Features
Improves the Quality of Machined Surfaces
We have stabilized drive-induced frictional forces by cracking the code on the contact happening inside the ball screw during operation. This improves the dynamic accuracy of equipment motion and the quality of machined surfaces.
Reduces Energy Consumption
THK's proprietary friction-reducing technology lowers dynamic friction torque by over 50% which decreases the amount of energy consumed while the device is in operation.
Significantly Reduces Heat Generation
THK's proprietary friction-reducing technology minimizes heat generation, limiting the thermal impact on surrounding equipment and improving the operating conditions of the device itself.
Multiple Clearances (Preloads) Available to Suit Your Application
We offer multiple negative clearance (preload) options so you can select the one that suits your application and rigidity requirements.
- Note: We can also provide special clearances other than G0 and GM. Contact THK for details.
Load Capacity Equal to Existing Products
This model has the same mounting dimensions and load-bearing capabilities (basic load rating and axial rigidity) as earlier products. The external dimensions conform to ISO 3408-2: 2021 (JIS B 1192-2: 2025) Series 3.
