Easy & Ready-To-Go
If you need ball screw support, we got them! Manufactured from our good friends at Nachi.
These Nachi ball screw supports are prefilled with high performance grease and the seal is integrated into the bearing, making them pretty much maintenance-free. Available with contact or non-contact seals.
The Nachi ball screw support bearings are great for high precision and high-speed processing machines. Installation is easy because preload is already adjusted.
Common Machine Applications
Primarily these ball screw supports are used in high-precision and high-speed machine tools, as well as precision measuring instruments or feed actuators.
Design Benefits of the Ball Screw Support Bearings
- Energy Saving: The ball screw support bearings have a low rotating torque which saves energy.
- Minimal Noise: The ball screw support bearings have a polyamide retainer combined with high performance grease, keeping operational noise low.
- Maintenance-Free: Lifetime seal locks in the high-performance grease and locks out contaminants.
- Easy-to-install: Preadjusted preload makes these bearing supports easy to install.
