These shaft couplings have a high speed range, and a large angle of twist with a progressive characteristic curve, approximately 6-8º at nominal torque.
High elasticity and considerable flexibility in any direction with low counter forces on shafts and bearings ensures the shafts do not need to be aligned accurately.
The action of Centaflex-A couplings are shock and vibration absorbing, with torque transmitted absolutely free from play, uniformly and electrically insulated.
Rubber parts suffer no wear, so no maintenance is required, providing long useful life with no dirt produced by rubber particles.
The rubber element is air flushed all around, and can easily be fitted and dismantled without the use of special tools or tension bands. Heat generated is easily conducted away, keeping the rubber element cool.
Rubber elements are supplied in various shore hardness grades, permitting torsional stiffness to be varied within wide limits.
These shaft couplings can be very easily aligned, relying only on line of sight or the aid of a straight edge, without the need for any special templates or gauges.
