What is the PLB v2?
The PLB v2 has been designed to address the issues associated with the self-loosening of a bolted
joint. By design, the PLB v2 consists of a dual-thread screw shaft and two nuts of different thread
pitches. The first, or big lead nut on the shaft, is a multiplies-thread nut. The outer or secondary nut on
the shaft is a single-thread nut.
As for double nuts assembly, vibration initiates loosening with the inner nut. With PLB v2, the inner
nut’s advance is blocked by the slower-moving outer nut.
The mechanical lock is the secret to the PLB v2 Antiloosening design. No other fastener system in the world can make this offer. Most other anti-loosening kits use “friction” for their anti-loosening function
despite its uncertainty. However, PLB v2 has a reliable solution.

Equipment Manufacturers) require these tests? What are these tests and how do the two methods differ? Perhaps this article will add a little clarity to the subject and give you a better understanding of what they are, what they do and why we use them

A technology that is quickly expanding in many fields thanks to competitive features such as optimization of time and production costs and significantly higher product quality, is the rolling process. And this is also true thanks to the technical innovations proposed by ORT ITALIA, an Italian company leading in the rolling process field. ORT ITALIA has its main strength in its research and development department
