Temperature lead screw nuts

Zoe Moser | 23. April 2021

Lead screw drives are used in many machines in a wide variety of industries. Thus, the demands placed on a lead screw drive also differ: from high and low loads to high and low speeds to large temperature spans or even permanent temperatures around 200°C. Of course, the screw drives used should also perform flawlessly here.

In general, efficiency indicates how high the effectiveness of a device is when conversion losses are taken into account. The efficiency describes the relation between the delivered power (effective output) and the supplied power or loss and expenditure. In the calculation, the efficiency is abbreviated with a small eta (η). The result of the efficiency depends on what is considered a benefit or loss and what is considered an expenditure.


Thread size 10×3

The thread is a profiled indentation that runs along a helical line wound around a cylinder. The type of lead screw is defined by the profile shape, the pitch, the number of threads and the direction of rotation. You will find more terms related to lead screws in another blog post. Basically, lead screw drives are machine elements that convert rotary movement into linear motion. In this blog post we look at one of the common thread sizes: the 10×3 thread size.


Lubricating polymer lead screws

It is no secret that igus® is an advocate of non-lubrication of bearings. Simply put, lubrication is not required for igus® products. But that doesn’t stop customers from asking the recurring question: “Can I use WD-40 or another lubricant to grease my bearing?”


Lead screw support
