The DBH 8701 is a radial shaft seal built to keep lubricant in and contamination out where a shaft turns. It measures 47.60 mm at the shaft, 70.55 mm at the housing and 13.50 mm in height, and it uses the Mz design. Gearboxes, pumps, electric motors and power transmission equipment are the usual places this seal shows up. MR Industrial Accessories supplies this brand and can help you confirm the right oil seal for the job.

Reading the code is straightforward: DBH is the seal family, 8701 is the item reference, and the three figures follow the standard order of shaft, housing and height. So the shaft seat is 47.60 mm, the housing bore is 70.55 mm and the overall width is 13.50 mm. The Mz design describes a sealing lip combined with a metal case, a configuration made for rotating shafts. Because these are standard housing dimensions, the seal drops into existing bores and lets you replace a worn unit without machining the machine.

Sealing matters most wherever rotation and lubrication meet. Gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives all rely on a lip seal to hold oil or grease in place while blocking dust, water and abrasive particles from reaching the bearings. A seal that fits and seats correctly protects the bearing set behind it, which is where most of the cost of a failure sits.

Selection comes down to matching the three dimensions of the original seal, and the Mz geometry has to be respected as well. At installation, coat the lip with the same oil or grease the application runs on, press the seal in squarely, and avoid hammering it. If the shaft surface is worn or scored, plan for a repair or look at a seal with an auxiliary lip before you install a new one.

If you need an equivalent, send code 8701 or the dimensions 47.60 x 70.55 x 13.50 mm, along with the equipment type and operating conditions. We can suggest compatible alternatives for your requirement.
