The DBH 9581/85 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. With dimensions of 22 mm shaft, 31 mm housing and 6.50 mm height, it is press-fitted into covers, gearboxes and pumps. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified by the designation 9581/85. Its dimensions are 22 mm shaft diameter (d), 31 mm housing diameter (D) and 6.50 mm height (h). The A 243 design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip works on the shaft race and the outer body fits into the housing to ensure sealing. It is a common replacement part in equipment with continuous rotating motion.

Typical applications for a seal of these dimensions include gearboxes, electric motors, centrifugal pumps, compressors, transmission shafts and machine tools. It is generally located at the shaft outlet, where it separates the lubricated interior from the environment. It is also used in conveying equipment and speed reducers. If the seal fails, oil loss, contaminant ingress and noise appear; therefore it should be checked at every preventive maintenance interval.

For proper installation, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The 6.50 mm height defines the space available in the housing: if the housing is deeper, the seal may sit offset and fail to seal. The designation 9581/85 and the A 243 design are the data you must cross-check with the manufacturer's product page to confirm compatibility.

If you need an equivalent or a nearby size, send us the code 9581/85 along with the shaft, housing and height dimensions. You can also send us a photo of the old seal or the housing drawing. With that data we look for alternatives within the same brand or from other lines we supply. Do not improvise with approximate dimensions: a seal that does not fit can damage the shaft or the bearing within a few hours of running.
