With a 55 mm shaft diameter, 70 mm housing and a height of 6.00/9.50 mm, it is a replacement part for equipment with medium-section shafts. MR Accesorios Industriales supplies this brand and advises you so that you choose the correct oil seal for your application.

This item is a DBH 8312 radial shaft seal, identified by its designation 8312. Its dimensions are shaft (d) 55 mm, housing (D) 70 mm and height (h) 6.00/9.50 mm. The A 109 design corresponds to the geometry of the lip and the metal body, which defines how it seats on the shaft and how it fits into the cavity. It is a sealing component intended for rotating shafts and lubricant chambers.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where oil or grease leaks must be prevented and bearings protected from the environment. It also appears in agricultural machinery, conveyors and process equipment. When the oil seal wears, loss of lubricant and ingress of contaminants accelerate bearing failure, so it should be replaced at every disassembly.

To install it, verify that the shaft is clean, free of burrs or marks, and that the sealing surface is not worn. Lubricate the lip before inserting it and place the oil seal perpendicular to the shaft, using a tool that presses on the outer edge. If the housing has a shoulder or radius, respect the installation depth. Selection depends on speed, temperature and type of lubricant; if you have doubts, contact us with your equipment data.

If you need an equivalent or a nearby size, send us the full code, the shaft, housing and height dimensions, and a photo or sample of the old oil seal. With that data we look for alternatives in the same brand or in others we supply. We can also guide you if the A 109 design is not suitable for your application and a different lip profile is needed.
