This extra wide design has a greater load capacity than the standard SWF & SWK types and enable 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 available. Metallic retainers ( for use in harsh environments and low acoustic), and low cost resin retainers 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.
