Segmental rims are made of special steel plate material and heat treated to high hardness levels to achieve long service life. All elevator service segmental rim sprocket teeth are hardened to a 50 Rc minimum hardness level. This high hardness resists abrasive wear common in elevator operation. Consult the U.S. Tsubaki Engineering Department when material being conveyed is cement, ash, or other high MOHS hardness material. Special sprocket tooth hardness is necessary to resist wear from such hard abradants.
