The DBH 5243 is a radial shaft seal from the DBH line, sized for a 20 mm shaft, 33 mm housing bore, and 10 mm height. Its Lx design features a single sealing lip with a spring, making it suitable for rotating shafts that require lubricant retention and protection against dust, water, or particles. This seal helps extend the life of bearings and bushings in pumps, electric motors, gearboxes, and transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the correct size.

The 5243 code identifies a specific size within the DBH seal range. The dimensions are: shaft 20 mm, housing 33 mm, width 10 mm. The Lx profile indicates a single lip with spring, intended for rotating applications with lubrication. This code should not be confused with inch-based seals or other profiles. It is a precision component that contacts both the shaft and the housing bore.

Typical uses for a 20x33x10 mm seal include centrifugal pumps, low-power electric motors, gear reducers, mixers, fans, and belt or chain drives. It also appears in machine tools, washing equipment, and hydraulic systems where oil or grease must be contained. In each case, the seal protects bearings and helps extend assembly life when installed on a sound shaft surface with proper lubrication.

For proper installation, inspect the shaft for burrs or wear and ensure the housing is clean and undistorted. Lubricate the lip with the same oil or grease used in the equipment before pressing it in. The 10 mm height fits standard cavities. If the shaft has a groove or significant wear, consider a seal with an auxiliary lip or a different size. Selection depends on speed, temperature, and the fluid being retained.
