dryspin pre-loaded PreLoad lead screw nut made of iglidur J | Thread: DST thread | RH

What is axial clearance and how can it be prevented?
Axial clearance describes the lost motion, the "dead travel", on the lead screw as a result of the gap between the lead screw and the lead screw nut. The term clearance is also often associated with this, but the correct technical term is axial clearance. 

Pre-load (PL) lead screw nut
The PL lead screw nut is impressive due to its minimal axial clearance and highest positioning accuracy. It is the cost-effective alternative to the zero-backlash lead screw nut and is ideal for small pitches. It is based on the proven pre-load principle from our SHT-PL linear axes. Typical application areas are e.g. 3D printers, the medical sector for e.g. pipetting or adjustments with a high required positioning accuracy.

► For thread diameters from 6.35 to 10mm
► For pitches from 1mm to 12mm (DS10x12)
► Thread direction: right-hand thread and left-hand thread possible
► Material: iglidur® J 

Important note:
For applications with high loads, high temperatures or in extremely dirty environments, a standard lead screw nut is generally used. The reason for this is that the effect of all three principles is cancelled out by excessive load. For this reason, the maximum static axial loads are specified separately for each lead screw nut variant.
