The DBH 8340Pol is a radial shaft seal built for a 50 mm shaft, a 65 mm housing bore and a 10 mm height. Its Lz-R configuration pairs a primary sealing lip with a secondary dust lip, so lubricant stays in and grit stays out on rotating-shaft equipment such as gearboxes, pumps and motors. MR Industrial Accessories supplies this brand and can help you match the seal to your application.

Reading the reference is straightforward: 8340Pol identifies the seal, and the three figures that follow it in the size callout are shaft 50 mm, housing 65 mm and height 10 mm. The Lz-R version carries a main lip plus an outer dust lip on a metal case that presses into the bore. Seals built this way are common on rotating shafts where airborne particles are part of the operating environment.

Typical service includes gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment. The job is always the same: hold the oil or grease inside and keep dust, water and chips away from bearings and gears. Because that duty protects the internal components, the seal plays a direct role in how often corrective maintenance comes around.

Installation calls for a few checks. Confirm the shaft size falls within the recommended tolerance and that the running surface is free of scratches or wear. The bore needs a suitable finish and enough depth for the full height of the seal to seat. Lubricate the lip with the same lubricant the equipment uses, drive the seal in with a tool that will not catch the lip, and if the shaft shows a worn track, a wear sleeve is worth considering.
