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.

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 ball screws proposed by Elitec have various applications or precede the precision, rigidity, the sensitivity and the constancy of positioning. The production schedule includes/understands screws of very high precision has nets rectified as well as a range of screw with rolled nets. The screws are proposed according to DIN standard 69051, or customer plan.

Berg is a pioneer in the development of lead screws. Providing cost effective solutions to linear actuation problems. The close tolerance, free running nuts are ideal for miniature applications requiring rotary to linear or linear to rotary actuation.
For applications requiring precision positioning, Berg manufactures Anti-Backlash Nuts. Consisting of only three components, this device utilizes the constant force of a compression spring to push two nut halves apart. This action eliminates any play (backlash) which exists between the internal thread of the nut and the external screw thread. To ensure accuracy and repeatability, the nut can be fine-tuned by using many available spring constants, to meet any pre-load design requirements.

MRH-BP2 Series
Features
■Manufactured upon order
These are manufactured upon order because the spring on the nut has to be adjusted at the time of shipment(they cannot be removed).
■Backlash free design
Backlash free construction made possible with double nuts and a spring in between.(Patent pending)
■Custom order
Can be manufactured to order in quantities of one of more.
■Water resistant and corrosion resistant
The shaft is manufactured from SUS304,which gives excellent corrosion resistance and enables use underwater of in humid locations.
■Wide range of lead pitches
Different lead pitches can be selected for each screw shaft outer diameter.
■Lubrication-free
MRH incorporates a lubricating agent so it can be used without oiling.
Also,a polyamide type resin with good sliding properties is employed in the standard MRH nut material.
■Smooth transmission
Uses the same gothic arc grooves as ball screws,ensuring smooth transmission.
