features & advantages
Determine which rotary table is the best fit for you.
ASK AN EXPERT
During table rotation 4 to 5 balls remain in constant contact with the cam shaft that creates a rigid configuration especially in no clamping operation.
HIGH TORQUE TRANSFER
Torque transfer efficiency is higher in a ball rolling mechanism as compared to the sliding mechanism of a worm gear. Generates 40% more drive torque.
Lifetime adjustment-free BALL DRIVE SYSTEM.
High accuracy machining with no backlash or reversal error. Enables shortening indexing and cycle times.
Index speeds up to 138.9 RPM.
Increased accuracy and repeatability specifications. Every revolution of the cam shaft produces highly precise results.
