Preload mechanism

Rolling contact PreloadFeatures■ No backlash (play).
■ Power transferred by rolling contact
eliminates wear.
■ High accuracy and good efficiency.
■ Preloadable for high rigidity.

Low Maintenance and Excellent Price Performance
Consistent Long-term Accuracy without
Backlash Adjustment.

■ Worm gear models
Accuracy declines over time.Requires maintenance toachieve initial accuracy.

■ Worm gear models
Maintenance costs occur once or twice a year to adjust
the backlash.

■ The RollerDrive
Accuracy is consistent with no maintenance even after 5
million operation cycles.
(Requires regular oil changes)■ RollerDrive
Long-term use is possible without any mechanicalmaintenance.
Beats the cost of a worm gear even after adding annual
running costs to the initial investment cost. Price
performance continues thereafter.
Based on internal calculations.

Pressure setting: 0.02 MPa
Air consumption: 15L/min

Grinding Machine Applications■When used in grinding machines, the seal device on the outer

periphery of our table may become damaged. The warranty does
not cover any such damage.
Maximum Rotation Speed■The maximum rotation speed for the table given in the specifica-tions refers to the indexing speed. Consult with Sankyo if thetable is to be rotated continuously. Otherwise, the table will heatup and lose accuracy, causing overload alarms with the servomotor.
