279585
Used in Dual Models (without guarantee):
CS750, CS750-1, CS5000, Golden 1, Golden Stone, Silver Stone
Description:
The Dual models, listed above, are very sensitive regarding belt tension and belt material. Therefore we created a belt with dimensions very near to the original Dual dimensions. This is not the case for most of the available replica belts. The belt width is 4mm only, like the original belt. The belt diameter is choosen in a way, that the belt sits just with minor tension at the belt drive diameter of the platter. Like it was with the original Dual belt. Also the belt thickness is only 0.5mm, like the original belt. This creates very low friction losses during operation.

So this belt is the best choice, if you would like to reach the performance values as originally planned from Dual.den Stone

Substitute for Dual Part Number:

Used in Dual Models (without guarantee):
CS130, CS505, CS505-1, CS505-2, CS505-3, CS505-4, CS506-1 (not CS506!), CS508, CS522, CS528, CS1254, CS1256, CS1257, CS1268
Description:
For many years, the "origial belts" for a Dual 505-4 were produced out of the original specification. They were much thicker than the original belts in the above listed models. The belt thickness has increased to 0.8mm, which creates much higher belt tension as originally planned. This stresses the motor and platter bearing and resuls also in higher wow and flutter values.

Therefore we created our own belt replica, according to the old belt specifications from Dual. The belt thickness is back to the original 0.6mm, which makes the belt much more flexible. Belt tension is signifficantly reduced. This creates less forces to the bearings and improves the wow and flutter values as well. Also the belt switching mechanism works more reliable with this belt.

So this belt is the best choice, if you would like to reach the performance values as originally planned from Dual.
