LINEAR MOTION
PRODUCTS TRANSPORTATION BALL SCREWS
Transportation ball screws provide a cost-effective alternative to precision ground ball screws. The manufacturing process is ideal for applications that do not require the finite precision of a ground ball screw, but must still reliably transmit linear loads and provide high speed yet accurate positioning. For such applications, NSK’s transportation ball screws – the PR/LPR and BS Interchangeable series – are in high demand.
These are suitable for woodworking, sheet metalworking, packaging
operations, pick and place systems, automated transfer units, etc. Both deliver fast cycle times thanks to a permissible rotational speed of 160,000 dn (up to 5000 rpm), with high precision. The PR/LPR and BS Interchangeable ball screws also include NSK’s end
deflector recirculation system, which helps to facilitate the aforementioned high speed. The end deflector, with its optimised (smooth) ball recirculation design, also reduces noise emissions. NSK’s optional K1 lubrication unit, meanwhile, applies grease throughout a machine’s life. NSK’s LPR/PR series of zero backlash transportation ball screws are
preloaded and pre-assembled, and are available in lengths up to 4m. The main characteristic of NSK’s BS Interchangeable transportation ball
screw series is the separately available shaft and nut, which are universally exchangeable for easy installation. This free interchange of nut and shaft also means that the machine builder or an authorised NSK dealer can cut the ball screw to length as necessary.
