High reliability under harsh moment loads! Significantly reduce maintenance costs.
Under usage conditions where moment loads are applied, such as vertical use with cantilever support, several times to over a dozen times the load acts on the linear bearings, which can lead to early failure. To address this issue, the 'U Ultra Series' has been developed through years of research. It is compatible with almost all of our linear bearing series, and since the outer dimensions remain unchanged, it allows for an ultra-long lifespan that is 18.5 times longer than conventional products, leveraging our accumulated experience and processing technology without the need for design changes. 【Features】 ■ Achieves an ultra-long lifespan 18.5 times longer than conventional products ■ Reliable performance even under harsh usage conditions ■ Compatible with almost all of our linear bearing series ■ No design changes required as outer dimensions remain the same *For more details, please refer to the PDF document or feel free to contact us.
