Shell Type Needle Roller Bearings

Shell type needle roller bearings use a thin, formed steel shell as the outer race. This shell presses directly into a machined housing bore, eliminating a separate outer ring and shrinking the radial envelope versus a machined ring bearing. One common construction, the drawn cup, forms this shell by drawing steel into a cup shape rather than machining it. These bearings span both metric and inch dimensions, in caged and full-complement roller designs, with open-end and closed-end variants for through-shaft and blind-bore mounting.

• Metric and inch coverage. Shell bearings are available in both metric and inch dimensions for either housing standard.
• Caged or full-complement rollers. The lineup includes caged designs, which support smooth high-speed rotation, and full-complement designs, which pack in more rollers for higher load density.
• Open or closed end. Open-end shells pass a through-shaft, while closed-end shells seal a blind bore without an extra plug.
• Wide size range. A broad span of bore and outer-diameter sizes supports everything from small components to mid-size machinery.
