Characteristics of oil-free nuts for 30-degree trapezoidal screws

An oil-free nut has the same effect as a nut that is lubricated every 45 hours, as shown in the wear test results shown on the right.

After applying initial running-in grease, it can continue to operate without lubrication.

Especially when used at low speed, it can achieve better performance.
