R & D Flexible Drive Plates

We can also supply a wide range of damper plates to replace existing flexy plates or spring drive plates.

We can match a suitable plate against an existing part number, found on the outer rim of the flexy plate, or against accurate dimension of your spring plate.

We would then require: Gearbox type - O.D. of plate - numer of fixing holes and the P.C.D of the fixing holes.
