The DBH 6894Pol is a radial shaft seal built to design A 023-R. It sits between a turning shaft and its housing, holding lubricant in and keeping dust, water and particles out. With a 75 mm shaft, a 100 mm housing bore and a 12/13 mm height, it suits gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies this DBH reference through its seals and oil seals line.

The reference breaks down simply: DBH is the brand, 6894Pol is its commercial code for this size, and A 023-R describes a single sealing lip on a metal case. The 12/13 mm height points to a taller profile, either a double-height lip or a version that carries an integrated dust lip. Treat the code as a starting point and confirm it against the part you are removing before you order.

You will run into this size wherever a 75 mm shaft turns inside a 100 mm bore: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. The seal does two jobs at once, retaining the oil or grease in the assembly and shutting out what comes from outside. Where dust, washdown water or chips are present, the lip has to ride on a shaft that is ground and lubricated so contact stays even.

Installation starts with the shaft. Look for burrs, deep wear marks and check that hardness and roughness are suitable. The bore should be clean, round and free of dents, at the correct diameter. Coat the lip with the same oil or grease the equipment uses, set the seal square to the shaft and press it home with a tube or spacer that pushes on the outer ring, never on the lip. A worn shaft track can often be handled by setting the seal at a different depth or fitting a repair sleeve.

For an equivalent, send the code 6894Pol together with the shaft, housing and height measurements and a note on the application. A photo of the old seal or the housing drawing works just as well. From that we match the DBH reference or find an alternative with the same geometry. Where there is room, we can also look at options with an extra lip or a dust lip.
