Typical modifications include: Hub-Alloy® castings. • Housing modifications Hub-Alloy® is a cast ferrous material this is manufactured in a carefully controlled process to produce properties • Special grease types exceeding the specifications listed below. Hub-Alloy® can be used to replace malleable iron or ductile iron. • Dust caps It is recommended for severe applications where the stronger material is required to withstand heavy loads • Auxiliary anti-rotation devices imposed on the housing. Hub-Alloy® has tensile strength properties in the range 50-65,000 psi, yield strength in • Custom bearing units with special housings and/or the range 32-45,000 psi, and elongation in the range bearings 10-12%. Specific properties of particular housings vary according to the configuration of the housing. Modified or special units may be subject to increased lead time and minimum production order quantities. Cast iron housings meet or exceed the requirements of SAE G3000 gray iron. Typical tensile strength is 30,000 psi.
