This design enables various mounting methods other than conventional pillow blocks and press fit ball bushings. They feature a compact design with excellent rigidity and high accuracy. Standard and anti-corrosion options are available. Metallic retainers (for use in harsh environments), and low cost resin retainers are also available. These bushings are fully compatible with a variety of shaft types. The raceway surface is precision ground providing low friction when compared to other linear motion mechanisms.
