💡 Why are sealed linear ball bushings used in precision linear motion systems?
Sealed linear bushings are built to keep motion smooth and predictable over long service life.

• Seals help block dust and debris in automated environments

• Multiple ball circuits spread load evenly along the shaft

• Resin retainers reduce noise and keep movement clean

Use this slide unit when you want steady linear travel, low maintenance, and trusted Japanese manufacturing quality.
