Product Description

SKF PHFFX51-190X250 keyless shaft bushing / locking assembly. Frictional shaft-to-hub coupling that transmits torque without a key or splined joint, by radial-elastic clamping between the shaft and hub. Executed as a double-taper collet (self-centring), a single-taper Ringfeder-style assembly, or a stepped-piston hydraulic clamp. Removed and re-installed non-destructively; excellent choice for high-precision or high-torque locations where a keyway would fatigue the shaft.
