SKF SNW 28X5 Bearing Adapter Sleeve

SKF SNW 28X5 Bearing Adapter Sleeve is a steel, tapered adapter sleeve with a 5.000 in bore designed to locate a tapered‑bore bearing on a shaft and secure it with a locknut and washer. Part of SKF’s SNW series, this SNW 28×5 configuration has a total length of 3.98 in (101.12 mm). The sleeve slides onto the shaft and, used with the locknut and lock washer, provides the mounting interface between bearing and shaft and enables axial preload to prevent loosening in operation. Some distributor listings show SNW 28X5 shipping with a nut and washer. Typical applications include industrial equipment where bearings with tapered bores are mounted on a shaft—in pillow block housings or similar units that accept SNW adapters—such as conveyors, pumps, motors, and gearboxes. The SNW series is designed for installation with standard locknuts and washers to secure the bearing after set preload.
