Type 2RS - Molded rubber seal. This type of seal is Buna-N bonded to a steel insert. The seal is fixed into a groove in the outer ring. This type of seal can be removed but care must be used not to bend or cut the seal lip. Max operating temperature is 240° F. This type of seal makes contact with the inner ring providing better protection in contaminated environments than a metal shield. However, this results in an increase in torque and reduces the max speed capability of the bearing. Certain lubricants and chemicals react with rubber. The code for a single seal is RS.
