SWA8UU Pillow Block Linear Motion Bearing 

Key Features

SWA8UU Bearing is a Precision Slide Pillow Block Linear Ball Bushing Unit with Rubber Seals on both sides and a Polyamide Retainer. This SWA8UU is used for high accuracy systems and any application where smooth linear motion is needed. The housing is made from aluminum alloy and uses the SW8UU Linear Ball Bushing as an insert. Our Linear Bearings are Pre-Lubricated with Grease allowing them to be ready to use upon arrival.

Applications / Industries

This SWA8UU Linear Bearing is widely applied to Electronic Equipment, Food Processing Industry, Packaging, Medical Machinery, Printing Industry, Textile Industry, Robotics, Automotives, 3D Printing, and other applications requiring smooth linear motion.

What are Linear Bearings?

Unlike typical bearings that enable circular motion, linear bearings, also known as linear slides, promote movement in a straight line and consist of a movable part and a guide rail. Linear motion is generally accomplished with the use of ball or roller bearings loaded onto a track that supports a surface, which can be moved back and forth, such as a table.

What is the Difference Between Linear Ball Bearings and Linear Ball Bushings?

The main difference between both linear ball bearings and linear ball bushings are the components that put them together and their uses. 

  • Linear Ball Bearings composed of an outer ring, steel balls, and a cage resulting in smooth and precise infinite linear motion. Commonly chosen for smooth linear motion in debris-free environments. When compared with linear sleeve bearings, linear ball bearings create less friction and can be run at higher speeds.
  • Linear Ball Bushings Provide smooth linear motion via ball bearings. Linear bushings consist of an outer cylinder and ball retainer that houses the bushing components. These are commonly used in applications that require smooth, precise motion.
