The DBH 8309 is a radial shaft seal that keeps oil or grease contained in rotating assemblies. It fits a shaft of 80 mm and a housing bore of 130.2 mm, with a height of 12.00/20.00 mm. The A 059 configuration defines a specific lip and case arrangement for sealing in dynamic conditions. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

This seal carries part number 8309 and belongs to the DBH line. Its key measurements are shaft 80 mm, housing 130.2 mm, and height 12.00/20.00 mm. The A 059 design refers to the lip and outer case style, which is built to maintain a barrier as the shaft turns. It is intended as a direct replacement where those dimensions are required, without modification.

Seals like the DBH 8309 are common in gearboxes, pumps, electric motors, drive shafts, and general industrial machinery. They keep lubricant in and keep dust, water, and particles out. In plants where oil is present, selecting the correct seal helps protect bearings and gears and reduces unplanned maintenance.

During installation, make sure the shaft and housing are clean and free of burrs. Apply the same oil or grease used in the equipment to the lip before pressing the seal in. The height range of 12.00/20.00 mm means the housing depth can vary within that span, so check that the seal seats properly. If the shaft is worn, evaluate a repair sleeve or a different size.

If you need a cross-reference, send the part number 8309 or the shaft and housing dimensions. MR Industrial Accessories can look for alternatives within the same brand or from other lines we carry.
