There are four basic centrifugal clutch and brake design options available from Suco.
The "F" type (self increasing clutch).
This compact and self increasing clutch allows the transmission of high torques whilst needing little space. The profiled hub has a special form which causes a wedging effect between the profile and the flyweights when torque is applied to the clutch. This results in an additional force on the linings and allows higher torque to be transmitted. The tension springs and linings are easily accessible for replacement.
The "S" type (Pin-guided clutch with 3 flyweights)
In contrast to the F-type clutches, the linings of pin-guided clutches are permanently bonded to the flyweights instead of being mounted on loose carriers. The guide pins of W-type clutches provide accurate guidance for the flyweights, which ensures quiet operation of the clutch.
The "W" type (pin-guided clutch with two flyweights)
The "W" type combines the advantages of the F-Type and S-Type centrifugal clutches and Brakes. The tension springs and linings are easily accessible for replacement if worn. As with the "S" type the guide pins provide accurate guidance for the flyweights, which ensures quiet operation of the clutch.
The "P" type (asymmetric pivot clutch)
This design is extremely narrow and the quietest running centrifugal clutch in the Suco range.
