The DBH 8367/85 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 20 mm shaft diameter, 39.80 mm housing diameter and 6.50 mm height, this compact size appears in pumps, small motors, gearboxes and power transmission equipment where space is limited. MR carries the DBH brand and quotes it on WhatsApp.

The DBH 8367/85 is an Lx design oil seal, with a sealing lip and metal body for installation in a machined cavity. Its dimensions are 20 mm shaft diameter (d), 39.80 mm housing diameter (D) and 6.50 mm height (h). That combination of a small shaft and a medium housing makes it suitable for low and medium speed shafts, provided the contact surface is ground and free of grooves. The 6.50 mm height allows it to be mounted in thin covers or housings with little depth.

It is used in equipment where two environments must be separated: centrifugal and gear pumps, electric motors, gearboxes, compressors, mixers and machine tools. It also appears on fan, agitator and conveyor shafts. In all cases it performs two functions at once: it prevents oil or grease from leaking out and stops contaminants from entering toward the bearings or bushings. It is a wear part: over time the lip hardens, becomes marked or loses elasticity, and that is when it starts to weep lubricant.

To select it, check that the shaft diameter and housing diameter match those of the 8367/85 and that the height fits into the cavity without deforming the lip. The shaft must have adequate hardness and roughness, with no burrs or tool marks, and it is advisable to lubricate the lip before mounting. If the equipment operates with heavy vibration, temperature or dust exposure, consider a different compound or a design with a dust lip. Mounting pressure must be even, with a tube or spacer that bears on the outer diameter, never on the lip.
