The DBH 1212 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It presses into the housing and its flexible lip rides on the shaft, maintaining dynamic contact. A leaking seal can shorten bearing and gear life, so this part matters in gearboxes, pumps, motors and transmission drives.

This seal fits a 57.15 mm shaft, an 82.58 mm housing bore and a height of 12.70/14.95 mm. The A 396 design has a sealing lip and metal body for rotating shaft applications. Its millimeter dimensions make it easy to match during a replacement or a new build. As a radial seal, it is intended for continuous lubrication and moderate temperatures.

You will find it in gearboxes, centrifugal pumps, electric motors, compressors, mixers and power transmission equipment. In each case it stops oil or grease loss and keeps dust, water and particles away from bearings. It also appears in agricultural machinery, process equipment and hydraulic systems where a shaft turns inside a fixed housing. Selection comes down to shaft diameter, housing bore and operating conditions.

Before installing, check the shaft for burrs or wear and make sure the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the machine, then press the seal in evenly. The 12.70/14.95 mm height tells you the cavity depth it can seat in. Do not let the lip roll over during installation. If the shaft has splines or grooves, a wear sleeve may be needed to protect the sealing surface.
