The DBH 9252/85 oil seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 15.70 mm shaft diameter, 42.10 mm housing bore and a stepped height of 3.30/10.00 mm make it suitable for tight axial spaces where a firm contact lip is required. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with oil or grease. MR Accesorios Industriales supplies it as part of its seals and oil seals line.

This oil seal corresponds to the DBH designation 9252/85, with an A 119 design. Its dimensions are 15.70 mm shaft diameter (d), 42.10 mm housing bore diameter (D) and a total height of 3.30/10.00 mm (h). That stepped height combines a thin sealing lip with a thicker body, allowing it to be mounted in shallow housings without losing stability. The contact lip is reinforced with a steel spring, and the outer elastomer ensures static sealing against the housing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all cases, its function is twofold: to prevent oil or grease leaks to the outside and to block the entry of dust, water or particles that accelerate wear on bearings and gears. Because of its compact size, it is common in equipment where axial space is limited and reliable sealing is required at moderate speeds.

To correctly select this oil seal, verify that the shaft diameter is within the recommended tolerance and that the contact surface has a suitable roughness, typically between 0.2 and 0.8 µm Ra. The housing must be clean, free of burrs and have an entry chamfer that facilitates installation without damaging the lip. During installation, lubricate the lip with the same oil or grease used in the equipment and avoid striking or inverting it. If the shaft shows wear, consider a neighboring size or an oil seal with an auxiliary lip.

If you need an equivalent or a close size, the most practical approach is to send us the part number 9252/85 along with the shaft and housing dimensions. You can also indicate the type of equipment, the fluid to be retained and the operating conditions. With that data, at MR Accesorios Industriales we check alternatives within the DBH line or other brands we supply, always respecting the critical dimensions so as not to compromise sealing.
