Crossed Cylindrical Roller Slewing Bearings (Internal Gears)

PMK Crossed Cylindrical Roller Slewing Bearings with Internal Gear provide integrated rotational transmission and load support in a compact assembly. The crossed roller arrangement ensures high rigidity and uniform load distribution while the internal gear enables efficient drive integration.

Key benefits

Combines load-bearing function and internal gear drive.
Compact, high-rigidity structure for limited space systems.
High positioning accuracy and smooth motion.
Low friction operation with precise gear engagement.
Long service life under combined loading conditions.

Applications

Robotics and automated rotary platforms.
CNC rotary tables and machine tool indexing heads.
Aerospace and radar drive systems.
Industrial automation with integrated drive mechanisms.
