Fostex B16 E16 speed sensor striped guide roller This is the back bush

This is the back bush that sits between the reel table and the motor

In old machines this grease dries out so the drum unit  gets stuck and springs fall out etc etc

To fit just cut of the old tyre clean the bush or bearing and then squeeze these on the a very high tolerance so can hug the old unit

These are the group pcbs used in the Tascam M2600 they are each individually made rather than making a common pcb and just adding links

if you have one of these its worth having an extra channel or two that you can just drop and swap if needed
