Driven Plate Material Types

Sintered:-
A thin layer of metallic friction material which is sintered directly onto a steel disc. Normally for circuit use only.



Bonded Paddle:- (New Product)
Direct sintered material offering increased friction surface area. Bonded Cerametallic now replace the original riveted type.

Driven Plate Design

Sintered Solid Back to Back:-
Available in sizes Ø115, Ø140, and Ø184mm. Versions are available with extended nose to increase spline length.

Sintered Paddle Back to Back:-
Available in size Ø184mm. Recommended for use in high torque applications when using a single plate Ø184mm sintered clutch.

Gear Driven:-
Designed to provide increased flywheel / crankshaft fixing bolt clearance and maximum spline length. Available in Ø140 and Ø184mm in either 2, 3 or 4 plate versions. Recommended where a high level of engine vibration or input shaft runout can be expected.


Nested Types:-

Allows for extra flywheel / crankshaft fixing bolt clearance. Available for Ø184mm clutches only.

Bonded Paddle:- (New Product)
 
3 paddle available for Ø140mm (5½") & Ø184mm (7¼") 4 paddle available for Ø184mm (7¼") clutches only.

Rigid Cerametallic:-

Available in 4 and 6 paddle configurations for Ø200mm (8") and Ø215mm (8½") clutches.


Spring Centre Cerametallic:-
These plates are available in 4 or 6 paddle configurations and use a sprung centre hub with damper springs to reduce the torsional vibrations in the drive line. Available for Ø200 and Ø215mm clutches.

Driven Plate Thickness and Wear In.
The total allowable driven plate wear will vary according to the "wear in" and the number of driven plates for each particular clutch. For example, for a 3 plate clutch with 0.75mm "wear in" each plate can wear 0.75mm/3 = 0.25mm from new.

The minimum worn driven plate thickness given in this catalogue assumes even wear across all plates. However it is permissible to to run plates below this thickness provided the total wear does not exceed the "wear in" figure.
