The DBH 8198 is a radial shaft seal with an Ls design, sized for a 28.46 mm shaft, a 36.50 mm housing bore and a 5.50 mm height. It keeps lubricant in and contaminants out on rotating shafts, and it is a wear part that should be replaced when it leaks or the elastomer hardens.

The code 8198 is the reference to order this seal. Its three dimensions tell you where it fits: shaft 28.46 mm, housing bore 36.50 mm, height 5.50 mm. The lip runs against the shaft while the outer diameter presses into the housing to seal. The compact 5.50 mm height suits assemblies with limited axial space, such as medium-section bearings and split plummer block housings.

You will find this seal in gearboxes, pumps, electric motors, transmission shafts and other power transmission equipment, as well as in agricultural machinery, process equipment and lubrication systems. Choosing the right part depends on shaft speed, operating temperature and the lubricant used, so check those conditions against the seal before ordering.

Before installation, clean the shaft and housing and remove burrs or scratches. Lubricate the lip, press the seal in evenly and do not strike it. Shaft eccentricity and axial play must stay within the limits recommended by the manufacturer. If the old seal failed, inspect the shaft surface: wear there will shorten the life of the new seal. Proper alignment helps the seal last.

To request a quote, send the code 8198 or the three dimensions. A photo of the old part or the assembly drawing also works. MR Industrial Accessories supplies seals and can suggest equivalents and help you choose. Quotes are handled by WhatsApp or email, and the team replies promptly.
