Size options of metal-cased HDS seals and all-rubber HS seals All SKF metal-cased HDS seals and all-rubber HS seals are made upon order in any inch or metric size within the ranges listed in tables 19 and 20. Since new sizes are manufactured without additional tooling, they can be supplied without extended lead times. The product tables starting on page 216 and 302, respectively, list a selection of sizes. For any size that is not listed in the product tables, contact your SKF distributor or SKF sales representative. 2 Table 20 Standard size options of HS seals Shaft diameter 1) Bore diameter 2) Bore depth 3) Difference between bore and shaft diameter from to from to from to from to mm/in. mm/in. mm/in. mm/in. 165,10 4 572,00 190,50 4 597,40 12,70 25,40 6.500 180.000 7.500 181.000 0.500 1.000 165,10 4 572,00 195,10 4 602,00 12,70 19,99 30,00 50,80 6.500 180.000 7.681 181.181 0.500 0.787 1.181 2.000 330,20 4 572,00 368,30 4 610,10 16,51 25,40 38,10 63,50 13.000 180.000 14.500 181.500 0.650 1.000 1.500 2.500 1) Tolerance h11 2) Tolerance H8 3) Tolerance ±0,13 mm (0.005 in.)
