Feature 2: Design that responds to the performance needs of machine tools

The BSM improves load capacity with a unique groove design and double groove structure.

 

Feature 3: Achieves higher rigidity and a more compact nut diameter than our conventional products.

The BSM-B conserves space with a slimmer nut compared to our conventional products. Rigidity was also improved by extending the overall length and increasing the number of loaded circuits.
