The DBH 6721 oil seal is a radial shaft seal in Lz design, with a 75 mm shaft diameter, a 113 mm housing diameter and a 15.00 mm height. It keeps lubricant in and contaminants out on rotating shafts, and it is found in pumps, electric motors, reducers and gearboxes. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

The 6721 designation identifies the size and construction within the DBH line. In the Lz design, the seal has a flexible lip with a spring that rides on the shaft and holds sealing contact during continuous rotation. The dimensions to check are shaft 75 mm, housing 113 mm and height 15.00 mm. The seal is press-fit into the housing, and its lip runs against the shaft to retain oil or grease.

Typical uses include centrifugal pumps, electric motors, gearboxes, conveyor rollers and power transmission equipment. In each case the seal does two jobs: it stops lubricant from escaping and blocks dust, water or particles that would accelerate wear on bearings and gears. The same applies to agricultural machinery, road equipment and general industrial assemblies where reliable sealing protects the whole unit.

Before mounting, confirm the shaft measures 75 mm and the housing 113 mm, with tolerances and surface finish suited to radial seals. The 15.00 mm height has to match the housing depth. Lubricate the lip, use a mounting tool that will not damage the seal, and check that the spring sits correctly. If the shaft shows wear or grooves, a repair sleeve or a seal with an auxiliary lip is worth considering.
