Inline
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 inline models provide an output shaft inline and co-axial to the input (motor) shaft.
Right Angle
The SureGear PGB series of high-precision right angle servo gear reducers is an excellent choice for applications that require a more compact footprint.
- The PGB right-angle planetary gear reducers offer similar technical specifications to the PGA series inline gear reducers, and provides the customer with an excellent solution when space and clearance requirements are limited.
- Offered with a six arc-min backlash rating for 2-stage and nine arc-min backlash for 3-stage, the SureGear PGB series performs to OEMs' demanding expectations.
Inline with Hub Style Output
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.
