Designed for axial movement, the lead screw should have a clearance between it and the nut; this ensures reliability and quiet operation. When the clearance between the nut and lead screw increases, the lead screw begins to sag. This has negative effects on the operation as it causes increased friction, creating excess noise and wear, leading to premature failure.
In the Drive Technology section of the igus catalogue, users will find details on the maximum stroke length for different size lead screws. Specialised options are available to fit the customer's needs, should they exceed the standard maximum length.
