The DBH 9642 is a radial shaft seal that keeps lubricant inside a housing and keeps dust, water and other contaminants out. Its code tells you the main sizes: shaft 65 mm, housing 85 mm, height 8.00/3.80 mm, in the Lz design. You will find seals like this one on gearboxes, pumps, electric motors and other transmission equipment, where they help bearings and gears last longer. MR Industrial Accessories supplies this brand and can help you match the right seal to your equipment.

This is a single-lip seal, and the numbers in its designation describe its geometry. The 65 mm figure is the shaft diameter (d), the 85 mm figure is the housing bore (D), and the 8.00/3.80 mm figure is the overall height, with 3.80 mm in the lip zone. The Lz design refers to the shape of the lip and the outer body, which is intended to hold oil in and keep dust and water out. It seats in a housing with a shoulder, so contact on the shaft stays even.

You will typically find this seal on gearboxes and speed reducers, centrifugal pumps, electric motors and power transmission equipment, as well as on fan, mixer and conveyor shafts. In all of these, its job is to stop lubricant from escaping and to block abrasive particles that would otherwise speed up wear on bearings and gears. A seal that fits and sits correctly helps keep equipment running between service intervals and keeps maintenance costs down.

Before ordering, check that your shaft and housing match the 65 mm and 85 mm figures, and that the 8.00/3.80 mm height fits the housing depth and the space you have. The Lz design needs a housing with a shoulder so the seal seats firmly. When you install it, coat the lip with the same oil used in the equipment, keep the seal away from impacts, and check that the shaft has no burrs or splines that could cut the lip. Careful installation is what gets the most service life out of the seal.
