Precision Roller Chain, Elements and Connecting Backlinks
The precision steel roller chain is a highly efficient and versatile means of transmitting mechanical power, which, during the discipline of industrial applications, has pretty much entirely superseded all other sorts of chain previously applied.
Outer Website link – Press Fit (BS/DIN) Riveting Pin Link – Press Match (ANSI)
For use with all sizes and varieties of chain wherever optimum safety is preferred. The link is provided with bearing pins riveted into 1 outer plate. The other outer plate is an interference fit within the bearing pins, the ends of which should be riveted over just after the plate is fitted. Press match connecting links need to only be applied once; new backlinks must be applied to exchange dismantled hyperlinks. (See ‘Riveting Chain Endless’ for full instructions).
Connecting Website link – Slip Fit (BS/DIN/ANSI)
A connecting link provided with two connecting pins riveted into the outer plate. The outer plate can be a clearance match about the connecting pins and it is secured in place by a split pin through the projecting finish of every connecting pin.
Connecting Website link – Slip Fit (BS/DIN/ANSI)
Made use of on brief pitch chains only. Provided with two connecting pins riveted into the outer plate, the clearance match connecting plate remaining secured by way of a spring clip, No. 27, which snaps in to the grooves within the pins.
