ISO-Compliant Dimensions Super-Low Waving Model SPH

By adopting eight rows of raceways and small-diameter balls, the number of load-bearing balls within the LM block has been increased. This in turn enables the highest level of waving performance among THK LM Guide products, with super-low waving on a nanometer-level scale.
