The DBH 9741 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 12.70 mm shaft, 25.35 mm housing and 6.40 mm height, and an Mx design, it is press-fitted into the housing and runs against the rotating shaft. It is a key part in compact-size gearboxes, pumps and electric motors, where space is limited and sealing is critical to prevent leaks and premature wear.

This item is a radial shaft seal from the DBH brand, identified with code 9741. Its dimensions are 12.70 mm shaft diameter, 25.35 mm housing diameter and 6.40 mm height. The Mx design corresponds to a standard single-lip configuration with spring, suitable for rotating shafts at moderate speeds. The sealing lip, generally made of elastomer, ensures dynamic contact against the shaft, while the outer body secures the anchoring in the housing. It is a common replacement part in equipment where oil or grease containment is required.

Typical applications of this seal include speed reducers, small centrifugal pumps, low-power electric motors, compressors and transmission boxes. It is also used in agricultural machinery, material handling equipment and centralized lubrication systems. In all cases, its function is to prevent lubricant leakage and the ingress of dust, water or particles, extending the service life of bearings and gears. It is frequently found on fan, mixer and belt conveyor shafts.

For correct installation, verify that the shaft has a smooth surface free of burrs, with adequate hardness and roughness. Lubricate the lip before inserting it and use an installation tool that presses on the outer diameter, never on the lip. Shaft and housing eccentricity must be minimal to avoid irregular wear. When selecting a seal, consider peripheral speed, operating temperature and the chemical compatibility of the elastomer with the fluid to be retained. These variables define the service life of the seal.

If you need an equivalent seal, contact us by WhatsApp. We can look for alternatives with the same shaft diameter but a different housing or height, or with another lip design. To do so, send us code 9741 or the exact dimensions and the type of application. We can also advise you on compatibility with the lubricant used and the operating conditions.
