Frequently Asked Questions
What ambient conditions are needed for a ball screw?
Most ball screws can be used in ambient temperatures ranging from -4 to +194°F. It is possible to go up to 230°F by altering the material of the liners, which divert the balls from their track.
Are ball screws energy efficient?
Ball screws are energy efficient. Ball screw systems are able to achieve linear motion with average system efficiencies of 90%. This far exceeds linear actuators and screw jacks (generally 40% and 25%, respectively). In addition, ball screws are advantageous in that no energy is required while they are at a standstill, unlike with pneumatic and hydraulic systems, which require continued pressurization.
What is the lifetime of a ball screw?
The lifetime of ball screws varies based on the actual loads, rated loads, any shock loading, and the speed. If a target lifetime is specified, adjustments can be made to the features and sizing of the ball screw in order to achieve it.
What performance is possible with a ball screw?
Dynamic load ratings for industrial ball screws typically range from 1 to 150kN. In practice, however, operating factors will reduce these loads. Speed, load, and duty cycle effect performance and lifetime. Dynamic load ratings are based on 1,000,000 revolutions at that load. Linear speed depends on the rotation speed of the screw and the pitch of the screw (which is generally between 5 to 40mm). Linear speed of 2m/s can be achieved for light loads. Any and all loads should ideally be in-line with the screw, as radial loads are adverse to lifetime.
What is the difference between a ball screw and a lead screw?
The major difference between lead screws and ball screws is the way in which the load is carried. A ball screw uses recirculating ball bearings in order to minimize friction while, at the same time, maximizing efficiency. A lead screw, on the other hand, depends on low coefficients of friction between sliding surfaces rendering them unable to achieve the same level of efficiency as a ball screw. With applications requiring higher precision and performance, ball screws are used. An example of this would be a CNC machining center. Lead screws are most often used in OEM applications such as drilling machines.
