Features
■ 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.

Cost simulations are based on a table diameter of about 200 mm.
The RollerDrive graph is based on internal testing.(Center distance of test unit: 170)
■ Worm gear models
Accuracy declines over time.Requires maintenance to
achieve 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 mechanical
maintenance.
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.

Notes on Air Supply
Lubrication
■Sankyo's
■Sankyo's
CNC Circular Table comes standard equipped with an
air purge outlet. (Use it to blow out condensation and coolant to
prolong the life of electrical parts and prevent rust in the motor
housing.) Supply clean air for the air purge by referring to the
drawing shown below.
Pressure setting: 0.02 MPa
Air consumption: 15L/min
CNC Circular Table uses an oil bath to protect the
internal mechanisms and maintain reliability. Refill and perform
oil changes regularly using the oil listed in the instruction
manual.
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
Air combination
AC20C-01CG(SMC)
(Pressure Gauge G36-2-01)
maximum rotation speed for the table given in the specifications refers to the indexing speed. Consult with Sankyo if the
table is to be rotated continuously. Otherwise, the table will heat
up and lose accuracy, causing overload alarms with the servomotor.
