Ball screws feature high speed, high load capacity for machine tool applications

Featuring high-speed performance and load capacities that exceed existing full ball standards, THK’s new Type BSM ball screw is ideal for use in machine tools. The Type BSM uses a newly developed circulation structure and a large lead to meet high-speed performance demands. The DN value is 170,000, contrasted with 130,000 in conventional products. The unique groove design and double groove structure of the Type BSM improve load capacity, and meet the requirements of machine tool applications.

The Slim Nut Type BSM-B conserves space with a nut diameter up to 14% more compact than THK conventional ball screws. An extended overall length and increased number of loaded circuits ensures optimum rigidity. The Type BSM is available with screw shaft outer diameters ranging from 36 to 63 mm with maximum speeds of 5,000 rpm.

THK manufactures the widest range of linear motion products, including LM guides, ball screws, mechanical actuators and ball splines and more. All THK products have been designed and manufactured to meet the strictest requirements. THK’s experienced Global Engineering Team can provide customized linear motion solutions from their standard linear motion products as well as from mechatronics products for the most demanding applications.
