This single-lip radial seal carries the dimensions 82.55 mm shaft, 122.24 mm housing bore and 12.70 mm height, and it fits equipment where leak control matters. Our team can help you confirm that this is the right seal for your machine.

The reference 6540 belongs to the DBH line of radial shaft seals. Reading the size in the usual order, the seal is built for a shaft of 82.55 mm, a housing bore of 122.24 mm and a height of 12.70 mm. The A 094 design uses one sealing lip with a spring, a configuration intended for rotating shafts running at moderate peripheral speeds. The elastomer lip handles oils and greases, and the metal case holds the seal firmly in its bore.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission assemblies. In each case its job is the same: keep lubricant where it belongs and keep dust, water and particles out. Because a worn seal can lead to premature wear of bearings and gears, plus unplanned downtime, it is a part maintenance teams watch closely.

Installation calls for a shaft with suitable surface hardness and controlled roughness, since a finish that is too rough will wear the lip faster. The housing should be clean, free of burrs and machined to the recommended tolerance for radial shaft seals. Lubricate the lip before pressing the seal in, and use an installation tool that will not damage it. If the shaft shows a groove or wear, consider a seal with an offset lip or a repair sleeve.
