The DBH 5134 is a radial shaft seal sized 17 mm shaft, 30 mm housing, and 7.00 mm height. It keeps lubricant in and contaminants out of small to medium equipment where axial space is tight. The Lz design means a single lip with a spring, suited to rotating shafts under permanent lubrication.

This seal combines a metal outer case that presses into the housing with an elastomer lip that rides on a ground shaft surface. The 17 mm shaft diameter, 30 mm housing diameter, and 7.00 mm height match common small pumps, low-power motors, gearboxes, compressors, mixers, and drive units. It is a dynamic seal for rotating shafts, not a static gasket or cover seal.

In service, the DBH 5134 retains oil or grease inside the assembly and blocks dust, water, and particles that would otherwise shorten bearing and gear life. You will find this size in machine tools, washing equipment, and irrigation systems as well. When the lip wears, leakage appears at the shaft, often within hours if the seal is not seated squarely.

For installation, inspect the shaft for burrs or deep marks in the contact zone and confirm the housing is clean and undistorted. Apply the same oil or grease used in the equipment to the lip, then push the seal in with a support tube that contacts only the outer case. Never drive on the lip. If the shaft shows wear, a repair sleeve may be needed.

To request a quote or an equivalent, send the part number 5134 along with the shaft, housing, and height dimensions. A drawing or photo of the old part helps us confirm design, lip material, or height variants if space permits. MR Industrial Accessories supplies the DBH brand as part of its seals line and serves customers across the United States and in several Latin American countries.
