Profile Rail Guides with X-arrangement

The newly launched profile rail guide series LLT  from SKF features four rows of balls in an X-arrangement. This design provides an equal load carrying capacity in all four main load directions and therefore greater design flexibility since all mounting positions are possible. Moreover, deviations in parallelism and height, which usually occur in multi-axis systems, can be compensated for more efficiently, resulting in reliable and smooth operations under a variety of operating conditions.
