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


The new MS Miniature Linear Drive Systems utilize highly accurate profile linear guide ways integrated with Constant Force Technology lead screws and nuts to create an ideal solution in the smallest geometry possible. Using size 12 or 15 mm rails, the MS Systems maintain a low profile height of 13 mm or 16 mm. Available either with a knob for position applications or integrated with coupling, motor mount, and stepper or servo, these miniature systems are well suited for lab automation and bio sample handling.

Also available in miniature sizes are the MS Systems utilizing the self-lubricating plain bearing material FrelonGOLD®. The MR series rails are ideally suited to applications where no lubrication is an advantage and where severe contamination is present
