Thomson Linear Motion Optmized
Profile Rail Bearings & Guides - 400 series
Product Details
The 400 Series is a 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.

- 45° double-faced ball track bearing arrangement
- Caged and non-caged carriages utilize the same rail design
- Polymer ball return system
- Standard end seals and longitudinal seals provide contaminant protection
- Lubrication channels direct grease to individual ball tracks

Caged ball option
The
caged ball option features balls encapsulated in a flexible polymer
chain that circulates around the ball track with the balls. Carriages
with the caged ball option utilize the same rail as the standard
carriage. Several advantages to using the caged ball are:
- Noise reduced by 6 dB
- Running smoothness increased by more than 30% over standard carriage
- Lubrication is better contained in ball circulation
