Even though our extensive standard range covers most applications, for best results a number of factors should be taken into account prior to selecting a particular chain tensioner.

That is why we offer our clients a free-of-charge advisory service. Our service department will be pleased to contact you on request, answer your queries and, if required, prepare drawings of the best solution for your problem.

The following points need to be clarified in order to suggest a suitable installation method:

•      Chain sprocket configuration; distance between conveyor centres (please provide a sketch)
•     Chain type
  
•     Overall length of chain
  
•     Single direction of travel or reversible drive?
•     Chain speed (we can make appropriate recommendations if it exceeds 1m/s)
•     Is the chain lubricated or dry running?
  
•     Continuous or intermittent operation?
•       Do you expect dirt to accumulate on the chain (scales, wood chips, bore chips) which might accelerate wear on plastics?
  
•     Is the tensioner subject to temperatures above 60°C?
•     Chemical influences
