Product description

Clearance-free and vibration-reducing lead screw nuts

What is axial clearance and how can it be prevented?
Axial clearance can be used to describe the lost motion, the "dead travel", on the lead screw due to the gap between the lead screw and the lead screw nut. The term clearance is also often associated with it, but the correct technical term is however axial clearance. [Link id="268"]

Low clearance:
our LC lead screw nuts are all equipped with two elastomer O-rings. The functional principle is similar to the AB lead screw nut. However, with the help of the LC lead screw nut, a reduction in clearance can be achieved in this case. The O-rings apply a circumferential radial pretension to the thread system, pressing the flanks of the lead screw nut and the threads of the lead screw. This ensures a constant axial and radial pretension of the nut. The high operational smoothness and cost-effective purchase are further advantages of the LC lead screw nut.

► Reduced axial clearance due to circumferential radial pretension
► High operational smoothness due to reduction of possible vibrations
► Cost-effective alternative to zero backlash nut

► In dryspin® high helix and trapezoidal thread up to 14mm thread diameter
► Flange lead screw nut
► Direction of thread: RH
► Material: iglidur® J

What other possibilities does the igus product range offer?
To reduce the unwanted axial clearance, in addition to the correct choice of material, a pretension mechanism has proven to be an effective measure. For our dryspin® high helix threads and trapezoidal threads there are three versions with pretension: Zero-Backlash, Low-Clearance and AB lead screw nut.

^{Important information: for applications with high loads, hot temperatures or in heavily polluted environments, a standard lead screw nut should always be used. The reason for this is that all three principles are cancelled out by too high loads. For this reason, the maximum static axial loads are specified separately for each lead screw nut model.}
