The SCHNIEDER 3.625x4.625x0.625 M/L Leather Oil Seal is engineered for rotating equipment requiring durable sealing performance and traditional leather sealing technology. It is particularly suitable for industrial machinery originally designed with leather oil seals, heavy-duty equipment, and machinery restoration projects.

The M/L Profile features a reinforced steel outer case combined with a genuine leather sealing lip. This proven design has been widely used in industrial pumps, gearboxes, compressors, agricultural machinery, mining equipment, and heavy-duty rotating systems due to its ability to provide dependable sealing even in harsh operating environments.

Unlike synthetic rubber seals, genuine leather naturally absorbs lubricating oil and creates a microscopic lubrication film between the shaft and sealing lip. This self-lubricating characteristic reduces friction, minimizes shaft wear, and extends the service life of both the seal and the rotating shaft.

Leather sealing elements also offer excellent shaft conformity, making them ideal for shafts with slight wear or surface imperfections. They perform exceptionally well in dusty, muddy, and contaminated environments where conventional rubber seals may experience accelerated wear.

The reinforced steel case provides excellent dimensional stability and secure housing retention while the leather sealing element effectively retains oil and grease, preventing contaminants from entering the equipment.

With dimensions of 3.625 × 4.625 × 0.625 inch, this oil seal is commonly installed in industrial pumps, heavy-duty gearboxes, agricultural machinery, mining equipment, compressors, conveyor systems, restoration projects, and OEM rotating equipment utilizing inch-size shaft systems.
