The DBH 8491 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 29.85 mm shaft diameter, 47.00 mm housing and 11.30 mm height make it suitable for gearboxes, pumps and electric motors. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.
This item is a radial shaft seal from the DBH line, identified with the part number 8491. Its dimensions are 29.85 mm shaft diameter (d), 47.00 mm housing diameter (D) and 11.30 mm height (h). The A 075-Bidi design indicates a double-lip configuration, intended to improve sealing in both directions. It is made of elastomer with a metal reinforcement, although the manufacturer's product page confirms the exact compound.
Typical applications of this seal include gearboxes, centrifugal pumps, electric motors and power transmission equipment. In these systems, the seal prevents oil or grease leaks and blocks the entry of dust, water or particles. It is commonly found on 29.85 mm shafts where reliable sealing is needed at moderate speeds and normal operating temperatures.
To mount it correctly, check that the shaft and the housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The selection must consider peripheral speed, temperature and the chemical compatibility of the fluid. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. The A 075-Bidi designation gives guidance on the type of lip, but always confirm with the technical data sheet.
