Precision Slewing Bearing with Internal Gear

Crossed roller slewing bearing

Its crossed roller turntable bearing structure delivers high rigidity, superior load capacity and excellent rotaional accuracy, making it ideal for heavy-duty, high-speed, and high-repeat-precision machining applications, such as CNC milling machines, lathes, grinding machines and other precision machine tools requiring high-accuracy rotary motion.

Features & performance advantages

Internal ground gear: the inner ring's gear surface undergoes precision grinding, achieving high tooth profile accuracy and minimal meshing clearance.

Crossed roller design: optimized for high rigidity and load-bearing performance, enabling stable rotation under heavy loads and high speeds.

Robust construcion: made of high-strength alloy steel with anti-rust surface treatment, ensuring durability in industrial conditions.
