Ball-screw spindles and nuts
Ball-screw spindles are right-hand threaded spindles featuring a ball connection between nut and spindle. Thus, rolling friction is provided in contrast to the sliding friction of the trapezoidal thread spindles. This offers a variety of advantages: Efficiency of more than 90 % (trapezoidal-thread spindles only 20–40 %) Minimum of wear, therefore long life Starting torque only 1/3 of conventional threaded spindles (no stick-slip, but also no self-locking capacity). Longitudianl motion convertible into rotary motion. Minimal lubrication – similar to ball bearings. Atlanta ball-screw spindles are very favourably priced and yet suffciently accurate to justify their employment in many types of application. The hardened thread profle is a rolled pointed-cone profle. The balls mesh under load at approx. 45°. We are glad to rework the tips of our standard ex-stock spindles on request. Spindles and nuts are always supplied separately (spindle and nut detached). A sleeve provided in the bore of the nut prevents the balls from getting lost and serves as mounting aid at the same time. Lubrication is effected directly into the nut via a threaded hole. Only in cases where lubrication is not possible in this way, grease or oil can be applied directly onto the spindle. Please note that our standard ball-screw nuts are provided with dirt-repellent wipers on both sides since contamination results in increased wear.
