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 (0.02 for 2 percent, or 0.07 for 7

Tips for Selecting a Lubricant for Ball Screws

Ball nut operating temperature should be approximately 20°C, but this is seldom the case in real operation. Usually, a ball nut stabilizes a few degrees above screw shaft operating temperature. If you can’t measure nut temperature, assume it to be 30°C for your initial selection of oil viscosity. Required oil flow rate is a function of:

FAR Driven Nut Bosch Rexroth USA

In a traditional ball screw assembly, where the screw rotates, the speed is limited due to a whipping action of the screw. With the FAR, the screw remains stationary and the nut is rotated to achieve linear motion. This not only permits greater speeds, but also greater strokes. Rexroth's FAR nut is a great fit if your application requires high speeds and precision and also has the following

Ball Screws ABSSAC

The nut in any ball screw application is essentially a device that constrains relative motion to a desired motion, and does so with minimal friction between the moving parts. Therefore the match between the screw thread and the nut thread is critical and ABSSAC only supplies ballscrew and nut threads that are matched to give optimum performance. ABSSAC have standard nut designs to suit most

Thomson® Ball Screws High Load Ball Screws

The interface between the ball screw and the nut is made by balls which roll in matching ball forms. With rolling elements, the ballscrew drive has a very low friction coefficient and is typically up to 98%. The forces transmitted are distributed over a large number of
