profiled rail linear guide / high-performance

The SKF profile rail guide LLT consists of a profile rail (fig. 1) with precision-ground raceways and a carriage (fig. 2) containing four rows of balls in an X-arrangement. The square configuration of the raceways results in a guiding system (fig. 3) that provides an equal load carrying capacity in all four main load directions (fig. 4). That offers greater design flexibility since all mounting positions are achievable. Moreover, deviations in parallelism and height, which usually occur in multi-axis systems, can be tolerated for more efficiently, resulting in reliable and smooth operation under a variety of operating conditions.

The SKF profile rail guide LLT provides the customer with the following features and benefits:
Improved running performance
High repeatability and smooth running performance
Modular concept for customized solutions
Stiffness, strength and accuracy for improved production processes
