Ewellix launches next generation miniature profile rail guides for industrial and medical automation

A new series of compact, precision linear rail guides from Ewellix for industrial and laboratory applications featuring long service life, low noise and low maintenance.

Ewellix, formerly SKF Motion Technologies, has launched a series of compact precision rail guides that are low noise, have precision accuracy and require minimal maintenance due to self-lubricating features for industrial and laboratory applications.

The all-stainless steel LLS Series includes a unique ball retention plate at the bottom of the carriage for additional robustness as well as a ball recirculation system that facilitates easy and secure carriage mounting by ensuring that the balls are retained in place during assembly and storage.

The carriage is factory pre-lubricated and a reservoir supplies long-term guide rail lubrication, for smooth operation. The carriage end-cap seals have also been specially designed to ensure that the lubricant remains within the carriage and that contaminants are excluded from the recirculating ball system.

The rail guides offer very low, or near-zero maintenance, essential for components destined for repetitive processes such as robotic sampling, 3-D printing or critical medical equipment application.

In addition, carriages and rails are interchangeable within the same preload and precision classes due to Ewellix’s 'Zero Rail' design concept, maximising design and assembly flexibility and enabling significant reduction in OEM inventories.

The LLS Series has been sized according to market requirements, with carriage sizes 7, 9 and 12 in standard or extended lengths. Depending on the application, a low friction shield, or a front seal for more demanding environments, are available. Rails are supplied in lengths of up to 1,000 mm as standard and longer lengths are available to order.
