Rotor

A cast grey iron brake system component that operates in conjunction with the wheels. When the brake is applied, the caliper is actuated forcing the friction material against the spinning disc imparting a braking force.

Drums

Cast iron housing bolted to the wheel that rotates around the brake shoes. When the shoes are expanded, they rub against the machined inner surface of the brake drum and exert a braking effect upon the wheel to slow or stop the vehicle. These are mainly used in the rear wheels of certain vehicles.

Hubs and Assemblies

Hubs are devices that provide the mechanical connection between the wheels, rotors/discs, and drums to the bearings mounted on the axle's axis of rotation. They are made of various materials including steel, aluminum, and cast iron. Hubs transmit vertical, lateral, and fore-aft forces as well as braking torque to the vehicle. They often contain the lubricant and seals for the wheel bearings. For driven axles they transmit the engine torque to the road via the wheels.

Other products

In Rassini’s foundry some other products are manufactured such as motor balancers, clutch plates, spacers and for the tractor industry the wheel hubs and counterweights for tractors are produced.
