The DBH 9285Pol oil seal is a single-lip radial shaft seal designed for rotating shafts with a diameter of 44.2 mm. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles, protecting bearings and bushings. It is press-fitted into 71.4 mm housings and accepts a height of 10.00 to 16.50 mm depending on the seat. It is a wear part that should be replaced at every teardown to prevent leaks and premature failures.

This DBH 9285Pol oil seal has a shaft diameter of 44.2 mm, a housing diameter of 71.4 mm and a height that ranges from 10.00 to 16.50 mm. Its A 103-R-H design corresponds to a spring-loaded radial lip, intended for rotating shafts at moderate speeds. The designation 9285Pol identifies the size and construction type within the DBH line. It is a sealing component that works in direct contact with the shaft and must maintain a lubricant film to avoid premature wear.

It is used in gearboxes, pumps, electric motors, transmission equipment and agricultural or industrial machinery in general. It also appears in spindles, fan shafts and conveyor systems. In all cases, its mission is to contain the oil or grease and block external contamination. When the oil seal loses elasticity or the lip is damaged, leaks appear and the bearing loses lubrication, which accelerates failure of the assembly.

To select it, verify that the shaft diameter and the housing diameter match the values indicated. The shaft must be clean, free of burrs or deep marks, and the housing must have the proper entry chamfer so as not to damage the lip during installation. Lubricate the lip with the same grease or oil used in the equipment before inserting it. If the previous oil seal has a different height, confirm that the available space accepts the 10.00 to 16.50 mm range.

If you need a nearby size or an equivalent from another brand, send us the full code and the shaft and housing measurements. We can also help you identify the oil seal from a sample or from dimensions taken with a caliper. At MR Accesorios Industriales we sell the DBH brand and have more than 80 years of experience in power transmission and sealing. Write to us on WhatsApp and we will quote the part you need.

Before replacing, check the condition of the shaft: if it shows wear in the lip area, the new oil seal will not seal properly. In that case, consider a repair sleeve or an oil seal with an offset lip. Also verify that the crankcase breather is not clogged, because internal pressure can push the seal out.
