The TROSTEL 4.250x6.256x0.563 M/L LEATHER Oil Seal is designed for demanding industrial applications where sealing reliability, contamination protection, and long service life are critical.

The M/L Profile combines a strong metal outer case with a genuine leather sealing lip. This construction provides excellent housing stability while allowing the leather lip to maintain effective contact with the shaft surface.

Unlike conventional rubber oil seals, the genuine leather sealing lip absorbs lubricant and creates a natural lubrication film between the shaft and sealing surface. This helps reduce friction, minimize shaft wear, and improve sealing performance in dusty, abrasive, and contaminated environments.

This heavy-duty leather oil seal is especially suitable for older industrial machinery, mining equipment, agricultural equipment, conveyors, crushers, pumps, and imported machinery using inch-size shafts.

Manufactured with a durable metal case and genuine leather lip, the TROSTEL M/L seal helps prevent oil leakage, protect bearings from contamination, reduce downtime, and extend equipment service life.
