We offer high efficient cast iron hubs under the name OD 380 Cast iron hub with PB material. These hubs are extensively used along with worm gears, which are also known as worm reduction gears. To construct superior grade of hubs, we use precisely extracted PB2 materials. The larger size cast iron hubs are useful in those application in which extra strength is required. Our experts develop the design specification of these hubs by using cutting edge technologies, which enable these to become cost effective. Aluminum is the best alternative material of cast iron to construct these hubs.
