COVID-19 (Coronavirus) update: Whilst we are continuing to ship customer orders, same day dispatch is not guaranteed. Lead times for out of stock / back order and non-stocked items are increasing due to our suppliers operating with reduced staffing levels. International deliveries - please allow extra time for your order to arrive with delays in the transport network worldwide. Some countries have suspended their internal postal system so please check with your local postal service before ordering. Royal Mail is unable to guarantee its by 1pm UK service.
You mentioned earlier that the "calculator" function for belt length/pulley centres was to be reinstated last week. Am I missing it somewhere. If this is an algorithm and you posted that, I could take it from there.
We did and we have tried but for some unknown reason the code will not work on our new site. We have passed this on to our software support team to resolve. In the meantime, we have protected access to the old website and can check for you. If you advise the pulley teeth, pitch and belt we will let you know.
We do not say it can be enlarged to any required size but that it can be enlarged to suit individual requirements. Naturally that is constrained by the boss size, if you look at the photo, you should be able to see that a 8mm hole would take away most of the boss.
We supply hundreds of different pulleys and thus not bale to stock these in anything other than with a standard bore size.
We do not offer a custom bore service for the MFA pulleys but we do for the Synchroflex T5x10m pulley, look at those and the dimensions to work out what the maximum size bore you can have.
