For best results shafts with h6 tolerance or 6 254.22 255.22 257.22 259.22 260.22 better, are recommended. Undersized shafts become 6.350 257.24 259.24 260.24 progressively less effective. For similar reasons, flatted shafts with 7 257.25 259.25 260.25 more than 1/4 of their diameter removed are not recommended. 7.938 257.27 259.27 260.27 261.27 8 257.28 259.28 260.28 261.28 9 259.30 260.30 261.30 9.525 259.31 260.31 261.31 262.31 10 259.32 260.32 261.32 262.32 11 260.33 261.33 262.33 12 260.35 261.35 262.35 263.35 12.700 260.36 261.36 262.36 263.36 14 260.38 261.38 262.38 263.38 15 261.40 262.40 263.40 15.875 261.41 262.41 263.41 16 261.42 262.42 263.42 18 261.45 262.45 263.45 19 262.46 263.46 19.050 262.47 263.47 20 262.48 263.48 22 262.49 263.49 22.225 262.50 263.50 24 263.51 25 263.52 25.400 263.53 material brass al. alloy Major diameter D is toleranced 0.013 / 0.050mm Minor diameter B is toleranced +0.03 / 0mm * Short adaptor 254 is used with couplers as indicated in the standard bores tables.
