The DBH 6771 is a radial shaft seal built to keep lubricant in and contaminants out where a shaft turns inside a housing. Its size — shaft 49.20 mm, housing 68.22 mm, height 9.52 mm — fits common gearbox, pump and electric motor arrangements. MR supplies this brand and can help you confirm the right seal for the job.

Part number 6771 belongs to the DBH line of radial shaft seals. The Lx design uses a sealing lip with a spring, which holds oil or grease against a rotating shaft. The lip contacts the shaft while the outer case presses into the housing bore, so the joint stays tight in service.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In each case it keeps dust and water away from bearings and gears and stops lubricant from escaping. Because a failed seal leads to contamination and wear on internal parts, it is a routine item in industrial maintenance.

Before fitting, check the shaft for burrs or wear and make sure the sealing surface is clean. Coat the lip with the same oil or grease used in the application, then press it in squarely. The housing bore should be free of debris and distortion. When choosing a seal, match it to shaft speed, operating temperature and how the elastomer reacts to the fluid being retained.
