Airtac LSH Linear Guide Rail LSH25BK-F2L-P-B-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25BK-F2L-P-B-M6 is a standard-type profile linear guide on a 23 mm wide rail. Four rows of balls contact X-shaped raceways at a 45° angle, so the guide carries load equally in all four directions and absorbs small mounting errors inside the carriage instead of binding.
