PGA Inline Series
The SureGear PGA series of high-precision servo gear reducers is an excellent choice for applications that require good accuracy and reliability at an exceptional value.
- This inline planetary gearbox has a thread-in mounting style, along with a level of precision and torque capacity that is best in its class.
- Offered in a concentric shaft design with a maximum seven arc-min backlash rating, the SureGear PGA series is an accurate, high performance, and cost effective solution for any OEM.
- The machining quality of the SureGear PGA helical planetary gears provides a very quiet and more efficient reducer than other competitive products that are similarly priced. SureGear PGA series planetary gearboxes easily mate to SureServo motors.
MSS Inline Series
The LS Electric MSS series of high precision gear reducers are specifically designed to mate to LS Electric L7C & L7P series servo motors. Everything you need to mount the gearbox to the LS Electric servo motor is included!
- 5:1, 10:1, and 20:1 gear ratios available for each servo motor (7.5kW systems limited to 15:1)
- Industry-standard mounting dimensions, and thread-in mounting style
- Very low backlash: 7 arc-min single stage (5:1 and 10:1 ratios), 9 arc-min for two-stage (15:1 and 20:1 ratios).
- IP65 Rated
- High efficiency, low noise
PGB Right Angle Series
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.
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.
