The RECCA17B shaft locking assemblies consist of a taper inner ring with a clamping bolt and an outer ring. The outer ring is tightened against the inner ring by tightening the clamping bolt. These shaft locking elements use a single lock nut to apply clamping pressure, allowing for quick assembly and disassembly. The lock nut can be held in position by bending the tabs of the lock washers. The combination of the thin wall of the clamping cone and low wheel pressure allows for use with soft materials (such as aluminum) and small wheel diameters.
Aligning the hub to the center of the shaft
Due to its size, this clamping element is ideal for short-cycle installation.
Easy mounting by means of clamping nuts
Designed for shafts from 15mm to 70mm in diameter.

Recca shaft hub connection offers the latest in transmission connection technology.
Recca Keyless Locking assemblies 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 a 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.
