<strong>Flange</strong>-<strong>Couplings</strong> <strong>RFK</strong><br />
<strong>with</strong> <strong>backlash</strong> <strong>free</strong> <strong>cone</strong>-clamping-connection<br />
E06.020e<br />
Applications<br />
A rigid and easy to disassemble shaft coupling<br />
solution for:<br />
• Various types of elevators<br />
• Conveyor pulley drives<br />
• Bucket wheel excavators<br />
• Escalators and moving walkways<br />
• Many other applications<br />
Advantages<br />
• Backlash <strong>free</strong> due to keyless<br />
<strong>cone</strong>-clamping-connection<br />
• Stronger connection than traditional<br />
“keyed” connections<br />
• No fretting corrosion<br />
• Reduced axial space required for<br />
installations<br />
• Fast disassembly for minimal downtime<br />
• <strong>Flange</strong> dimensions made to German RAG<br />
standard<br />
• Proven solution in many applications<br />

Selection<br />
<strong>RINGSPANN</strong> will select the proper coup ling for<br />
each application based upon the allowed transmissible<br />
torque under existing bending moment<br />
conditions. <strong>RINGSPANN</strong>’s selection calculations<br />
are in accordance <strong>with</strong> the latest scientific<br />
knowledge and know how in the indu stry<br />
and include the proper safety factor to prevent<br />
fretting corrosion.
