KWVE20-B-S-V1-G2 INA is a high-precision, narrow linear guide carriage for 20 mm rails, designed with a 4-row ball circulation system. Featuring V1 preload and G2 accuracy, it delivers smooth, accurate, and stable motion in demanding industrial environments. Perfect for CNC, robotics, and automated production systems.
The KWVE20-B-S-V1-G2 by INA is a narrow linear guide carriage engineered for applications demanding high precision, rigidity, and compact design. Built for 20 mm linear rails, this model features four rows of recirculating balls in an O-configuration, delivering excellent load capacity and moment resistance in all directions.
Its V1 preload minimizes internal clearance while enhancing stiffness, and the G2 accuracy class ensures precise, low-friction motion - making it ideal for CNC machines, pick-and-place units, industrial robots, and other high-performance automation systems.

1. What is the "V1" preload classification?
The V1 preload class means slight internal preload, improving rigidity and accuracy with minimal increase in friction.
2. What does the "G2" accuracy class provide?
G2 is a high-precision class, suitable for applications that require tight tolerances and smooth, vibration-free motion.
3. Is this carriage compatible with any 20 mm rail?
Yes, it is fully compatible with standard 20 mm linear guide rails in the INA KWVE series.
4. Does this model include end seals or scrapers?
No, this is the open version, which is easier to maintain and suitable for clean environments where contamination is minimal.
5. Where can I purchase this INA carriage?
