A new line of large bore couplings was recently introduced by Stafford Manufacturing Corp. 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 1" to 5" I.D sizes, the keyways are machined to customer specifications. Available in steel, stainless steel, or aluminum, Stafford Dual-Keyed couplings come with straight- or stepped bores to join dissimilar shafts. Stafford Dual-Keyed couplings are priced according to material, size, and quantity. Price quotations are provided upon request.
