The DBH 9277 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 21 mm shaft, a 32 mm housing bore and has a 7.50 mm height, with the Mx-R-H design indicating a sealing lip, metal case and spring. MR supplies this seal as part of its sealing line for gearboxes, pumps, motors and transmission assemblies.

The code 9277 is the manufacturer's identifier within the DBH oil seal range. The Mx-R-H designation describes the construction: an elastomeric lip, a metal outer body and a spring that maintains lip contact on the shaft. This combination is intended for rotating shafts where oil or grease must be retained and external particles, water or dust kept away from the bearing or gear area.

These dimensions suit small-diameter shafts and tight mounting spaces. You will find seals like this in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the seal protects the lubricant and the internal components, reducing the need for frequent maintenance when the shaft and housing are in good condition.

When selecting a replacement, confirm the three mounting dimensions: shaft 21 mm, housing 32 mm and width 7.50 mm. The shaft surface should be ground, free of burrs and hard enough to support the lip. During installation, coat the lip with the same oil used in the equipment, press the seal in squarely to the shaft and avoid hitting it. If the shaft shows wear, an auxiliary lip version may be worth considering.
