The DBH 5267 seal is a radial seal with 20 mm shaft diameter, 40 mm housing and 4 mm height, with Lt design.

Its flexible lip runs on the shaft and maintains sealing under continuous rotation conditions. MR Accesorios Industriales carries this brand and advises you on choosing the right size.

This item is a DBH radial shaft seal, designation 5267. Its dimensions are 20.00 mm shaft diameter (d), 40.00 mm housing diameter (D) and 4.00 mm height (h). The Lt design corresponds to a single lip with spring, intended for rotating shafts with lubrication. The lip elastomer seals against the shaft and the metal case is press-fitted into the housing. It is a wear part: it is replaced when lubricant leakage or dirt ingress appears.

Typical applications for a seal of this size include small gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. It is also used on fan, mixer and conveyor shafts. In all cases, the function is the same: confine the oil or grease inside the assembly and prevent dust, water or particles from entering the bearing or gear. That is why it is found in industrial maintenance and machinery repair.

To install it, check that the shaft diameter is within tolerance and free of burrs and marks. Lubricate the lip before sliding it on and use a support tube that presses on the metal edge, never on the elastomer. The seal must sit perpendicular to the shaft. When selecting, take into account the rotation speed, working temperature and type of fluid. If the shaft is worn, consider a repair sleeve or an alternative size.

If you need an equivalent or a nearby size, send us the part number 5267 or the dimensions 20x40x4 mm by WhatsApp. We can look for alternatives in other brands or with different heights and diameters, always confirming the manufacturer's data sheet. We also advise you if the original seal has another designation or if the housing accepts variants. The idea is that you do not end up with equipment stopped because of a sealing part.
