The DBH 9214 is a radial shaft seal designed to keep lubricant in and contaminants out of rotating equipment. Its profile measures 40.00 mm at the shaft, 52.00 mm at the housing and 3.00/8.50 mm in height, with an A 082 design that combines a single lip and a spring. This configuration suits gearboxes, pumps and motors where space at the seal seat is limited.

The A 082 designation points to a single lip with a spring, intended for rotating shafts at moderate speeds. The lip elastomer and metal case form one unit that presses into the housing and seals against the shaft. The stepped height — 3.00 mm at the lip, 8.50 mm at the body — allows installation in shallow bores without giving up sealing contact.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment where oil or grease must be retained and dust or water kept out. The seal also appears in machine tools, conveyors and agro-industrial machinery. Because it is a wear part, a hardened or scored lip will start to leak; replacing it early helps avoid damage to the shaft or bearing.

Before installation, confirm the shaft is clean and free of burrs or grooves, then lubricate the lip with the same oil or grease used in the equipment. The housing bore should be straight and undamaged. If the shaft shows wear, a seal with an auxiliary lip may be a better choice. Working speed and temperature also affect lip material selection, so consult us if your operating conditions fall outside the usual ranges.

If part number 9214 is not what you need, provide the shaft diameter, housing diameter and height, and we will search for an equivalent in DBH or another brand. Additional details — a photo of the old seal, the equipment type, the working conditions — help us identify the right option faster.
