The DBH 6770 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. Its Mx design uses a spring-loaded single lip. The seal measures 31.75 mm at the shaft, 50.80 mm at the housing, and 10.70 mm in height, making it a direct replacement for industrial equipment where a failed seal can lead to bearing damage and unplanned downtime.

The DBH 6770 carries the code 6770 and fits shafts of 31.75 mm (d), housings of 50.80 mm (D), and has a height of 10.70 mm (h). The Mx design is a single-lip, spring-energized configuration for rotating shafts with lubrication. Its elastomer lip and metal case maintain dynamic contact and tolerate minor misalignment.

You will find this seal in gearboxes, pumps, electric motors, conveyor rollers, and power transmission equipment. It also serves in agricultural machinery, mixers, and industrial washing systems where water or dust is present. In these applications, the seal protects bearings and stops oil or grease leaks, which extends assembly life and reduces maintenance.

When selecting the DBH 6770, confirm that the shaft and housing dimensions match the values above. The shaft should be clean, free of burrs and deep marks, and the housing bore should have a proper chamfer to avoid damaging the lip during installation. Lubricate the lip before pressing it in and use a support tube that contacts only the outer ring. For high-speed or heavily contaminated conditions, ask about double-lip or alternative material variants.

If you need an equivalent seal, send us code 6770 or the dimensions of your sample. A photo of the old seal along with shaft and housing dimensions also helps. We cross-check that data against the available series and suggest compatible alternatives.

MR Industrial Accessories supplies the DBH brand as part of its seals and oil seals line. If you have questions about the application or want to confirm the size, message us on WhatsApp with code 6770 and we will provide the technical information you need.
