When a rotating shaft needs its lubricant kept in and outside matter kept out, a radial lip seal such as the DBH 1277 does that job. It fits a 150 mm shaft in a 180 mm bore, with a 14.5/16 mm height, and carries the A 423 design, a single lip with a spring. This seal is a common choice for gearboxes, pumps, motors and other industrial equipment. MR supplies the DBH line and can help you match the seal to your equipment.
Reading the reference is straightforward. The DBH brand and the 1277 designation identify the item, while the three figures that follow describe the fit: shaft diameter (d) 150 mm, housing diameter (D) 180 mm and height (h) 14.5/16 mm. The A 423 designation tells you the seal has one lip with a spring, a configuration intended for retaining oils and greases. Keep the 1277 code on hand, since it is the fastest way to locate the part in a catalog or an ordering system.
Applications are those where a shaft turns and lubricant has to stay confined: gearboxes, centrifugal pumps, electric motors, speed reducers and process machinery that runs continuously. Sealing the shaft at that point also keeps dust, water and particles away from the bearings and gears, which supports longer maintenance intervals.
Correct installation starts with the mating surfaces. Check shaft hardness and roughness, and make sure the housing bore is clean and free of burrs. Apply lubricant to the lip before pressing the seal in, and confirm the spring is seated where it belongs. When selecting the seal, take peripheral speed, working temperature and the fluid being retained into account. If any of those details are unclear, share your equipment data and we can review it with you.

Frequently asked questions
- What are the dimensions of the DBH 1277 seal?
- Shaft diameter 150 mm, housing diameter 180 mm and height 14.5/16 mm. Those three figures define the fit, so equipment must have a shaft and bore of those sizes.
- Where is this seal used?
- On rotating shafts of gearboxes, pumps, electric motors and general industrial machinery. It retains lubricant and blocks contaminants, which protects bearings and gears. It suits oils and greases under moderate speed and temperature conditions.
- How do I request a quote or an equivalent?
- Send the code 1277 or your shaft and housing dimensions by WhatsApp. We quote the DBH seal or look for an equivalent alternative, and we can advise you if a special design is needed.
