High-Speed Ball Screw for Machine Tools BSM
With high-speed performance that exceeds prior full ball standards, the BSM achieves even higher load capacity.
Feature 1: High-speed performance
DN value greatly improved from 130,000 in conventional products to 170,000 with a newly developed circulation structure. Utilizes a large lead to meet high-speed performance demands. For example, the maximum feed speed of the BSM4030-6 is 121 m/min.

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.
