The purpose of a NOK Oil Seal TC is to prevent the leakage of fluids, such as oil or grease, from a rotating shaft or axle. The seal is typically installed in a housing or a bore, and it fits tightly around the rotating shaft to create a barrier that prevents the fluid from escaping.
NOK Oil Seal TCs are designed to be durable and long-lasting, and they are capable of withstanding high pressures and temperatures. They are commonly used in a wide range of applications, such as automotive engines, industrial machinery, and agricultural equipment.
