The DBH 1224/85 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. Its A 392 design and stepped height of 5.50/10.00 mm make it suitable for housings with a shoulder or for covering two mounting positions. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with 20 mm shafts and 47 mm housings.

This item is a DBH brand oil seal, identified by the designation 1224/85. Its dimensions are 20 mm shaft, 47 mm housing and 5.50/10.00 mm height. The A 392 design corresponds to a profile with a sealing lip and stepped height: the 5.50 mm section seats in the housing and the 10.00 mm section covers the shoulder or flange. The lip, generally made of elastomer, runs on the shaft with a slight interference to ensure the seal.

Typical applications for an oil seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. It is also found in machine tools, industrial washing equipment and hydraulic systems where oil or grease must be contained and external contamination prevented. Its stepped height allows it to be adapted to housings with a shoulder or to covers requiring a larger sealing surface.

To install a radial shaft seal, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Fit it with the lip facing the fluid to be retained and press evenly, without striking the elastomer. If the housing has a shoulder, orient the taller section toward that shoulder. If in doubt, consult the manufacturer's data sheet or contact MR Accesorios Industriales.

If you need an equivalent or a nearby size, have the code 1224/85 and the shaft, housing and height dimensions on hand. With that data we can search the DBH line or other brands we carry. We can also advise you if the mounting space accepts a standard height or if a design with a spring or double lip is preferable. The goal is for the seal to do its job without modifying the equipment.
