THOMSON - THOMSON 421N20ARL4000

The newest addition to the Thomson Linear Guide product line

Cost-effective, transport grade profile rail solution for cost-sensitive applications

A drop-in replacement with industry-standard envelope and hole patterns

Double-faced ball track bearing arrangements provide compliance during installation as well as equal load carrying capacity in all directions

Caged and non-caged carriages utilize the same rail design—enables efficient use of inventory, as only one rail type needs to be stocked for either carriage type

Polymer ball-return tube reduces noise while retaining lubrication

Standard double lip end and longitudinal seals retain lubrication while protecting the bearing from contamination (additional seals and scrapers available)

Channels direct lubricant to individual ball tracks to maximize lubrication effectiveness

Utilizes a 45°, face-to-face bearing arrangement, resulting in equal load-carrying capacity in all directions

Primary advantage of face-to-face configuration—rails are much more tolerant of mounting surface inaccuracies, enabling automation machine builders to reduce cost further by not having to prepare super-accurate mounting surfaces

Standard length for rails is 4,000 mm
