The DBH 5478 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 101.60 mm shaft, 126.95 mm housing and 12.70 mm height correspond to a standard size widely used in industrial equipment. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for the application.

This item is a DBH brand oil seal, identified by the designation 5478. Its dimensions are 101.60 mm shaft diameter, 126.95 mm housing diameter and 12.70 mm height. The Lx design corresponds to a configuration with a sealing lip and outer metal case, intended for press-fit mounting in a cylindrical housing. The flexible lip runs on the shaft and maintains contact even with slight misalignment or vibration typical of rotation.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing with lubricant. They also appear in applications exposed to dust or water, where the seal prevents contamination of the oil or grease. As a shaft size close to 4 inches, it is common in imported equipment and in continuous-process machines.

To select the seal, verify that the shaft diameter, housing diameter and height match the values on the product page. Check the condition of the shaft surface: wear or a deep groove in the contact area prevents the lip from sealing properly. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it. If the housing has burrs, clean it before fitting the seal.

If you need a nearby size or an equivalent from another brand, send us the full part number or the shaft, housing and height dimensions. With that data we can look for an alternative with the same Lx design or similar. We can also advise you if the original seal has a special configuration, such as an auxiliary lip or spring, so the replacement performs the same function.
