The startup and growth of SKF depends not only on technical inventions but also on industrial and corporate management strategies and power. Axel Carlander was a co-founder of SKF as a co-owner and member of the board of Gamlestadens Fabriker AB, which corporate policy provided conditions for experimenting with the new bearing models and the startup of SKF, and also he was the first chairman ...
The length of a fully stretched chain is = for the Kuhn segment chain. [5] In the simplest treatment, such a chain follows the random walk model, where each step taken in a random direction is independent of the directions taken in the previous steps, forming a random coil .
An RF chain is a cascade of electronic components and sub-units which may include amplifiers, filters, mixers, attenuators and detectors. [1] It can take many forms, for example, as a wide-band receiver-detector for electronic warfare (EW) applications, as a tunable narrow-band receiver for communications purposes, as a repeater in signal distribution systems, or as an amplifier and up ...
An example of a sintered metal bearing in action can be seen in self-lubricating chains, which require no additional lubrication during operation. Another form is a solid one-piece metal bushing with a figure eight groove channel on the inner diameter that is filled with graphite. A similar bearing replaces the figure eight groove with holes ...

In condensed matter physics, the Kitaev chain is a simplified model for a topological superconductor. It models a one dimensional lattice featuring Majorana bound states . The Kitaev chain have been used as a toy model of semiconductor nanowires for the development of topological quantum computers .
It uses type slugs on a chain and is the first IBM printer to do so. In 1967 the IBM 1403 Model N1 is the first IBM printer to use a train rather than a chain. This change is made because it is not possible to achieve higher speeds using a chain. It is called a train as the print slugs move inside a machined track, resembling rail-road cars. [3]
Bicycle chains Roller chain and sprocket. A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it.Most bicycle chains are made from plain carbon or alloy steel, but some are nickel-plated to prevent rust, or simply for aesthetics.
