RfN 7110 42x55 Locking Assembly
The RfN 7110-42x55 is a self-centering locking assembly without axial displacement. They feature low surface pressure used for thin-walled hubs with a low extension limit. As the locking screws are located out of the actual clamping area and the pressures are relatively low, the hub can be designed economically small. Thus they are particularly ideal for applications in narrow spaces because of the low structural height. You can download the product's 3D model below.
