The SKF flex couplings are designed to accommodate misalignment and shock loads and dampen vibration levels. It is easy to install, maintenance-free couplings are available with either a machined-to-size or tapered bore. These couplings are also available with a taper bushing and it consist of 2 flanges and 1 tyre. The flanges are phosphate coated for improved corrosion resistance. The addition of a standard sized spacer flange can be used to accommodate applications where it is advantageous to move either shaft axially without disturbing either driving or driven machines.
