The DBH 1224/85 is a radial shaft seal that keeps lubricant in and contaminants out. It mounts on a 20 mm shaft and seats in a 47 mm housing, with a stepped height of 5.50/10.00 mm. The A 392 profile combines a sealing lip with two height levels, so it fits housings that have a shoulder or covers that need a wider sealing surface. You will find it in gearboxes, pumps, electric motors and other power transmission equipment.

The code 1224/85 identifies this DBH oil seal. Its dimensions are shaft 20 mm, housing 47 mm, height 5.50/10.00 mm, and the design is A 392. The stepped height works in two sections: the 5.50 mm portion sits in the housing bore, while the 10.00 mm portion covers a shoulder or flange. The elastomer lip runs against the shaft with a slight interference fit to hold the seal.

Seals of this size appear in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drives. They are also common in machine tools, industrial washing equipment and hydraulic systems where oil or grease must stay inside and dust, water or particles must stay out. The stepped height lets the same part suit a shouldered housing or a cover that needs more sealing surface.

Before installation, confirm that the shaft and housing are clean and free of burrs or scratches. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in evenly without striking the elastomer. The lip should face the fluid being retained. If the housing has a shoulder, orient the taller section toward it. When in doubt, check the manufacturer's data sheet or ask our team.

For an equivalent, have the code 1224/85 and the shaft, housing and height dimensions ready. With that information we can look through the DBH line or other brands we supply. We can also tell you whether the mounting space accepts a standard height or whether a spring-loaded or double-lip design is a better fit, so the seal works without modifying the equipment.
