The DBH 9143 radial shaft seal is a lip seal designed to retain lubricant and prevent contaminants from entering rotating shafts. Its dimensions of 33 mm shaft diameter, 56 mm housing diameter and 12 mm height make it suitable for gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified by part number 9143. Its dimensions are 33 mm shaft diameter (d), 56 mm housing diameter (D) and 12.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and spring, intended for rotating shafts with lubrication. The elastomeric lip presses against the shaft and the spring maintains contact pressure to compensate for wear. The outer metal case ensures a firm fit in the housing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, its function is to retain oil or grease inside the assembly and block dust, water or particles that could damage the bearings. It is a wear part that should be replaced when leaks or abnormal noises appear in the sealing area.

To correctly install a radial shaft seal, check that the shaft has no burrs or marks and that the sealing surface is polished. Lubricate the lip with the same oil or grease used in the machine before inserting it. The seal must enter perpendicular to the housing, without blows that deform the case. If the shaft shows wear, consider an adjacent size or a seal with the lip in a different position. The selection depends on speed, temperature and the type of fluid to be retained.
