Crankshafts
We are a leading supplier of crankshaft steels to forging customers in North America. Our material science and technology advancements created a family of high strength, low alloy automotive steels, TimkenSteel MicroTec® grades. These automotive steel grades create cost savings by eliminating post-forged heat treatment and enhanced machinability while still delivering the needed strength, ductility and fatigue characteristics specified by the customer.
Gears
A leading supplier of value-added automotive steel products for gear components, we continue developing enhanced processing and supply chains from steelmaking through gear cutting preparation. A result of this work is our family of VacTec™ vacuum carburizing automotive steels. They provide improved heat-treat properties, including the minimized distortion and uniform microstructure that automotive manufacturers value.
We are your source for automotive gear steel, with a century of experience producing clean, high-quality steel for the gears industry. Cleaner steel in gears equates to better fatigue resistance, generally improving life, reducing bending and sliding fatigue issues, and decreasing cracking and chipping. Clean steel also helps you meet or exceed your design criteria. You could put greater load through gears, reduce your manufacturing costs and distortion – and improve customer satisfaction.
Bearing Hubs
Front-wheel, rear-wheel and all-wheel drive units require power transfer to vehicle wheel ends. Bearing hubs are the final components where mechanical energy flows to wheel and tire assemblies. High-performance clean steel enables this critical transfer. TimkenSteel has played an integral part in advancing bearing hub technology, supporting customers with optimum clean steel technology for bearing hub load requirements and integrated bearing designs.
Continuous Variable Transmission (CVT) Components
Continuous variable transmissions (CVTs) are gaining in share and have full-efficiency benefits. Pulley and gear applications are two critical CVT components. Along with investments to produce the sizes that CVT components require, we apply our materials and manufacturing know-how to pulley applications that meet tough requirements. For CVT gear applications, we have a rich expertise and history supplying these components with high-performance quality.
Axles
TimkenSteel seamless mechanical tubing is a product of choice for light truck and critical axle applications.
Constant Velocity Joint Components
We are a leading provider of constant velocity joint components for front-wheel driveline assemblies. Precise control of chemistry, dimensional tolerance and surface quality are critical in the manufacture of these critical load-bearing components. Our automotive steelmaking and supply chain expertise enables an efficient solution – including our assets and subcontractor operations.
Shafts
In planetary gear sets, everything revolves around shafts that support the gears. Shafts are a vital element in the power transmission system. Along with investments to produce the sizes that shafts require, we apply our materials and manufacturing expertise to planetary shafts that turn with less friction and wear.
Fuel System Components
Fuel distribution and fuel injection designs are experiencing significant technology changes, undergoing cyclical loading with significantly higher pressures. This demanding environment requires ultra-clean steel to perform reliably. Our high-performance automotive steel meets these specifications.
