The DBH 8418 oil seal is a radial shaft seal with a 40 mm shaft, 55 mm housing and 9.50 mm height, in Mx-Bidi design. It is used to retain lubricant and exclude contaminants in rotating equipment such as pumps, electric motors, gearboxes and rollers. Its flexible lip runs on the rotating shaft and maintains sealing in both directions. MR Accesorios Industriales supplies this official brand and advises you on choosing the right size for your equipment.

The DBH 8418 is a radial shaft seal with the following dimensions: shaft diameter 40 mm, housing diameter 55 mm and height 9.50 mm. Its Mx-Bidi design indicates that the lip is prepared to seal in both directions of rotation, which is useful when the shaft can rotate in either direction or when there is alternating pressure. The outer body is made of elastomer and the lip works with a spring that ensures constant contact on the shaft.

This type of oil seal is mounted on equipment where oil or grease leaks must be prevented while also keeping out dust or water. It is common in centrifugal pumps, electric motors, gearboxes, conveyor rollers, mixers and machine tools. It is also used as a secondary seal in transmission cases and in applications with shafts rotating at moderate speeds and temperatures within the usual range for elastomers.

To install it correctly, check that the shaft has no burrs or wear and that the surface where the lip rests is clean and lubricated. The housing must be in good condition and have the correct diameter so that the seal presses in without deforming. If the shaft shows a marked wear track, it is advisable to evaluate a nearby size or a seal with the lip in a different position. The selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a nearby size, send us the code 8418 or the dimensions of your current seal: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same brand or another line we supply. We can also advise you if the Mx-Bidi design is not suitable for your application and it is better to switch to a single-lip seal or another geometry.
