The new Compact Series Linear Guide System from PBC Linear is designed to provide smooth, accurate, and repeatable linear motion in tight spaces. The Compact Series boasts a low profile—23 mm—standard system height making it an ideal solution for applications such as lab automation, medical, automated delivery systems, dispensing robotics, and electronic board manufacturing.

The Compact Series Linear Guide System can be configured—with standard options—to adapt to the demands of the application. Options include: two bearing choices, plain bearing or profile rail technology; lead screw with multiple leads; standard fixed or Constant Force™ anti-backlash nut; manual drive; integrated stepper or smart motor; and a motor mount option for use with other motors.

  • Bearing options: Plain bearing technology provides smooth and quiet operation. This choice is low cost, self-lubricating, and maintenance free. Profile rail technology provides rigid performance and is ideal for applications that require high loads or precise positional accuracy.

  • Lead Screw: 6 mm diameter lead screw is available in 1, 2, 5, and 10 mm leads.

  • Nut: Standard fixed or Constant Force™ anti-backlash nut.

  • Motor: Integrated NEMA 17 or NEMA 23 stepper motors; single, double, or triple stack; motor mount option for attaching stepper, servo, or smart motor, etc. Option with a manual hand knob is also available.


The SIMO® Series Linear Motion Platform is a family of solutions designed to put flexibility into the Design Engineer’s hands. This versatility to mix-n-match within the same design envelope allows an engineer to test or install multiple configurations, and gives them the ability to easily adapt to the changing requirements of load, speed, accuracy, rigidity, environment, and life. The SIMO® Series Linear Motion Platform can be configured and optimized for a single axis or combined to create a multi-axis XYZ system.

Rail Choices:

  • Low profile or tall version
  • Both qualified to +/- .001 with the patent pending SIMO® process

Tribology Choices:

  • Plain bearing - self-lubricating with FrelonGOLD®
  • V-Guide roller bearings for high speed applications
  • Profile rail linear guideways with recirculating ball bearings

Drive Choices:

  • Lead Screw
  • Ball Screw
  • Belt Drive


Constant Force Technology is an intuitive leap forward in nut design for lead screw applications. The result is greater consistency in performance, life, and a greater resistance to backlash. The patent pending self-adjusting anti-backlash feature utilizes a constant force spring to apply a uniform pressure to the nut at all stages of the motion profile.

In addition to Constant Force Technology, PBC Linear offers an adjustable coil spring nut. Both designs offer tremendous advantages over traditional torsion spring designs. Standard fixed nuts for a wide variety of applications are also available. Coated stainless steel screws are available in these sizes:

  • Diameters - 6, 10, 12, 16 mm
  • Leads - 1, 2, 4, 5, 6, 8, 10, 12, 16, 25 mm
