Claw clutches
Description
Claw clutches (JAW, curved jaw, RPX) are general-purpose clutches consisting of two pieces of metal hubs and one piece of plastic clutch inserts. Claw clutches are the most affordable clutch type in terms of value for money. They are relatively inexpensive, transfer large forces relative to their mass and are suitable for almost all uses. Claw clutches can be made of cast iron, aluminium or steel. We do not sell steel versions in our webshop!
Claw clutches are either made in a tapered clamp (Taper Bush) design or have a base hole. Conical clamping clutches do not include a tapered clamp but only indicate the type of tapered clamp they can be fitted with. The tapered clamping can be ordered HERE. In the case of designs with a base hole, drilling to the final size and machining the fastening (latch, thread) is the responsibility of the customer.
In the table below, Type A hubs are lighter designs with reduced outer diameter. Type B hubs are cylindrical on the outside, heavier, but can be bored larger. In the table, for type B hubs, only SIT and Sati brands are subject to the lower drilling limit. For Challenge products, the base bore of the Type B hubs is equal to the maximum rated drillability of Type A hubs with the same switch size.
A star-shaped, curved insert belongs to the claw clutches we sell. Yellow 92 ShA for normal loads, Black 94 ShA for normal loads, Red 98 ShA for heavy loads, Green 64 ShA for internal combustion engines are recommended.
The maximum parallel shaft deviation withstood by claw clutches can be 3.4mm. The maximum shaft angle that cast iron claw clutches can withstand can be 1.3 degrees. The maximum shaft deviation depends on the size of the clutch and the insert used, check the catalogue!
