The DBH 8451 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 42 mm shaft, a 58 mm housing bore and has a 13.50 mm overall width, and it uses the A 069 lip configuration. MR Industrial Accessories supplies this seal and can help you confirm the correct replacement for your application.
This seal is press-fit into a housing, and its flexible lip runs against the rotating shaft to form a barrier that holds oil or grease in place while blocking dust, water and particles. By keeping the lubricant clean, it helps protect bearings and gears from premature wear. You will find it in gearboxes, centrifugal pumps, electric motors, compressors, reducers and other power transmission equipment, as well as in agricultural machinery, conveyors and hydraulic systems where dependable sealing on a rotating shaft is required.
The compact, single-lip layout suits installations with limited space and moderate shaft speeds, as long as shaft and housing tolerances are within specification. Before installation, check that the shaft surface is free of burrs, scratches or other damage that could harm the lip, and confirm that the housing bore is clean and undistorted. Lubricate the seal before pressing it in, and use a driver that applies even pressure around the outer diameter to avoid cocking the seal.
When replacing an existing seal, compare the shaft, housing and width dimensions along with the lip style. If you are unsure, send us the original part number or the dimensions and we will help identify a suitable match. We can also advise on lip material and spring type based on the fluid being sealed and the operating temperature.
