Inline Precision Servo Gearboxes with Hub Style Output
Need help selecting a Gearbox?
to configure and order.
High-precision planetary gearboxes for servo motors are mechanical power transmission components that drive a load at a reduced ratio of the motor speed. Output torque is increased; output power is unchanged (less efficiency losses). These hub-style inline models provide an output hub inline and co-axial to the input (motor) shaft.

PGD Hub Style Inline Series
The SureGear PGD series sets a new standard in applications requiring extremely high-torque ratings and rigidity.
The compact design and hub-style output is ideal for equipment that requires high-speed,
high-precision indexing movement.
The remarkable torsion stiffness and the low backlash of the planetary gearing combine to
provide outstanding positioning accuracy.
With a backlash rating less than 3 arc-minutes and exceptional torque handling capabilities,
the PGD series offers a high performance robust planetary solution for OEM customers.
The PGD reducer is often used for larger indexing applications and dial tables commonly found in
packaging and filling equipment and assembly automation systems.
Thread-in mounting style
Six gear ratios available (5:1, 10:1, 15:1, 25:1, 35:1, 50:1)
Mounting hardware is included for attaching to SureServo motors
Helical-cut planetary gears for quiet operation and reduced vibration
Uncaged needle roller bearings for high rigidity and torque
Adapter bushing connection for simple and effective attachment to most servo motors
High-viscosity, anti-separation grease does not migrate away from the gears; no leakage through the seal
Maintenance free: no need to replace the grease for the life of the unit
At nominal speed, service life is 20,000 hours
Can be positioned in any orientation
IP55 environmental rating
