The DBH 1167 is a radial shaft seal built to sit in a 52.00 mm housing bore with a 10.00 mm height. Its job on a rotating shaft is twofold: hold lubricant where it belongs and keep dust, water and other contaminants out of the assembly. You will find this type of lip seal on gearboxes, pumps, electric motors and other transmission equipment. It forms part of the seals and oil seals line that MR Industrial Accessories LLC supplies to maintenance and purchasing teams.

This seal follows the A 378 design. A metal case gives the unit its rigidity, while an elastomeric lip does the actual sealing against the shaft, which is what allows it to work under continuous rotation. When you read a seal designation like this one, the two figures that matter most are the housing bore and the height, since those decide whether the part will seat correctly in your equipment.

Typical installations include gear reducers, centrifugal pumps, electric motors, conveyor rollers and power transmission components. The same seal also turns up in machine tools, compressors and hydraulic systems where oil or grease has to stay contained and the bearings need protection from the surrounding environment. Treat it as a wear part: once lubricant starts escaping or contamination gets in, replacement is the practical move.

Sizing comes down to three checks before you order: shaft diameter, housing bore and the height available in the housing. The shaft surface should be ground and free of burrs, and the housing clean with a chamfer that will not cut the lip as it goes in. Lubricate the lip before insertion and drive the seal in with a support tube that presses only on the outer ring. If the shaft itself shows wear, an oil seal with an auxiliary lip is worth considering.

If you are after an equivalent to the DBH 1167, send the part number along with your shaft, housing bore and height measurements, plus a photo of the part. That is usually enough for our team to search for alternatives in the same radial shaft seal category. We can also tell you whether the A 378 design fits your application or whether a different lip profile or material would serve you better.
