The DBH 8159 is a radial shaft seal built to keep lubricant in and contaminants out where a shaft turns. It fits a 38.54 mm shaft, a 50.80 mm housing bore and an 8.00/9.90 mm height, so it works well where axial room is tight. The seal presses into the housing and rides the shaft on a thin oil film that limits friction while holding the seal. Treat it as a wear item and renew it during scheduled preventive maintenance.

This seal carries the DBH brand and part number 8159. Read the size as shaft 38.54 mm, housing 50.80 mm, width 8.00/9.90 mm. The two-step height belongs to the A 097 design: it seats more firmly in the bore and gives the lip more flexibility. A 097 means a single lip with a spring, which suits general retention of oil and grease.

You will find seals like this in gearboxes, pumps, electric motors, reducers and other power transmission equipment. They run on shafts at moderate speed and hold back lubricant loss while blocking dust and water. Agricultural machinery, construction equipment and production lines are common places to see them. The compact envelope helps in tight spots where larger seals will not go.

Before fitting, confirm the shaft and bore are clean and free of burrs or scratches. Coat the lip with the same oil or grease the equipment uses. Drive the seal in squarely with a tube that bears on the outer ring, and do not hit the lip. Keep shaft runout within the limits set for radial shaft seals. If the shaft is worn, a repair sleeve or a different size may be the better route.
