INTORQ I Clutch-brake combinations I en 5/2007Clutch-brake combinationsShaft loadsThe radial forces specified in the table relate to the centre ofthe shaft ends. F rmax is the maximum permissible radialforce in relation to the shaft strength.Force F rated underlies a bearing service life ofL h = 10,000 hours at n = 1500 rpm.These values can be converted to other service lives andspeeds with the aid of the diagram. However, you shouldensure that force Frmax is not exceeded. If additional axialforces are present, please inform us of them so that we canperform a recalculation.INTORQ 14.800 INTORQ 14.810F r max.F r max.F r max.Size Force ForceF rmax [N]F rated [N]06 600 32508 900 42510 1300 59012 1900 87016 2300 1350Correction factor3.02.52.01.51.0F= F rated · k F rmax0.5500 1000 1500 2000 2500 3000Speed n [rpm]L h =2000L h =5000L h =10,000L h =20,000F Permissible radial force in NF rmax Max. permissible radial force in N,in relation to shaft strengthF rated Permissible radial force in N for L h = 10,000 hand n = 1500 rpmk Correction factor from diagramExample:Size 08Speed n = 500 rpmService life L h = 5000 hoursF = 425 · 1.8 = 765 N < F rmax = 900 N17
