Great Lakes Forge produces hubs, spindles, and stepshafts in stainless, carbon, and alloy steels. These shapes can help your company save money over product machined out of bar stock and also give you a better part. Take advantage of our competitive in-house machine shop and heat treat facility to save on secondary operations. When viewed side by side it is hard to distinguish between a forging and one turned out of bar stock, but the intrinsic advantages of a forging are evident. Some advantages of our forged hubs, spindles, and forged steel shafts over bar stock are: Greater strength & fatigue resistance Improved microstructure Reduced downtime because of premature failures Less chance of voids with a 3 to 1 minimum reduction Continuous grain flow Longer life Able to run higher pressures and loads Reduced weight, thus saving on shipping costs

Great Lakes Forge can produce forged steel shafts weighing up to 6, 000 lbs. Our steel forging lead times are the best in the industry, often 2-3 times faster than our larger competitors. As a smaller forging facility, we have greater flexibility in our production, which helps make our fast turnarounds possible. In addition, due to forged steel's superior characteristics, the forged steel shafts we create are of far higher quality than shafts machined from bar stock. Our forged steel shafts are created from sound-center billet which is superior to bar stock in numerous ways including: Increased Strength Greater Ductility Better Resistance to Fatigue Since our base material is better quality than that of stock, our customers receive better quality forged steel shafts. At Great Lakes Forge we have the inventory and the capabilities to create forged steel shafts with carbon & alloy steels at maximum size capacities including: 1045 4140 4150 4340 We can also create forge steel shafts in smaller sizes in any of the over 200 materials we work with, including multiple grades of stainless steel.
