Introduction to Bushings

Bushings are an extremely reliable, efficient, durable, and economical linear motion solution that can be used in an almost never ending list of applications. The format of bushings allows for it to be constructed in a large variety of shapes, sizes, and alternative designs.


Instead of using a profiled rail, linear bushings are a less expensive product that can be used in many different scenarios. Some examples are:

  • Self supporting guides that are only supported at the ends
  • Can be used on shafts rather than specific rails
  • Linear sets with iron, steel, or aluminum housings 
  • Commonly used in medical, food, and industrial industries
  • Applications under vacuum

Benefits of using Bushings

  • Maintenance-free guides 
    • Linear bushings don’t require much lubrication
    • Rugged and able to perform without damage
  • Corrosive environments
    • There are corrosion resistant bushing options
  • Functions in high temperature environments above 100 degree Celsius 
  • Linear Guides operate with low friction
