The DBH 5088 is a radial shaft seal designed to keep oil or grease in and dust out where a shaft turns inside a housing. It presses into the housing, and its flexible lip rides on the shaft. Because it is a wear part, it gets replaced when lubricant starts escaping or contaminants get in. MR Industrial Accessories supplies this brand and can help you match the size to your equipment.

This seal is identified as DBH 5088. Its designation tells you the three key dimensions: shaft 17 mm, housing 34 mm, height 4.00 mm. The Lx design is a single-lip seal with a spring, made for rotating shafts that run with lubrication. The 5088 number is simply the size code, not a serial number. If your machine calls for a 17 x 34 x 4 mm seal, this is the code to look for.

You will find this type of seal in gearboxes, electric motors, pumps, compressors, machine tools, and transmission equipment. In general, it fits any assembly where a shaft rotates inside a housing and oil or grease must be retained while dust or water is kept out. It also works in low-speed applications and where axial space is tight, as with this 4 mm height.

During installation, make sure the shaft is clean, free of burrs and marks, and that the surface under the lip has a fine finish. Lubricate the lip before inserting the seal, and press it in perpendicular to the shaft using a tube or spacer that contacts the outer ring, never the lip. If the housing has a chamfer, follow its angle to avoid damaging the seal. Selection depends on speed, temperature, and the lubricant type; if you do not have that data, ask us.

If you need an equivalent, send us the complete seal code, the shaft, housing, and height dimensions, and a photo of the old part if possible. We will review alternatives within the DBH line or from other brands we carry. We can also tell you the standard size that replaces the one you are using, while keeping the original housing dimensions.
