Bearings for high speed operations· By reducing the diameter of a ball to 75 % a real case the mass will be reduced to 42 % Example Bearing 7014 CD having a ball diameter of 12 7 mm is running at 15 000 r/min The centrifugal load from each ball is then 174 N If the ball diameter is reduced to 7 938 mm % the centrifugal load from each ball is 79 N a reduction to 45 %
Ball screw preload What you need to know· Another effect of ball screw preload is that it induces an internal load on the ball nut which needs to be considered during sizing to ensure the motor can produce sufficient torque for the application Preload is specified as a percentage of the ball nut s dynamic load capacity so in order to determine the internal load due to preload the preload amount for 2 percent or for 7
