MR Accesorios Industriales sells this 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 by part number 8491. Its dimensions are 29.85 mm shaft diameter (d), 47.00 mm housing bore 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 data sheet confirms the exact compound.

Typical applications for 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.

For correct installation, check that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Selection must consider peripheral speed, temperature and chemical compatibility of the fluid. If the shaft shows wear, evaluate a seal with an auxiliary lip. The A 075-Bidi designation indicates the lip type, but always confirm with the technical data sheet.
