SKF LLT profile rail guides from SKF Motion Technologies, Inc. have been uniquely designed to deliver smooth running performance, high precision and accuracy, and long service life with minimal maintenance for a wide range of linear guiding applications.
LLT guides have the ball circuits placed in an X-arrangement, which optimizes load sharing in all four main load directions and accommodates moment loads, while maintaining self-aligning capability. The arrangement further compensates for mounting deviations, even under preload, contributing to smooth running performance under a variety of operating conditions.
Guides are available in sizes 15 to 45 with rail lengths up to 4000 mm in a single piece and longer lengths available as attached rails. LLT guides are available with a variety of preload and precision classes, mounting configurations, and accessories. They can resist temperatures up to 100º C and achieve speeds up to 5 m/s. The use of eight carriage types with a single rail profile to meet most industry-standard dimensions greatly increases flexibility.
LLT guides are supplied ready-to-mount and are factory pre-lubricated. Carriages are equipped with end seals, side seals, and inner seals, as well as an internal lubrication reservoir for extended maintenance intervals. Many components are already in stock for immediate shipment, and guides can be cut to length within days for up to 10 systems.
