The DBH 5901Sil oil seal is a single-lip radial seal designed for rotating shafts in industrial equipment. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. With dimensions of 95 mm shaft, 120 mm housing and 13 mm height, and an Lx design, it is press-fitted into the housing and runs on the shaft surface. It is a common replacement part in pumps, gearboxes and transmissions.

This item is a DBH radial shaft seal, identified by the code 5901Sil. Its nominal dimensions are 95.00 mm shaft diameter, 120.00 mm housing diameter and 13.00 mm height. The Lx design corresponds to a single sealing lip with spring, without an external dust lip, suitable for applications where the seal is seated in a machined bore and the shaft rotates in one direction or alternating. The lip elastomer and the internal spring ensure continuous contact on the shaft.

Typical applications for this seal include centrifugal pumps, gearboxes, electric motors, conveyor rollers and power transmission equipment. In all these cases, the 5901Sil seal performs the dynamic sealing function: it prevents oil or grease leaks and protects the bearings from contaminant ingress. It is a critical part in preventive maintenance, since timely replacement extends the service life of the assembly and reduces unplanned downtime.

To install this seal, verify that the housing and shaft are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Installation must be perpendicular to the shaft, with uniform pressure on the outer ring, never on the lip. If the shaft shows wear or grooves, consider an alternative size or a repair sleeve. Seal selection depends on the speed, temperature and type of lubricant in the equipment.

If you need a seal equivalent to the 5901Sil or a nearby size, the most practical approach is to send us the complete code, the shaft, housing and height dimensions, and a photo of the part. With that data we can search for an alternative within the DBH line or other brands we carry. We can also advise you if the Lx design is not suitable for your application and another lip type or material should be considered.
