DN value 170,000 High-speed ball screw for machine tools 'BSM': THK

DN value 170,000 High-speed ball screw for machine tools 'BSM': THK

The new ball circulation system achieves a maximum high-speed performance with a DN value of 170,000 and a full ball type, while also realizing a higher load capacity.

- High-speed performance The newly developed circulation structure significantly improves the DN value. A large lead is adopted to meet the demands for high-speed performance. - Design that meets the performance requirements of machine tools Groove design that achieves increased load capacity. BSM realizes improved load capacity through its unique groove design and two-row groove structure. - Compact and high rigidity Compared to conventional products, the nut outer diameter is compact while achieving high rigidity. BSM-B contributes to space-saving design by slimming down the nut outer diameter compared to our conventional products.

Compact Precision Ball Screw with Ball Retainer 'SDA-V': THK

Compact Precision Ball Screw with Ball Retainer 'SDA-V': THK

This is a compact precision ball screw with a ball retainer from THK that adopts a tangent direction scoop. It enables high-speed and compact equipment.

A new technology has been adopted that realizes an ideal ball circulation structure in the ball screw nut, enabling smoother rotational motion. The use of a ball retainer has achieved a maximum rotational speed of 5,000 min-1 (DN value: 160,000 MAX). The outer diameter ratio of the nut has been reduced by up to 30%. The dimensions of the nut comply with DIN standards [DIN69051-5]. *As of September 2021, the lineup of SDAN-V shapes has been expanded.

THK Precision Ball Screw

THK Precision Ball Screw

This is a ball screw that uses a screw shaft and ball screw nut that have been processed with high precision!

THK precision ball screws are standardized in a wide variety of types, allowing for the selection of the optimal product according to the application, with high-precision grinding processing performed on the screw shaft and ball screw nut. The nut and screw shaft of the ball screw can convert rotational motion into linear motion or linear motion into rotational motion through rolling motion via balls. The balls can perform infinite motion by being returned from the end face of the ball screw nut to the circulation components.

THK rolled ball screw

THK rolled ball screw

This is a ball screw that uses a screw shaft formed by high-precision rolling processing!

The rolled ball screw is a transportation ball screw that undergoes high-precision rolling processing and hardening, followed by a special grinding finish on the screw shaft. By combining it with a precisely machined ball screw nut, the axial clearance is minimized. As a result, it offers excellent reproducibility and smooth operation. For more details, please contact us.
