For rotating equipment that must keep lubricant in and contaminants out, the DBH 1284 oil seal provides a dependable radial shaft sealing solution. It is designed for shafts of 47 mm and housings of 80 mm, with a height profile of 7.50/26.00 mm and an Ms construction. As a wear component, it should be replaced at the first sign of leakage or contaminant ingress. MR Industrial Accessories LLC supplies this seal as part of its sealing product line.
This seal is specified for a 47 mm shaft and an 80 mm bore. The overall height is 7.50/26.00 mm, reflecting the two-part profile common in Ms designs. The Ms designation indicates a metal case with an elastomeric sealing lip. The code 1284 identifies this exact size within the DBH series, making it straightforward to reference when requesting a quote.
Typical installations include gearboxes, pumps, motors, rollers, and other power transmission equipment where oil or grease retention is critical. The seal also works well in environments with dust, moisture, or metal chips, where the lip must both hold lubricant and block foreign particles. Maintenance teams in industrial plants and mobile equipment operations rely on this type of seal for dependable performance.
Proper installation begins with a clean shaft free of burrs or scoring. The sealing lip should be lightly lubricated before fitting, and the seal pressed into the housing using a tool that contacts only the outer diameter. The seal must sit square to the shaft and at the correct depth. If the housing bore has any burrs, remove them first. Operating speed, temperature, and fluid type should guide the final selection.
If you need to confirm compatibility or find an equivalent, share the part number, shaft and housing dimensions, and a photo of the old seal. MR can then suggest a compatible option or advise if a different lip material or design would better suit your application.
