The DBH 8290 is a radial shaft seal that keeps oil or grease contained where a shaft passes through a housing. With a 50 mm shaft, 67 mm housing bore and 8 mm height, and an Lx design, it suits gearboxes, pumps, electric motors and power transmission equipment. MR Industrial Accessories supplies this brand and can help you verify the dimensions before you request a quote.

This seal carries the designation 8290 and the Lx design, which corresponds to a single lip with a spring. The lip retains lubricant and keeps dust out in rotating applications. You will find it on gearboxes, centrifugal pumps, electric motors, rollers, conveyors, machine tools and process equipment where oil leaks and contaminant entry need to be controlled. Because it fits a 50 mm shaft, it is common on medium-sized equipment with an established housing bore.

The three key dimensions are shaft 50 mm, housing 67 mm and height 8.00 mm. Before ordering, confirm these values against your equipment, since the housing bore and shaft diameter determine whether the seal seats correctly. If the shaft shows a marked groove, consider repositioning the lip or repairing the surface rather than installing a new seal over the wear track.

During installation, check that the shaft is free of burrs or wear and that the housing is clean and undented. Lubricate the lip, then press the seal in perpendicular to the shaft without distorting it. Proper alignment and lubrication help the seal perform as expected.
