In harsh operating conditions or during reversing operation, the keyway width tolerance P9 must be preferred. The shaft keyway width has to be specified with the tolerance N9. With two parallel keyways, the keyway width tolerance JS9 should be specified in order to simplify the assembly. -26 -74 260 290 63 32 20 12.4 +0.3 +37 -32 290 330 70 36 22 14.4 +0.3 +37 -32 330 380 80 40 25 15.4 +0.3 +37 -32 above up to keyway depth -31 -88 -31 -88 95 110 28 16 10 6.4 +0.2 +26 -22 110 130 32 18 11 7.4 +0.2 +31 -26 height depth depth shaft & hub keyway width B -31 -88 Diameter Keyway width Parallel key Shaft keyway Hub keyway Deviation for Deviation table for D D B H T1 T2 JS9 P9 150 170 40 22 13 9.4 +0.3 +31 -26 170 200 45 25 15 10.4 +0.3 +31 -26 130 150 36 20 12 8.4 +0.3 +31 -26 -31 -88 200 230 50 28 17 11.4 +0.3 +31 -26 230 260 56 32 20 12.4 +0.3 +37 -32 -37 -106 mm mm mm mm mm mm mm μm μm -31 -88 -37 -106 -37 -106 -37 -106 380 440 90 45 28 17.4 +0.3 +43.5 -37 -43.5 -124 440 500 100 50 31 19.4 +0.3 +43.5 -37 -43.5 -124 14 #DriveLineHarmony Fitting Recommendations Mechanical Power Transmission Couplings
