- Measuring Oil Seal Dimensions
J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.

- In addition to material science, the art of skeleton oil sealing involves the skillful application and installation of these seals. Technicians must have a deep understanding of the machinery they are working on, as well as the specific requirements of each seal. Proper installation requires precise measurements, clean surfaces, and the correct tools and techniques to avoid damaging the seal or the components it protects.
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.
Select the correct oil seal size
The oil seal within the wheel hub assembly is crucial for preserving the lubrication of the wheel bearings and protecting them from premature wear and damage. Proper maintenance of the oil seal wheel hub is essential to prevent oil leakage and maintain the efficiency of the wheel assembly. Regular inspection and replacement of worn or damaged oil seals are vital to ensure the continued reliability and safety of the vehicle.
(1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, low-speed shafts should use low-speed oil seals, and low-speed oil seals cannot be used on high-speed shafts, and vice versa.
Oil seals are called rotary shaft seal or radial lip also.

mechanical oil seal. This design helps to prevent oil leakage by trapping oil within the seal and redirecting it back into the system. Labyrinth seals are commonly used in high-speed applications where traditional lip seals may fail.
Aspects to consider when selecting oil seals
Slowly raise the engine about 11 in. (38 mm) and insert wedges between the mounting rubbers and pads .
3. The spring on the lip of the oil seal tends to provide support to the lip and prevents the lubricant from leaking outside and also prevents the entry of contaminants from outside.
