The DBH 8743 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing. It is used in gearboxes, pumps, electric motors and power transmission equipment to retain lubricant and stop dust or water from entering. Its size of 47 mm shaft, 81.02 mm housing and 17 mm height places it in medium-sized equipment. MR Accesorios Industriales sells it as an official brand.

This item is a radial shaft seal from the DBH brand, identified by part number 8743. Its dimensions are 47 mm shaft diameter, 81.02 mm housing diameter and 17.00 mm height. The design indicated on the product page is Lx, which corresponds to a single-lip seal with a metal case and sealing lip. It is a standard replacement part for rotating shafts and is press-fitted into the housing, with the lip resting on the shaft surface.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases it serves the same function: keeping lubricant inside the assembly and preventing contaminants from entering from outside. It is also used as a secondary seal in equipment where two environments with different pressure or different fluid must be separated.

To select and install a seal, you must verify that the shaft diameter, housing diameter and height match those of the original housing. The shaft must be clean, free of burrs and deep marks in the contact area, and it is advisable to lubricate the lip before inserting it. The part is positioned perpendicular to the shaft and is seated with a suitable tube or driver, never by striking the lip directly. If the housing has a shoulder, the mounting direction must be respected.

If you need a nearby size or an equivalent to part number 8743, the most practical approach is to send us the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same family or from another brand we carry. The code engraved on the part or the model of the equipment where it is mounted also helps, so we can cross-reference the information with the manufacturer's data sheet.
