Part number 8670 belongs to the DBH line of radial shaft seals. In this size the seal runs on a 57.30 mm shaft, sits in an 84.00 mm housing bore and measures 8.00 mm in height, with the Mz lip configuration. MR Industrial Accessories supplies this brand and can review your application data before you commit to a part.

Reading the designation is the quickest way to confirm a match: the three figures give shaft, bore and height in that order, so 57.30 mm, 84.00 mm and 8.00 mm. The Mz designation describes how the lip and body of the seal are built, which suits ordinary oil and grease retention duties. Equipment that was originally fitted with this size can take the 8670 as a like-for-like replacement.

These seals sit where a rotating shaft passes through a housing and the lubricant on one side has to stay there. Gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools all rely on that barrier, and it also keeps dust, water and particles away from the bearing cavity. A seal that fits correctly protects the bearings and keeps the assembly running as intended.

Fitting matters as much as the size. Inspect the shaft for burrs, nicks or wear marks that could cut the lip, coat the lip with the same oil or grease the equipment uses, and press the seal in with a tool that loads the outer ring evenly. When selecting a replacement, consider how fast the shaft turns, the temperature at the seal and whether the elastomer can handle the fluid being sealed. The Mz design covers standard operating conditions.
