A wood producer in the UK manufactures wooden beams for the construction industry, mainly housings. The walking beam moves the beams along a parallel track. It uses 20 mm linear guides in a back and forward motion - with rapid changes in direction. The far eastern linear guides were not capable of withstanding the forces caused by the direction changes, and fail about every 2 weeks in one of the many machines. NSK investigated the failures and recommended NSK linear guides with K1 seals. Since fitting, the NSK Linear solution has been running for over 6 months without a single failure, saving downtime, fitting time, and associated frequent purchasing costs.
