The TROSTEL 2.875x4.500x0.469 M/L Leather Oil Seal is engineered for industrial rotating equipment requiring durable sealing performance and traditional leather sealing technology.

The M/L Profile combines a reinforced steel outer case with a genuine leather sealing lip. This classic sealing design has been widely used for decades in industrial machinery, pumps, agricultural equipment, compressors, mining machinery, and power transmission systems because of its exceptional durability and ability to conform naturally to shaft surfaces.

Unlike synthetic rubber oil seals, genuine leather absorbs lubricating oil and develops a natural lubrication film between the sealing lip and shaft surface. This self-lubricating characteristic reduces friction, minimizes wear, and helps maintain sealing efficiency during long-term operation.

Leather oil seals are particularly suitable for machinery originally designed with leather sealing technology and for equipment operating in dusty, dirty, or poorly lubricated environments. They are also highly preferred for restoration projects where maintaining original equipment specifications is important.

The reinforced steel case provides dimensional stability and secure housing retention, while the leather sealing element offers effective lubricant retention and protection against contamination. The design is well suited for oil and grease lubrication systems used in industrial rotating machinery.

With dimensions of 2.875 x 4.500 x 0.469 inch, this seal is commonly used in industrial gearboxes, pumps, agricultural machinery, compressors, mining equipment, conveyor drives, and OEM rotating equipment utilizing inch-size shaft systems.
