Horizontal Rotary Table - THE STRONG SOLUTION


The HC series is a high torque, zero backlash gear roller cam rotary table preferred in CNC machine tools as the fourth axis or in automation. Its zero backlash, high torque, integrated hydraulic brake and zero maintenance make it one of the most popular products in CNC manufacturing and automation. Siemens and Bosch-Rexroth motors and drives are available.

The HC rotary table minimizes drive wear, keeping it virtually maintenance-free throughout its service life, and maintains its original precision.

HC500 Highlights

  • No backlash , the roller and the cam are driven by a double preloaded roller contact. No backlash in forward and reverse rotation, which greatly improves the ultra-precision and ultra-stable characteristics of the roller cam.
  • The roller drive reduces wear and has a long service life.
  • Highly rigid, integrated turret design. Multiple rollers engaged with the camshaft increase rigidity during transmission.
  • High transmission efficiency, high-speed operation without temperature rise, and minimal effects of temperature fluctuations.
  • Durable. Maintenance free for long periods to maintain initial accuracy due to low wear, (3-5 years maintenance free).
  • Braking performance: Positioning during braking is kept within 0.002 mm. High precision machining is achieved. The brake is wear resistant and has a long service life.
