The DBH 8304 radial shaft seal keeps lubricant in and contaminants out of rotating machinery. It measures 45 mm at the shaft, 84.8 mm at the housing, and 21 mm in height, with design A 214. MR Industrial Accessories supplies this seal and can help you match it to your equipment.

This seal carries the designation 8304 and is built to the A 214 design. That design uses a single lip with a spring, which rides on the shaft to hold oil or grease in place. The outer case presses into the housing to complete the seal. You will find it in gearboxes, pumps, electric motors, and transmission assemblies.

In those applications, the seal shields bearings and gears from dust, water, and particles while preventing lubricant from leaking out. Because a failed seal can lead to unexpected downtime and costly repairs, it is a part that maintenance teams watch closely.

Proper installation matters. Inspect the shaft for burrs or wear, and make sure the housing is clean and undistorted. Before fitting the seal, coat the lip with the same oil or grease used in the equipment. When selecting a replacement, consider shaft speed, operating temperature, and the fluid being sealed. If the shaft shows a worn track, a repair sleeve or a different size may be needed.
