Linear Shafting Support Rails

Linear Shafting Support Rails

Linear shafting eliminates binding caused by shaft deflection or sag in linear motion applications. Full-length shaft support rails also offer rigid, continuous support for higher loads in vertical or horizontal applications. Support rails can be end joined for longer continuous support. 


Key Features Across All Variations: 

  • Inch sizes of 1/2” to 3” and metric sizes 12mm to 50mm 
  • Lengths up to 144 inches 
  • End-joinable for longer travel lengths  
  • Cut to customer-specified length tolerances of:

LSG (Inch) Linear Steel Low Support Rail and Shaft Set

LSG (Inch) Linear Steel Low Support Rail and Shaft Set

Precision case hardened and ground shaft, plus a steel low support rail, effectively doubles the life of the shaft by allowing it to be turned over for a fresh surface when wear becomes evident. Both sides of the shaft are counterbored so the shaft may be rotated 180°, and rebolted for use on the new side. This guide is sold as a two-piece set; the shaft and support are not assembled. The guide is then bolted down through the top of the shaft to reduce installation time.

  • Available in sizes from 5/8” to 2”
  • Assemblies offered in continuous shaft lengths up to 180" with segmented support rails
