Four Point Contact Ball Slewing Bearing (Internal Gear)

PMK Four Point Contact Ball Slewing Bearings with Internal Gear integrate precise load support and internal gear drive capability within a compact housing. The four-point contact geometry provides bidirectional axial load support while the internal gear enables compact drive integration for precision rotary mechanisms.

Key benefits

Integrated internal gear for compact drive systems.
Bidirectional axial load and moderate radial load capability.
High positioning accuracy and smooth motion.
Lightweight, space-saving construction.
Low friction and minimal backlash gear meshing.

Applications

CNC indexing tables and precision rotary actuators.
Light construction machinery and automation systems.
Robotics, packaging, and inspection systems.
Compact drive mechanisms requiring integrated gearing.
