The DBH 8691 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. It fits a 44 mm shaft, a 76.10 mm housing bore and a 12.70 mm height. The Lz design combines a spring-loaded lip with a dust lip, so it seals oil or grease while blocking dust and water. You will find this size in gearboxes, pumps and transmission equipment where bearing protection matters.

The code breaks down simply: shaft 44 mm, housing 76.10 mm, width 12.70 mm, and Lz for the lip arrangement. The main lip, backed by a spring, presses lightly against the shaft to hold lubricant during rotation. The secondary dust lip faces outward and stops particles from reaching the bearing. Both lips work together, which is why the Lz style suits dirty or damp environments.

This seal size appears in gearboxes, centrifugal pumps, mixers, conveyors, electric motors and agricultural or road machinery. In each case, the seal protects a bearing from moisture and grit. As the lip ages, it hardens or wears, lubricant escapes and the bearing is exposed to premature failure. Replacing the seal at the first sign of weeping is cheaper than replacing the bearing later.

Before ordering, confirm the shaft diameter, housing bore and depth match the old seal. The shaft surface should be ground and free of burrs, nicks or deep scratches, since any of these will damage the lip quickly. During installation, coat the lip with the same grease or oil used in the equipment, keep the seal perpendicular to the shaft and drive it in with a tube or spacer that contacts only the outer edge. If the housing has a chamfer, seat the seal fully.

To quote part number 8691, send the three dimensions of the old seal and the design type. We compare that data against the series we supply and suggest equivalent options when a direct match is not available. Material variants can also be reviewed based on the fluid and operating temperature. Bearings, housings and lubricants for the same repair can be included in one inquiry.
