Thomson 400-Series ball profile linear guide bearing system

The range covers six nominal rail widths from 15mm to 45mm in stock lengths of 4000mm and a wide choice of carriage styles including narrow and extra-long variants to match application requirements. With individual carriage load capacity between 9kN and 130kN (approximately) and a choice of two accuracy and two preload grades for precision and load matching, notable features for the 400-series include a polymer-lined ball-return tube that reduces noise and vibration, and individual ball track lubricant channels that maximise lubrication effectiveness.

In addition, the range benefits from a very wide selection of options and accessories to optimise the performance and costs of the installed bearing system. These include a carriage with a caged ball-spacing retainer option for increased running smoothness and lower noise at high speeds, as well as a standard non-caged version for general-purpose use. While the standard build specification for all carriages includes double-lip end and longitudinal seals, additional rubber wipers and metal scrapers are available for increased durability in harsh environmental conditions. For improved corrosion resistance, hard-chrome plating is also available.
