Shaft Clamping Collar RECCA 33 – RFN7014 HIGH TOQUE SOLLUTION


The long, flat cones allow for maximum torque and/or axial force, transferred with shaft clamping collar RECCA 33. The Multiple parts construction allows for the shaft clamping element, shaft and hub remain in the same position during the assembly process and there is no axial movement. The shaft and hub only need to be pressurized, ensuring a higher level of safety than the three-piece version.

shaft clamping collars RECCA 33 can be interchanged with RINGFEDER RfN 7014. It has features of self-centering and low surface pressure.

What is a Recca Shaft Clamping Collar?

Recca Shaft Clamping Collar offers the latest in transmission connection technology.

Recca Keyless Locking collars connect all types of drives to their respective shafts by means of frictional forces for torque and axial thrust load transmission. Precision tapered thrust cones within the clamping element create high pressure between the shaft and hub to securely hold pulleys, sprockets, gears, etc. The stresses on the hub and shaft are similar to a heavy pressure fit, but the actual stresses are easy to calculate, and the hub can always be easily removed without damage to the shaft. All you need for assembly and disassembly is a torque wrench.

The shaft clamping element allows backlash-free precision torque transmission without the need for strict manufacturing tolerances of the mating parts. The simplified design results in reduced manufacturing costs and is easy to assemble and disassemble.
