The DBH 8977Pol is a radial shaft seal built for rotating shafts. It keeps lubricant where it belongs, inside the housing, and blocks dust, particles and moisture from getting in. Its three key measurements are a shaft diameter of 85 mm, a housing bore of 110 mm and a height of 12.00 mm, and it uses the Lx design. Within the DBH line, 8977Pol is the code that identifies this particular seal. MR Industrial Accessories supplies this brand and can help you confirm it is the right match for your equipment.

Reading the code and the dimensions together is the fastest way to check a replacement. The 85 mm figure refers to the shaft the seal rides on, the 110 mm figure to the bore it presses into, and the 12.00 mm figure to its overall height. The Lx designation tells you this is a single-lip seal with a spring, which is what you want on a shaft that turns continuously. Before installing anything, measure both the shaft and the housing. A small mismatch is enough to cause leaking or early failure.

You will run into this seal in gearboxes, pumps, electric motors, rollers and other power transmission equipment. Its job is to protect bearings and gears in oil or grease environments, holding the lubricant in while keeping dust and water out. Industrial machinery, process equipment and conveying systems that run for long stretches are typical homes for it.

Three things drive the selection: how fast the shaft spins, the temperature the seal will see, and the lubricant in use. The Lx design with its spring suits continuous rotation. When mounting, coat the lip with the same oil or grease the equipment uses, seat the seal square to the shaft, and press it in without hammering on the lip. If the shaft surface is worn, a seal with an extra lip is worth considering.

If you are replacing an original, send the 8977Pol code or the measurements you took. We check the designation against the catalog and can offer alternatives from the same brand or another that does the same job, along with guidance on housing and shaft compatibility. The goal is a seal that fits the first time and holds up in service.
