A new video by igus explains what limits the length of its drylin linear module's leadscrew. Designed for axial movement, the leadscrew should have a clearance between it and the nut - this ensures reliability and quiet operation. When the clearance between the nut and leadscrew increases, the leadscrew 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 igus' catalogue users will find details on the maximum stroke length for different size leadscrews. Specialised options are available to fit the customer's needs, should they exceed the standard maximum length.
