Re: Pulley Lagging - Wear Of Rubber
Dear Mr.Roland Heilmann,
We may need to measure the hardness of the lagging. If the hardness is increased after certain value, the grip between the drive pulley lagging and the conveyor bottom cover will be reduced. Pulleys lagging will also look more polished.
And it will start slipping.
Hope others may throw more light on this issue.

In a few days we will have attached to our website below a paper on transitions that you need to read. Lagging wear on pulleys is usually not an issue of the rubber quality but of the system installation

Is this a multiple drive application?
If so, regarding the allowable limit, the answer may be driven by load sharing.

How To Proceed
Dear collegues,
thank you for your ideas & input.
@ Lyle: Yes, in a specific case now investigated there is a conveyor with two driven pulleys, the drive pulley diameters are currently mesured up to know numbers at last, but in the past the lower pulley did (in all likelyhood because i couldn't check that) show increased wear. However, before proposing ceramic lagging (which i preferred from the beginning of the investigation) i wanted to back up on commonly used limits on wear. Your hint on load sharing is very much correct.
Concluding: Point of interest is Load sharing by regulating the fill of the constant fill fl. cplgs with notion of wear on pulley lagging.
Thank you once more, and with
Best regards

Pulley Lagging - Wear of Rubber
Dear Forum members,
Concerning the rubber lagging of drive pulleys, how would you professionally evaluate the amount and/or pattern of wear? When is in your opinion wear of lagging becoming unacceptable ex common limits (considering speed of wear, disbalance of pattern, ..). What would be your rule-of-thumb limit of wear if to be compared with the original lagging thickness?
Thank you in advance, &
Best regards
