The DBH 8712Pol radial shaft seal is a lip seal designed for 22 mm rotating shafts, with a 40 mm housing bore and 8 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear. It is fitted in gearboxes, pumps, electric motors and power transmission equipment operating with continuous rotary motion. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct size.

This item is a radial shaft seal of Kx-R-H design, with the following dimensions: shaft diameter (d) 22 mm, housing bore diameter (D) 40 mm and height (h) 8.00 mm. The Kx-R-H design corresponds to a radial shaft seal with a sealing lip and reinforced body, suitable for rotating lubricated shafts. The designation 8712Pol identifies the size and construction type within the DBH line. Before fitting, check that the three dimensions match the housing and shaft of your equipment.

Typical applications of a 22 x 40 x 8 mm radial shaft seal include gearboxes, centrifugal pumps, low-power electric motors, rollers and transmission shafts. In all cases it works on a shaft rotating inside a fixed housing, separating the oil or grease from the outside environment. It is also used in equipment exposed to water or dust splash, because the lip prevents contaminants from reaching the bearings and bushings.

When selecting and fitting this radial shaft seal, take the condition of the shaft into account: the sealing surface must be smooth, free of grooves and burrs, and with adequate hardness to prevent premature wear. The housing must have the diameter and depth shown on the product page. Lubricate the lip before inserting it and fit the radial shaft seal with a flat driver so as not to damage the spring. If the shaft shows wear, consider a repair sleeve or an alternative size.
