Precision Ball Screw with Finished Shaft Ends Model SDA-VZ Lineup Expanded by 79 Types with Addition of ⌀15 and ⌀20 Screw Shaft Diameters

THK CO., LTD. (Location: Minato, Tokyo; President: Takashi Teramachi; hereinafter referred to as “THK”) has expanded its lineup of the Precision Ball Screw with Finished Shaft Ends Model SDA-VZ.

Precision Ball Screw with Finished Shaft Ends Model SDA-VZ is a precision ball screw with a screw shaft that has its end shape standardized to fit the corresponding support unit. The pre-machined shaft ends allow it to be shipped quickly, and it contributes to both higher machine performance and a smaller machine footprint thanks to its high speed and compact structure.

Previously, 151 different types (with screw shaft diameters ranging from ⌀10 to ⌀25) were available. With the 79 that were added (with screw shaft diameters of ⌀15 and ⌀20), the lineup now boasts a total of 230 varieties. The ⌀15 and ⌀20 shafts were originally available only for the compact type, but now standard ISO/DIN-compliant models can also come in these sizes, which will meet even more customers’ needs.

THK will continue to contribute to the performance of a wide range of equipment, from general industrial machinery to precision machinery and high-precision machine tools.

Features

Can be used at high speeds with stable torque

Picking the balls up in the tangential direction enables high-speed rotation at a maximum speed of 5,000 min^-1 (DN value: 100,000) and produces stable torque even when running at high speeds for long periods of time.

Compact shape optimal for space-saving designs

The compact design contributes to decreased equipment size due to a maximum outer diameter size reduction of 30% compared to conventional precision ball screws.
