Ball Screw Or Lead Screw

Choosing between a lead screw and a ball screw is relative and will likely depend on the application. Often the decision must be made as to whether a lead screw assembly or a ball screw assembly will work best in the application. The ball screw drive is an assembly that converts rotary motion to linear motion or vice versa.

The screw and nut on a ball screw have matching helical grooves that allow ball bearings to re circulate in those races and are typically semi circular in shape to accept.

Ball screw or lead screw. Ball screws may also reduce or eliminate backlash common in lead screw and nut combinations. Lead screws vs ball screws when determining which types of screws is best for a movement centric application an engineer has several options. They feature a number of variables including type of nut screw diameter screw pitch material etc. Ball screws and nuts internal ball bearings provide smooth low friction travel in applications that require high speeds accurate positioning and repeatable movement.

This is an important specification not only for linear travel and speed but also because a ball screw s lead determines how many balls are in the load zone in contact with the screw shaft and ball nut and therefore has a direct impact on load capacity. It consists of a ball screw and a ball nut packaged as an assembly with recirculating ball bearings. Offered in diameters from 16m to 63mm. Feature 25µm 300mm lead accuracy ball screws with precision ground preloaded ball nuts that are an economical high performance alternative to ground thread ball screw assemblies.

They convert input torque from rotary motors into linear motion. For example on a vertical application it may be more beneficial to use a lead screw than a ball screw as the lead screw cannot back drive itself. A set of ball bearings reduces friction and secures the end of a ball or lead screw. The basic difference between lead screws vs ball screws is that a ball screw uses ball bearings to eliminate the friction between the nut and screw and lead screws do not.

25µm 300mm lead accuracy ball screws with high efficiency and long life. This is particularly desirable in applications where the load on the screw varies quickly such as machining tools. Lead screws and ball screws lie at the heart of screw driven stages and actuators. The balls may be preloaded so that there is no wiggle between the ball screw and ball nut.
