The DBH 8742 is a radial shaft seal designed to retain lubricant and block contaminants in rotating equipment. It fits a 50 mm shaft and a 68 mm housing bore, with a height of 7.00/9.00 mm. The A 171 design features a sealing lip and an outer case that presses into the housing. MR Industrial Accessories supplies this seal as part of its line of seals and oil seals for maintenance professionals across the United States and Latin America.

Common applications include gearboxes, electric motors, centrifugal pumps, rollers and transmission shafts. In these machines, the seal performs two functions: it keeps oil or grease from escaping and protects bearings from dust, wash water or chips. A seal in good condition helps extend bearing life and reduces unplanned downtime.

When replacing a radial shaft seal, inspect the shaft for burrs or wear and make sure the housing is clean and free of deformation. Lubricate the lip with the same lubricant used in the equipment, then press the seal in with a suitable tool, applying even force on the outer case. Do not strike the sealing lip. If the shaft shows a deep groove, consider a design with an auxiliary lip.
