Revox Tape Reel Motor Bellville Thrust Washers - Small type
Nagravox
Revox & Studer 1/4" REEL Motor SMALL Bellville / Thrust washers /pair.
Part No. REVOX Reel BELLVILLE small. OD = 15.6mm ID nom = 8mm
Fits most Revox reel motors in A77, B77, PR99, A700 and C270 plus some Studer models eg B67. This washer is smaller that the capstan washer and fits early reel motors (Two types). It is NOT for later reel motors which is the same as teh capstan. This part is for a pair sufficient for one motor (1.021.200). Usually you need a pair but some older motors (1.077.280) use 2 pairs (back to back per motor) ie 4 washers. The washers fits both early and later type 1 motors. If your motors rumble louder than they should after replacing a bearing, we have found usually the bellville washers have no more spring (slight concave shape) in them or are worn down. Please check to see if your motor has one pair or two by checking its part number. Later motors also have a non removable shaft lock clip on the bottom similar to the capstan motor shaft lock. (Do not remove this shaft lock clip on reel motors!)
These are suitable for most 1/4" Revox and Studer tape recorders. The washers are slightly different in appearance that some of the old originals but do the same job of pre-loading the whole bearing / shaft assembly so that it is not too tight or loose.
