maintenance-free operation with sealed or greased options.

Applications

Robotics and automation systems.
Light-duty rotary tables and manipulators.
Medical and optical instruments.
Packaging and positioning equipment.
