GEARING MATERIALS

___________________________________

 

High accuracy machining with no backlash or reversal error. Enables shortening indexing and cycle time.

 

 

HIGH SPEED

___________________________________

 

Index speeds up to 138.9 RPM.

 

 

HIGH ACCURACY

___________________________________

 

Increased accuracy and repeatability specifications. Every revolution of the cam shaft produces highly precise results.

HIGH RIGIDITY

___________________________________

 

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.

 

ZERO MAINTENANCE

___________________________________

 

Lifetime adjustment-free BALL DRIVE SYSTEM.
