The DBH 5471 is a radial shaft seal built to run on rotating shafts, keeping oil or grease where it belongs and holding dust, water and other contaminants out of the bearing cavity. It measures 88.90 mm at the shaft, 120.62 mm at the housing and 14.28 mm in height, and it uses the Lz design. That combination suits equipment where the axial space is tight but a dependable barrier is still needed. MR supplies this brand to industrial buyers throughout the United States and Latin America.

Part number 5471 comes from the DBH line of oil seals. Reading the size is straightforward: d is the shaft diameter at 88.90 mm, D is the housing bore at 120.62 mm, and h is the 14.28 mm height. The Lz design refers to a sealing lip with a profile that seats cleanly in a machined housing. The elastomer compound is chosen to stand up to the oils and greases normally found in industrial service.

You will run into this seal on gearboxes, pumps, electric motors, conveyor rollers and other power transmission assemblies. In each case its job is the same: hold lubricant in and keep particles and moisture out, so the bearings and bushings behind it are not exposed to premature wear. Agricultural machinery, mining equipment and production lines are common places to find it.

Selection starts with the bore and shaft. Confirm the shaft and housing measurements match the equipment before ordering, and check the shaft for scoring or wear, since a rough or grooved surface will damage the lip. Shaft tolerance and surface finish matter as much as the size. When installing, coat the lip with the same oil used in the system and press the seal in with a proper installation tube, keeping it square. Remove any burrs from the housing first so they do not cut the lip on the way in.

If you are cross-referencing, send part number 5471 or the exact dimensions from your equipment and we can look for an equivalent within our seal line while respecting the original specifications. Our broader range covers bearings, mounted units and housings, chains, sprockets, sheaves, belts, couplings, lubrication and maintenance tools. We also manufacture split plummer block housings, roller chains and sheaves.
