Radial shaft seals Designation system Metric radial shaft seals Designations of all SKF metric radial shaft seals specify shaft diameter, housing bore diameter and nominal seal width (bore depth for HSF and HS seals) in millimetres, followed by design and the code of the sealing lip material († table 12). Inch-size radial shaft seals Inch-size SKF radial shaft seals are identified by their stock number that consists of four to seven digits. The stock number provides an indication of seal size. Assortment and availability The SKF assortment of radial shaft seals comprises some 200 designs and executions for applications within basically all industries. The radial shaft seals described in this publication belong to the standard range and most of them are available in both metric and inch sizes. New seal designs and sizes are continually added. For additional information, contact SKF. Four-figure numbers are used for radial shaft seals for shaft diameters: d 1 ≤ 1 in., e.g. 3680 d 1 = 0.375 in. Five-figure numbers are used for radial shaft seals for shaft diameters: d 1 ≤ 10 in., e.g. 41287 d 1 = 4.125 in. 97545 d 1 = 9.750 in. Six- and seven-figure numbers are used for radial shaft seals for shaft diameters: d 1 ≥ 10 in., e.g. 120061 d 1 = 12 in. 1375242 d 1 = 13.75 in. 88
