The DBH 5494 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns. Its size — 56 mm shaft, 76.40 mm housing, 12.70 mm height — suits medium-sized assemblies with tight axial room. Pressed into the housing, it runs against the shaft with a dynamic lip. As a wear part, it calls for replacement when leaks or dirt ingress show up.

This seal carries the DBH brand and the code 5494. The dimensions are shaft 56 mm, housing 76.40 mm, width 12.70 mm. The Lz design denotes a single lip with spring for rotating shafts that see lubrication. Reading the code makes it easy to find in the catalog and compare with other seals in the same family. It is a standard item among the seals and radial shaft seals that MR Industrial Accessories supplies.

Seals this size often appear in centrifugal pumps, electric motors, gear reducers, gearboxes, and power transmission equipment. In each case they do two jobs: hold oil or grease inside the assembly and block dust, water, or particles from reaching the bearing or shaft. Machine tools, agitators, and process equipment with continuous shaft rotation also rely on them, since sealing affects bearing life.

Selecting the right seal starts with caliper measurements of the shaft and housing, plus a check of the available height. The shaft surface should be ground and free of burrs; too much roughness speeds up lip wear. During installation, coat the lip with the same oil used in the equipment and use a support tube to avoid damage. If the shaft has a groove or wear, a repair sleeve may be needed before fitting the new seal.

For an equivalent, send the code 5494 along with the dimensions you measured. The number stamped on the old seal or the equipment maker's designation also helps. With that information, MR Industrial Accessories compares it against the options and identifies the size that fits without modifying the housing. If space permits, a different height or a design with an extra lip can be considered.
