A new line of large bore couplings that feature axial and annular keyways for use with pumps and mixers driven by unsupported shafts is being introduced by Stafford Manufacturing Corp. out of Wilmington, Mass.

Stafford dual-keyed couplings feature axial and annular keyways to transmit torque while restraining lateral motion in pumps and mixers that are driven by unsupported shafts. Offered in one to five-inch I.D sizes, the keyways are machined to customer specifications.

Available in steel, stainless steel, or aluminum, these couplings come with straight- or stepped bores to join dissimilar shafts. They are priced according to material, size, and quantity. Price quotations are provided upon request.
