The DBH 9638 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 47.70 mm shaft in a 73.10 mm housing, with a stepped height of 9.50/17.50 mm and the A 270 profile. MR Industrial Accessories supplies this brand and helps you confirm the right seal for the job.

The part number 9638 identifies a DBH oil seal. Its dimensions are shaft 47.70 mm, housing 73.10 mm, and height 9.50/17.50 mm. The A 270 designation refers to a lip seal configuration that may include a secondary lip or dust lip; exact details are checked against the manufacturer's data. The stepped height points to a housing with a shoulder or a thicker section, which can add stability in the bore.

You will find this seal on rotating shafts in gearboxes, centrifugal pumps, electric motors, conveyor rollers, and power transmission equipment. Its job is to protect bearings and gears from dust, water, and particles while holding oil or grease in place. It is common in agricultural machinery, mining equipment, process plants, and hydraulic systems where sealing must hold up.

When selecting a replacement, match the shaft and housing dimensions to the component being sealed. The stepped height must seat without interference. Inspect the shaft surface for wear, scratches, or burrs that could damage the lip. Lubricate the lip with the same oil or grease used in the application and install with a suitable tool to avoid deforming it. If the shaft has a groove or shoulder, ask our team before ordering.
