Title: Where to get belt rollers? Post by: memper on March 13, 2015, 09:04:58 AM Its getting warm enough in nyc so its time to dust off, change fluids and do maintenance checks. Upon inspecting my belt roller(fixed) and tensioner bearings they seem to spin ok with my thumb but they have patches of rust on them.
Should I just run them if they spin ok and the rust will be worn off by belt movement or should I replace? If replacing, where can I purchase them? *edit: it seems I can get the tensioner bearings here: https://www.motionindustries.com/productDetail.jsp?sku=02137990 (https://www.motionindustries.com/productDetail.jsp?sku=02137990) But where for the fixed roller bearing? Part number? Title: Re: Where to get belt rollers? Post by: ducpainter on March 13, 2015, 11:41:25 AM If they spin smoothly just run them. The rust will polish off.

Title: Re: Where to get belt rollers? Post by: memper on March 20, 2015, 10:23:58 AM I checked McMaster. The longest roller they have in metric Permasealed is 14mm. But mine spin ok so the belt movement will likely clean them up.

I do think it may be beneficial to change the other (cheap) bearings, especially if they are getting up there. If one seizes up it'll wear your belts prematurely. And new rollers look aesthetically pleasing...my Nachis are a trick red color.
