SELECTING A CHAIN TENSIONER<br />
Even though our extensive standard range covers most applications, for best<br />
results a number of factors should be taken into account prior to selecting a<br />
particular chain tensioner.<br />
That is why we offer our clients a free-of-charge advisory service. Our Service<br />
Department will be pleased to contact you on request, answer your queries and, if<br />
required, prepare drawings of the best solution for your problem.<br />
The following points need to be clarified in order to suggest a suitable<br />
installation method:<br />
• chain sprocket configuration;<br />
distance between conveyor centres (please provide a sketch)<br />
• chain type<br />
• overall length of chain<br />
• single direction of travel or reversible drive?<br />
• chain speed (we can make appropriate recommendations if it exceeds 1m/s)<br />
• is the chain lubricated or dry running?<br />
• continuous or intermittent operation?<br />
• do you expect dirt to accumulate on the chain (scales, wood chips, bore chips)<br />
which might accelerate wear on plastics?<br />
• is the tensioner subject to temperatures above 60°C?<br />
• chemical influences<br />
