The DBH 1127 is a radial shaft seal that presses into a housing to keep lubricant in and contaminants out. Its A 369 design combines a sealing lip with a metal outer body that seats in the cavity. You will find it on rotating shafts in gearboxes, pumps, motors, and transmission equipment. MR Industrial Accessories supplies this brand and helps you match the size to your application.

The seal fits a shaft of 37 mm, a housing bore of 66 mm, and a height of 9.50/13.50 mm. The code 1127 is the manufacturer's part number, while A 369 describes the lip and outer body geometry. The height range means the seal can sit in cavities of different depths within that span, as long as the lip contacts the shaft properly. It is a standard replacement item for oil- or grease-lubricated rotating shafts.

Common uses include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each case, the seal stops lubricant from escaping and keeps dust, water, and particles away from bearings and gears. Agricultural machinery, earthmoving equipment, and process lines with continuous or intermittent shaft rotation also rely on this type of seal.

When selecting a replacement, verify that the shaft diameter, housing bore, and height match the original. The shaft surface should be ground and free of grooves or burrs; the housing must be clean and undistorted. During installation, lubricate the lip with the same oil or grease used in the machine and press the seal in squarely to avoid damage. If the shaft is worn, an auxiliary lip version may be needed.

For an equivalent, send the part number 1127 along with the shaft and housing dimensions and the height. A photo of the old seal or the housing drawing also helps. With that information, MR Industrial Accessories provides a quote for the exact size or a compatible alternative from the same DBH line.
