400 Series Profile Rail Linear Guides

400 Series Profile Rail Linear Guides

The 400 Series Profile Rail Linear Guide is the newest addition to the Thomson Linear Guide product line. The 400 Series is a cost effective, transport grade Profile Rail solution for cost-sensitive applications and is designed as a drop-in replacement with industry-standard envelope and hole patterns. Caged and non-caged carriages utilize the same rail design, enabling efficient use of inventory since only one rail type needs to be stocked for either carriage type.

  • Optional corrosion-resistant, hard chrome plating
  • Additional rubber wiper and metal scraper accessories
