The DBH 1246 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Thanks to its compact dimensions —17 mm shaft, 25 mm housing and 3.50 mm height— it is used in equipment where axial space is limited and rotation speed demands a flexible, well-seated lip. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

This item is a radial shaft seal from the DBH brand, identified by the code 1246. Its published attributes are: shaft diameter 17 mm, housing diameter 25 mm, height 3.50 mm and Lt design. The Lt design corresponds to a single-lip seal with spring, intended for rotating shafts with permanent lubrication. The 1246 nomenclature follows the manufacturer's size-based designation system: the first two digits indicate the shaft diameter and the next two the housing diameter, both in millimeters.

Typical applications for a seal of this size include small gearboxes, low-power electric motors, centrifugal pumps, compressors, machine tools and transmission equipment where oil or grease must be contained in a very tight axial space. It is also used in rollers, fan shafts and drive mechanisms that operate at moderate speeds and require protection against external contaminants.

To correctly select and install the seal, verify that the shaft and housing diameters match the values on the product page. The shaft must be ground, with suitable hardness and roughness, and the housing must have the entry chamfer so the lip is not damaged during installation. Lubricate the lip before inserting it, avoid striking it and make sure the spring is on the side of the fluid to be retained. If the equipment operates with heavy vibration or temperature, ask about material variants.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the code 1246 or the shaft, housing and height dimensions. With that data we can look for an alternative from the same brand or from another brand we supply, always respecting tolerances and lip design. We can also advise you if the space allows a taller seal or if a double-lip design is preferable.
