Fostex Model 80 reel bearings they are first inspected for

they are first inspected for wear and discarded if no good (  I have no say in this and have given the lap shop a free hand here) if it looks like they will lap ok they will be tested electrically then if thats ok they will be relapped

one is for the regular smaller 1/4 inch machines

Because of size goes as a packet

its noted that on the mounting bracket they had two sets of holes so it was a planned change

again becoming a rare board

Fostex Model 80 reel bearings they are first inspected forIn the Model 80 they used these bearings, over time they will wear, these cam from a low use home machine, I would add a liitle light oil on them from time to time.
