flat belt for e. g. BL 91
belts are an exact copy of the original ones. All measurements and parameters
"Only" better material has been used because it keeps it´s
characteristics for a longer period of time. Although it is recommended
to replace the belt every second year when running the turntable on
an average level!
This belt is precisely grinded double-sided which gives you the possibility
to run it on both sides without risking wow and flutter.
Parameters like slippage, elasticity (if too inelastic,
then, by the time you´ll risk damages of your motor and platter
bearings because of the effect of too high tractive forces) and
grip (no gliding when turning on - avoids wear of friction!)
