PBC Linear Core Competencies

Bonding polymer and fluoropolymer bearing material to metals

Developed and refined over the years, linear plain bearings excel where traditional ball bearings fail.

  • No moving parts eliminates risk of catastrophic failure 
  • Temperature extremes (-400°F to +400°F) 
  • 20x shock loads of similar ball bearing 
  • Self-lubricated, no maintenance 
  • Both linear and rotary applications 

Constant Force™ lead screw and thread rolling

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.

  • Uniform pressure applied to nut for life 
  • Consistent precision at all stages of motion profile 
  • Optimized thread geometries 
  • Superior lead accuracy 

Highly accurate length rails with SIMO® process

The Simultaneous Integral Milling Operation (SIMO) qualifies the rail to tolerances that have 6x less bow, 2x less twist, and 2x better flatness.

  • Parallelism +/- 0.001" 
  • Straightness +/- 0.002"/ft 
  • Twist < 0.25 degree/ft 
  • 20 ft sections join-able to achieve greater lengths 

Joining aluminum and steel together for longer rails

IVT rails are produced by mechanically embedding R"C" 58–62 hardened 420 stainless steel angle races onto an anodized aluminum profile.

  • Precise, durable, and lightweight 
  • Raceway to raceway +/- 0.001" 
  • Raceway to surface +/- 0.002" 

Applications

Actuators

Lead Screw Motors and Hybrid Linear Actuators

The patent pending Constant Force Lead Screw applies uniform pressure to the nut at all stages of travel along our quality CNC rolled lead screws. World class NEMA motors combined with an integrated lead screw make for one of the most accurate lead screw assemblies on the market. 

Key Features:

  • Superior Performance: 2-4x less backlash over the life of the device, as validated by leading lab automation customer testing 
  • Self-lubricating: All nut styles offered are self-lubricating for the life of the nut 
  • CNC Roll Threading: Allows for standard accuracies of 0.003"/ft. (2-3 times better than the competition). Precision lead accuracy of 0.001"/ft is available upon request 
  • 300 series stainless steel screw 
  • Optional PTFE coating lowers friction and increases efficiency 
  • Machined journals available to suit application requirements
