Basic design

SKF supplies metric adapter sleeves with a metric or an inch bore and inch adapter sleeves. The sleeves are slit and supplied complete with a lock nut and locking device. Smaller sizes use a nut and a lock washer (fig. 1). Larger sizes use a nut and a locking clip (fig. 2) or locking plate (fig. 3).
Metric sleeves with a bore diameter ≤ 180 mm (size ≤ 40) are phosphated. Larger metric sleeves and all inch sleeves are coated with a solventless rust inhibitor.
Adapter sleeves listed here constitute the basic SKF assortment and are only part of the total assortment. For larger sizes (bore diameter ≥ 1 060 mm) and variants not listed in the product tables, contact SKF.
