Unlike the traditional three piece units (RFN 4071) this new RFN 4171 Shrink Disc® employs a single long shallow taper for optimum centering. The result is better concentricity of the locking device, which makes this Shrink Disc especially suitable for high speed applications where balance is critical. (read more)
