The DBH 1404 oil seal is a single-lip radial seal that stops lubricant from escaping and blocks dust, water and particles from entering rotating shafts. With a 21.50 mm shaft diameter, 36.00 mm housing diameter and 8.00 mm height, it is press-fitted into covers, gearboxes and housings to protect bearings and bushings. It is a wear part: when oil loss appears or the lip hardens, it is replaced. MR Accesorios Industriales supplies it as an official brand DBH product.

The 1404 is a design A oil seal: single sealing lip with an outer metal case and vulcanized elastomer. Its dimensions are 21.50 mm shaft diameter (d), 36.00 mm housing diameter (D) and 8.00 mm height (h). The lip runs on the shaft with slight interference and an internal spring that maintains contact pressure; the outer case seats in the housing and seals by interference. That combination stops oil or grease from leaking out and contaminants from getting in.

It is used in gearboxes, pumps, electric motors, transmission shafts, rollers and process equipment where a shaft rotates inside a lubricated housing. It also appears in low and medium speed applications exposed to dust, chips or wash water. In all those cases it performs the same function: separating the lubricated side from the environment and extending the life of the bearing or bushing behind the seal.

To select a radial shaft seal, the first step is to confirm the three dimensions: shaft diameter, housing diameter and height. Then the condition of the shaft surface: it must be smooth, with no grooves or burrs, because the lip wears quickly against a rough surface. During installation, lubricate the lip, seat the seal squarely and tap evenly on the metal edge, never on the elastomer. If the housing has burrs, clean them before seating the part.

If the 1404 is not the size you need, send us the old part number, the dimensions measured with a caliper or a photo of the seal and the housing. We look for the equivalent in the same series or a nearby size within the lines we carry. The more data you give us — shaft diameter, housing, height and type of lubricant — the faster we can offer you the right alternative.
