The DBH 1127 radial shaft seal is a lip seal that mounts in a machine housing to retain lubricant and block the entry of dust, water or particles. Its A 369 design combines a sealing lip with a metal body that press-fits into the cavity. It is used in gearboxes, pumps, electric motors and transmission equipment operating with rotating shafts. MR Accesorios Industriales supplies this official brand and advises you on choosing the right size.

This seal has a shaft diameter of 37 mm, a housing diameter of 66 mm and a height of 9.50/13.50 mm. The designation 1127 corresponds to the manufacturer's part number and the A 369 design defines the geometry of the lip and the outer body. The height range indicates that the seal can be seated in cavities with different depths within that interval, provided the lip bears correctly on the shaft. It is a standard replacement component for rotating shafts with oil or grease lubrication.

Typical applications include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. In all cases, the seal prevents lubricant leaks and protects bearings and gears from the entry of external contaminants. It is also used in agricultural machinery, earthmoving equipment and process lines where the shaft rotates continuously or intermittently.

To select the seal, check that the shaft diameter, housing diameter and height match the values of the original part. The shaft surface must be ground and free of grooves or burrs; the housing, clean and free of deformation. During installation, lubricate the lip with the same oil or grease used in the equipment and press perpendicularly so as not to damage it. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.

If you need an equivalent or a close size, send us the part number 1127 together with the shaft and housing dimensions and the height. You can also send a photo of the old part or the housing drawing. With that data, at MR Accesorios Industriales we send you a quote for the exact size or for a compatible alternative within the same DBH line.
