A precondition for the proper functioning of sprocket wheels, bevel gears, spur gears, worm gears etc. is the accuracy of the tooth system and the concentricity relative to the location hole. This is ensured by the manufacturing procedure selected for off-the-shelf standard parts.
Sprocket wheels with one-sided hub
Atlanta sprocket wheels with one-sided hub are made of normalized heat-treatable steel C45 (material no. 1.0503) with a strength of 600 - 700 N/mm². If higher strength is required, these wheels can be quenched and tempered or else the teeth can be fame or induction hardened (to approx. 50 RC).
Plate-type sprocket wheels
Atlanta solid plate wheels are made of sheet with a strength of 500–600 N/mm² unhardened. Due to the larger diameter condition, they are usually not subjected to heat treatment. Induction-hardening or fame-hardening to approx. 50 HRC is only possible after case-hardening.
