J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
The hydrodynamic ribsa) have a two-stepped rib configuration provided in one direction on the air face of the lip. Even if the first rib is worn out, the second rib comes into contact with the shaft surface, meaning that this type of oil seal ensures higher sealing performance. Seal with Side Lip A large side lip ensures prevention of entry of dust/water.

am5c spark plug. Over time, deposits can accumulate on the spark plug electrodes, which can inhibit the spark and reduce engine performance. The AM5C spark plug is engineered to resist fouling, ensuring that it maintains its performance and longevity.
There are several materials used to manufacture oil seals. They are discussed below.


The sealing effect is achieved by manufacturing a smaller inside diameter than the required shaft size, which preloads the sealing lip. A garter spring is often used to ensure a constant force on the shaft.
