The DBH 8367/85 is a radial shaft seal of the Lx type, featuring a sealing lip and a metal case for press-fit into a machined bore. It measures 20 mm at the shaft, 39.80 mm at the housing, and 6.50 mm in height. This size is common in pumps, small motors, gearboxes, and power transmission units where installation space is tight. MR Industrial Accessories supplies the DBH brand and provides quotes via WhatsApp.

With a small shaft diameter and a medium housing bore, the 8367/85 suits low to medium speed shafts as long as the contact surface is ground and free from grooves. Its 6.50 mm height allows it to fit into thin covers or shallow housings. The Lx design combines a sealing lip with a metal body, making it suitable for machined cavities.

Typical applications include centrifugal and gear pumps, electric motors, gearboxes, compressors, mixers, and machine tools. It also appears on fan, agitator, and conveyor shafts. In these positions, the seal performs two tasks: it keeps oil or grease from escaping and blocks dust, water, or particles from reaching the bearings or bushings. As a wear part, the lip eventually hardens, cracks, or loses elasticity, leading to lubricant weeping.

When selecting a replacement, verify that the shaft and housing dimensions match those of the 8367/85 and that the height fits the cavity without deforming the lip. The shaft should have adequate hardness and surface finish, with no burrs or tool marks. Lubricating the lip before installation is recommended. For equipment exposed to heavy vibration, high temperatures, or dust, consider a different compound or a design with a dust lip. Press the seal evenly using a tube or spacer that contacts the outer diameter, never the lip.

To request a quote for the 8367/85, provide the part number and the dimensions of the old seal: shaft diameter, housing diameter, and height. With that information, we can locate an equivalent in DBH or another brand we carry. We can also cross-check the Lx design against the manufacturer's data sheet if you are unsure about the lip type or material. The more details you provide, the faster we can offer a suitable alternative.
