Rolling is the name given to the process of passing metals between two rollers and thinning them. If the roller bearings are made of bronze, brass and similar metals, the counter surface metal wears out over time and the bearing needs to be replaced. This is also a costly process. Ali Şirin Makina, on the other hand, provides a great advantage in this field of application, as rolling bearings are more durable and cheaper than steel, brass and other metals. Conventional hot rolling, industrially applied in steelmaking, plays an important role in turning many types of steel into plates, sheets, or profiles, from low-carbon or plain-carbon steels to high-alloy steels. Today, the conventional rolling method can be gradually controlled much more precisely, and when the process is completed, low-alloyed high-strength fine-structured steel compositions that will provide the desired mechanical properties can be achieved. Among the products we produce; There are rolling bearings, rollers used in the production of flat products (rolling roller, hypolan coated roller, polyurethane coated roller, etc.), roller bearings, rack gears, chain gears, equipment used in the production of flat products.
