New Product: Stainless-Steel Couplings

The 17-4PH stainless-steel couplings offer higher torque capacity and torsional stiffness with two sets of flexures for increased parallel offset.

Three series are available: the W Series (metric) accommodates shaft sizes from 3 to 20 mm, the MC Series from 0.16 to 1.75 in., and the H Series from 0.06 to 0.75 in. All three series are capable of transmitting torque through 5° if required and can operate in temperatures up to 600°F (300°C).
