The DBH 1018 is a radial shaft seal built for a 22.22 mm shaft and a 34.92 mm housing bore, with a 7.92 mm height. Its Mz configuration pairs a primary sealing lip with a secondary dust lip, so the contact zone stays protected from dirt. You will find it in gearboxes, pumps, motors and other power transmission equipment, where it keeps oil or grease in and contaminants out.

This seal carries the DBH designation and the code 1018. Its three key dimensions are a shaft diameter of 22.22 mm, a housing bore of 34.92 mm and a height of 7.92 mm. The Mz design means there is a main lip doing the sealing plus an auxiliary lip for exclusion, which suits moderate dust or dirt exposure. The elastomer lip rides against the rotating shaft, and the metal outer case holds the seal firmly in the housing.

You will typically see this seal in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and general power transmission equipment. It also shows up in machine tools, conveyors and hydraulic systems, wherever lubricant has to stay contained and bearings need protection from particles. Because the size is compact, it fits equipment with small shafts and limited mounting space.

When selecting the seal, confirm that the shaft diameter, housing bore and height all match the values above. The shaft surface should be ground and hard enough to keep lip wear under control. At assembly, coat the lip with the same oil or grease used in service, press the seal in square to the shaft, and never hit the lip directly. Any burrs or roughness in the housing should be removed first.

If you are looking for an equivalent, just send the code 1018 or the shaft and housing dimensions. MR Industrial Accessories can offer alternatives from other series and brands to match your application, and we can help you pick the lip design that fits the contaminant and rotation speed.
