The TROSTEL 1.688x2.285x0.500 M/L Leather Oil Seal is engineered for industrial rotating equipment requiring durable sealing performance and traditional leather sealing technology. It is particularly suitable for heavy-duty industrial machinery, agricultural equipment, mining machinery, restoration projects, and OEM equipment originally designed with leather oil seals.

The M/L Profile combines a reinforced steel outer case with a genuine leather sealing lip, creating a proven sealing solution that has been widely used in industrial rotating machinery for decades. The robust construction ensures excellent dimensional stability while providing consistent sealing performance throughout extended operating periods.

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

Leather sealing lips also provide excellent shaft conformity, allowing the seal to compensate for minor shaft wear and surface imperfections. This makes M/L leather seals particularly valuable for restoration projects and older industrial equipment where maintaining original equipment specifications is important.

Manufactured using premium Genuine Leather and a reinforced steel case, this seal performs exceptionally well in dusty, muddy, and contaminated environments where conventional rubber seals may experience accelerated wear.

With dimensions of 1.688 × 2.285 × 0.500 inch, this oil seal is commonly installed in industrial pumps, heavy-duty gearboxes, agricultural machinery, mining equipment, compressors, conveyor systems, power transmission equipment, and OEM machinery utilizing inch-size shaft systems.
