With eLINE ball screws it is now very easy to realize many different transport applications with standard products where customized solutions were often required up to now. eLINE ball screws are available ex stock, preassembled with nuts in screw-in or flange versions.
Unilateral screw end machining for the fixed bearing permits easy combination with LGL bearing units, complete with matching slotted nuts. Special attention was paid to the load capacity of the bearings. For small screw diameters the bearing journal diameter was enlarged by friction welding, thus increasing the load capacity of the end bearing arrangement.
Less stringent tolerances enable very economical solutions. For example, the mounted nut is always with clearance.
Seals are integrated as standard.

The LPR Series is a rolled ballscrew offering a lower cost than ground ballscrews. Return tube or end cap recirculation systems are available and square nut designs are offered for ease of installation on these ball screws. Shafts are available in standard, off-the-shelf lengths or can be cut to length.
The HTF-SRC series ballscrew evolved from the best-selling HTF series ballscrew designed for heavy load applications such as injection molding machines and other factory automation applications within the machine tool industry. They feature high speed and low noise. This ball screw series works effectively with heavy load driving machines that require high speed and high acceleration.
NSK's HMC series ball screw is specially designed to provide the high performance and speed required for machine tool applications. This ballscrew offers high speed linear motion, low vibration and noise, high rigidity, high load capacity, and compact nut design.

0.5mm Lead Ball Screw Series
The 0.5-mm lead ball screw series leads the way in the miniaturization of precision positioning devices.
A series of 0.5-mm lead ball screws has been created to meet requirements for small-sized and fine-feed ball screws necessary for reduced-size precision positioning devices.
This allows further size reductions in machinery and control units.
