The DBH 8191 is a radial shaft seal built for rotating shafts. It keeps lubricant where it belongs inside the housing while blocking dust, water and other contaminants from getting in. The dimensions are shaft 44.00 mm, housing 65.00 mm and height 8.00 mm, and the Lz-R design identifies a lip seal with a spring. You will find this seal in gearboxes, pumps, electric motors and similar industrial equipment, and MR supplies it for your maintenance work.

Reading the code is straightforward. DBH is the brand, 8191 is the part number, and the three figures follow the usual order for this type of seal: shaft diameter first, housing diameter second, height third. That is 44.00 mm by 65.00 mm by 8.00 mm. The Lz-R designation tells you the seal has a sealing lip with a spring, which is what you want where oils and greases need to be held back. Keeping the part number 8191 on hand makes it easy to find the item in catalogs and ordering systems.

Where does this seal typically go? Gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment are the common spots. In each case the job is the same: shield the bearings and internal parts from outside contamination and stop lubricant from escaping. Treat it as a wear part and plan to swap it out during scheduled shutdowns rather than waiting for a leak to show up.

Installation matters as much as the part itself. Before fitting a seal like the DBH 8191, confirm the shaft and housing are clean and free of burrs or scratches. Coat the lip with the same oil or grease used in the application. Press it in evenly on the outer face and never push on the lip. If the shaft surface is worn, an auxiliary lip design may be worth considering. Final selection comes down to speed, temperature and the fluid involved.
