Idler lengths

The diameters and lengths of idlers for bulk material conveyors are standardized*. 
The most important standards for this are DIN 22107, DIN 15207-1, ISO 1537-1975 and DIN 22112-1.

Here you will get the overview of the according to DIN 22107 standardized designs of bulk material idlers from our standard delivery program*. This standard shows the relationship between belt width, idler diameter and idler length for idler stations with idlers of equal length with up to three idlers per station.

DIN 15207-1 includes significantly more idler lengths that are only related to idler diameter.

*In addition, we are happy to offer other designs according to your specific requirements. Please feel free to send us a request.
