Ideal for single-direction motion applications, these standard linear bushings are available in wide variety of shaft shapes and materials — chrome or stainless steel with either a steel or resin retainer. These bearings contain internal seals (UU), and the slide block housings are available in several styles.

The SW series is available in standard, adjustable, or open style; open style incorporates bottom plates and mounting screws to ensure bushings remain in the proper position.

Available Dimensions:

Shaft Diameter (dr): 0.25 in. to 4 in.

Outer Diameter (D): 0.5 in. to 6 in.

Length (L): 0.75 in. to 8 in.

Distance Between Retaining Rings (B): 0.511 in. to 6.258 in.

Retaining Ring Width (W): 0.039 in. to 0.1389 in.

Retaining Ring Diameter (D1): 0.4687 in. to 5.745 in.

Dynamic Load (C): 206 to 14,100 CN

Static Load (Co): 265 to 34,800 CoN

Configuration: Open, standard, and adjustable types are available.

Seal Type: Seals on both ends are available, as well as no seals.
