The DBH 6540 oil seal is a single-lip radial seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 82.55 mm shaft diameter, 122.24 mm housing bore and 12.70 mm height, it is used in industrial equipment where a reliable barrier against leaks is required. MR Accesorios Industriales supplies this official brand and advises you so you can choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 6540. Its standard dimensions are: shaft diameter (d) of 82.55 mm, housing bore diameter (D) of 122.24 mm and height (h) of 12.70 mm. The A 094 design corresponds to a single sealing lip with spring, suitable for rotating shafts at moderate peripheral speeds. The lip elastomer ensures sealing against oils and greases, while the metal case ensures a firm fit in the housing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the DBH 6540 seal protects bearings and gears from external contamination and prevents lubricant loss. It is a critical part in industrial maintenance, since its failure can cause premature wear of internal components and unscheduled downtime.

For correct installation, verify that the shaft has adequate surface hardness and controlled roughness; a finish that is too rough accelerates lip wear. The housing must be clean, free of burrs and with the recommended tolerance for radial shaft seals. Lubricate the lip before inserting it and use an installation tool that avoids damaging the seal. If the shaft has a groove or wear, evaluate the possibility of using a seal with an offset lip or a repair sleeve.
