The DBH 5478 is a radial shaft seal that fits into a housing and runs against a rotating shaft to keep lubricant in and contaminants out. With a 101.60 mm shaft diameter, a 126.95 mm housing bore and a 12.70 mm width, it matches a standard size found in many types of industrial equipment. MR supplies this brand and can help you confirm the right seal for your application.
This oil seal carries the DBH brand and the designation 5478. Its three key dimensions are shaft 101.60 mm, housing 126.95 mm and width 12.70 mm. The Lx design refers to a seal with a sealing lip and an outer metal case, made for press-fit installation in a cylindrical housing. The flexible lip rides on the shaft and stays in contact even when there is slight misalignment or vibration, which is common in rotating equipment.
Seals like this are found in gearboxes, pumps, electric motors, rollers and transmission units where a shaft turns inside a lubricated housing. They also appear in environments with dust or water, where the seal keeps oil or grease free of contamination. Because the shaft size is close to 4 inches, it shows up often in imported machinery and in continuous-process lines.
When choosing a seal, confirm that the shaft diameter, housing bore and width match the values shown. Inspect the shaft surface as well: wear or a groove in the contact area will stop the lip from sealing correctly. At installation, coat the lip with the same oil or grease used in the equipment, press the seal in squarely to the shaft and avoid hitting it. Remove any burrs from the housing before fitting.
To get a quote, send the complete part number or the three dimensions. With that information we can search for an alternative in the same Lx design or a similar one. We can also check whether the original seal has a special feature, such as an auxiliary lip or a spring, so the replacement does the same job.
Send the DBH 5478 part number by WhatsApp to request a quote. If you are unsure about the size or design, include a photo of the old seal or the dimensions you measured with a caliper. That helps us confirm the replacement is correct and prevents downtime from a seal that does not fit.

- How do I know if this oil seal replaces the one I have installed?
- Measure the shaft diameter, the housing bore and the width of the old seal with a caliper. If they match 101.60 x 126.95 x 12.70 mm and the design is similar, it is compatible. If in doubt, check with us and send a photo.
- What does the Lx design mean on this oil seal?
- The Lx design indicates a construction configuration of the seal, with a sealing lip and metal case for press-fit mounting. It is a manufacturer designation that helps identify the seal geometry, not a performance standard.
