High-Precision Inline Strain Wave Gearboxes

Strain wave technology allows for a higher gear ratio and efficiency in an inline form-factor. These gearboxes are designed to work with SureServo2 and SureStep motors.

• High gear ratios compared to similar-sized planetary gearboxes (up to 160:1 for stepper gearboxes and 200:1 for servo gearboxes)
• Low heat and noise generation
• Large selection of output shaft diameters
• Lifetime zero backlash
• Pre-lubricated for life

Precision Gearboxes for Servomotors

The PGA series of inline planetary gearboxes has a thread-in mounting style, along with a level of precision and torque capacity that is best in its class. The PGB series of right-angle planetary gear reducers offers similar technical specifications to the PGA series and provides an excellent solution when space and clearance requirements are limited. PGD series gearboxes with compact design and hub style output are ideal for equipment that requires high-speed, high-precision indexing movement. The LS Electric MSS series of high precision gear reducers are specifically designed to mate to LS Electric L7C & L7P series servo motors.

• Thread-in mounting style
• Best-in-class backlash
• Four gear ratios available (5:1, 10:1, 15:1, 25:1) additional gear ratios for PGD models (35:1 and 50:1)
• PGA, PGB and PGD series gearboxes easily mate to SureServo motors, mounting hardware is included
• MSS series gearboxes mate to LS Electric servo motors
• A range of gear ratios available
• Uncaged needle roller bearings for high rigidity and torque

Stepper Systems

SureStep^® is an open-loop stepping system that provides simple and accurate control of position and speed, and offers a low cost motion control solution with up to 1800 oz-in of torque. SureStep Integrated stepper motors have integral encoders that allow for closed-loop control.

Programmable logic controllers (PLCs) or other indexers and motion controllers act as a stepper motor controller to send step pulses and direction signals that are received by the Standard stepper drive to allow very precise motion control.

The Advanced stepper drives also accept pulse inputs, but they also can be commanded by an analog speed signal or by serial communication. The SureStep stepping system series includes:

• DIP-switch configurable microstepper drives
• Software configurable advanced microstepper drives
• Stepper motor power supplies
• Stepper motors (NEMA 17, 23, 34 frame sizes) in single and dual-shaft models
• New! ... Linear actuators with NEMA stepper motor and integrated lead screw
• Stepper system accessories include braking, regen, cables
• SM-PRO SureMotion Pro stepper drive configuration software available as a free download or on USB drive

Leadshine (R) stepper drives offer basic features and general-purpose performance. Leadshine drives work with all SureStep stepper motors to provide an even more cost-effective system.

Precision Gearboxes for Small NEMA Motors

The SureGear PGCN series is a great gearbox value for servo, stepper, and other motion control applications requiring a NEMA size input/output interface. Features include:

• Wide range of ratios (5, 10, 25, 50, and 100:1)
• Low backlash of 30 arc-min or less
• 20,000 hour service life
• Maintenance free; requires no additional lubrication
• NEMA sizes 17, 23, and 34
• Includes hardware for mounting to SureStep stepper motors
• Optional shaft bushings available for mounting to other motors

Linear Motion Slides and Actuators

Motor-ready linear actuators and sliding components turn rotary motion into linear motion, providing a variety of X-Y and X-Y-Z positioning system solutions. Options for mounting stepper or servo motors as well as a full selection of accessories are available to complete a linear motion system.

• Ball screw driven actuators - capable of high speeds and duty cycles
• Lead screw driven actuators - provide high performance for light or heavy loads at an economical price
• Belt driven actuators - provide simple, dependable motion along a longer axis
• Undriven linear slides - used in multi-axis systems and run parallel to a linear actuator of the same travel length, typically used to stabilize the X-axis
• XYZ gantry components in all four styles

Stepper Motor Linear Actuators

Stepper motor linear actuators are stepper motors that incorporate a lead screw as the rotor, which translates motor torque into linear thrust. These actuators are often used with undriven linear slides or linear shafts/linear supports.

• NEMA 17 and NEMA 23 frame units available in a range of lengths and lead screw pitches
• Up to 193 lbs of thrust and speeds up to 18 inches/second
• Extension cables and other accessories available

Drive Couplings

Drive couplings are used to couple the shafts of various mechanical devices and compensate for misalignment.

• Jaw / Spider Couplings
• Double Loop Couplings
• Oldham Couplings
• Beam-Style Servo Couplings
• High-gain servo couplings

Bore Reducers

For use in all SureMotion drive coupling hubs to reduce bore size.

• Split-collar design with 2 set screw flats will not mark shaft
• 25% greater holding power than standard split collar
• Hardened stainless steel
