The DBH 9875 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Due to its compact dimensions, it is used in gearboxes, pumps, electric motors and transmission equipment operating at moderate speeds. MR Accesorios Industriales carries this brand and advises you so you choose the correct oil seal according to the shaft, housing and type of service.

This item is a radial shaft seal from the DBH brand, identified with code 9875. Its dimensions are 43.00 mm shaft diameter, 52.00 mm housing diameter and 6.50 mm height. The Lx design corresponds to a single-lip configuration with a spring, suitable for lubricated rotating shafts. The flexible lip rests on the shaft and creates a dynamic seal; the outer body is press-fitted into the bore. The manufacturer's nomenclature makes it quick to locate in the catalog and compare with other alternatives in the same category.

Typical applications for an oil seal of this size include gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt- or chain-driven transmission equipment. It is also found in machine tools, industrial washing equipment and hydraulic systems where oil or grease must be contained and lubricant contamination prevented. In all cases, the oil seal works as a barrier between two environments and its performance depends on the correct combination with the shaft and housing.

To install a radial shaft seal, verify that the shaft is within the recommended tolerance, free of burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The housing must have an entry chamfer and a ground surface to avoid deformation. The 6.50 mm height determines the bore depth: if space is limited, a lower-height oil seal may be necessary. Peripheral speed and working temperature also influence the selection of the lip compound.

If you need an equivalent or a nearby size, send us code 9875 along with the shaft, housing and height dimensions, and the type of fluid to be retained. With that data we can look for an alternative from the same brand or from another brand we carry. If space allows, it can sometimes be replaced by an oil seal of a different height or by a design with an additional lip for greater dust protection. We can also advise you on installation and permissible tolerances.
