The holding (braking) force for dry running or mineraloil wetted shafts is not less than 2 x M, but will not exceed 3,5 x M. 2 Minimum operating pressure is 40 bar. In case a spring base is installed, for releasing without lifting the required pressure is 60 bar, conf. „Technical Information TI-A10“. Admissible working pressure is 250 bar. 3 As supplied port LL is plugged by a plug screw. It may be used alternatively to port L and is usefull for air-bleeding. It is generally recommended to install the Auto-Bleeder as descibed in the „Technical Information TI-Z10“ at port LL (or L respectively). 4 Hydraulic operating volume. 5 Proximity switch holders are provided for standard proximity switches M12x1 shielded and with a nominal switching distance of 2 mm. 6 Port T is used for pressure compensation (breathing). It is plugged with an air filter element. If, however, moisture or aggressive media are present, a hose instead of the filter must be installed to connect the device with a clean atmosphere (e.g. hydraulic tank). 1 4 Type Ident.-No. d M D D1 H Y Z X L1 G1 T1 L2 G2 T2 V AG HL H1 H2 Weight mm kN mm mm mm mm mm mm mm mm mm mm cm3 mm mm mm mm kg KR 25 KR 025 10 25 10 71 81 152 5 40 3 56 M6 15 64 M5 12 3 G1/4 48 84 130 4 KR 28 SK 028 007 28 15 82 92 169 5 45 3 65 M8 15 73 M5 12 4 G1/4 50 88 145 6 KR 32 SK 032 022 32 21 87 98 189 6 50 3 70 M8 15 78 M5 12 5 G1/4 50 88 165 7 KR 36 SK 036 023 36 33 106 123 211 8 52 3 80 M8 25 56 M6 12 5 G1/4 62 141 186 13 KR 40 KR 040 10 40 33 106 123 211 8 52 3 80 M8 20 56 M6 12 5 G1/4 62 141 186 13 KR 45 SK 045 058 45 40 120 138,8 230 8 60 3 100 M10 25 - - - 9 G1/4 64 114 204 18 KR 50 SK 050 061 50 52 125 142 264 8 65 3 110 M10 25 - - - 10 G1/4 64 119 235 24 KR 56 KR 056 10 56 67 140 156 262 8 70 3 115 M10 25 75 M6 12 11 G1/4 72 187 235 24 KR 63 SK 063 014 63 100 160 177 285 10 80 5 140 M10 25 85 M6 13 12 G1/4 66 251 125 38 KR 70 KR 070 10 70 107 172 188 302 10 90 3 140 M10 25 100 M8 16 15 G1/4 73 129, 270 45 KR 80 KR 080 10 80 133 194 211,8 322 10 100 3 160 M10 25 110 M8 16 16 G1/4 72 128 290 62 4 x G2 = ød f 7 / h 6 øD øZe 8 G1 T1 X - 0 , 2 T 2 Y - 0 , 2 H1 H2 H 3 x 2 0 ° ø L 2 L 1 AG AG øD1- 0 , 2 - 0 , 4 6 x 6 0 ° HL Port: release pressure see 2 Alternativ port: release pressure see 3 Port: pressure compensation see 6 Proximity switch port:1 Signal „Load secured“ see 5 Proximity switch port:2 Signal „unclamped“ see 5 L T 1 2 LL Due to tolerances the ports 1 and 2 may be misaligned up to +/-4° relative to port L.
