The DBH 8312 is a radial shaft seal built to the A 109 design. It sits between a rotating shaft and its housing to keep lubricant in and contaminants out. The seal fits a 55 mm shaft and a 70 mm housing, with a height of 6.00/9.50 mm. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

This seal carries the designation 8312 and the code DBH 8312. Its key dimensions are shaft (d) 55 mm, housing (D) 70 mm, and height (h) 6.00/9.50 mm. The A 109 designation refers to the lip and metal body geometry, which determines how the seal seats on the shaft and fits into the cavity. It is a sealing component for rotating shafts and lubricant chambers.

Typical applications include gearboxes, pumps, electric motors, rollers, and transmission equipment where oil or grease leaks must be stopped and bearings protected from the environment. You will also find it in agricultural machinery, conveyors, and process equipment. A worn seal allows lubricant loss and contaminant entry, which speeds up bearing failure, so replacement at every disassembly is good practice.

During installation, make sure the shaft is clean and free of burrs or marks, and that the sealing surface is not worn. Lubricate the lip before insertion and press the seal in perpendicular to the shaft using a tool that applies force on the outer edge. If the housing has a shoulder or radius, observe the correct installation depth. Selection depends on speed, temperature, and lubricant type; if you are unsure, contact us with your equipment details.

For an equivalent, send the full code, the shaft, housing, and height dimensions, and a photo or sample of the old seal. With that information we look for alternatives in the same brand or in others we supply. We can also advise if the A 109 design is not suitable and a different lip profile is needed.
