The DBH 5528 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With a 38 mm shaft diameter, 54 mm housing diameter and 10 mm height, and Mz design, it is press-fitted into the housing and works on the shaft with the lip in contact. It is a wear part: when lubricant loss appears or dirt enters, it is replaced. MR Accesorios Industriales sells it as an official brand.

This item is a DBH radial shaft seal with designation 5528. Its dimensions are 38.00 mm shaft diameter, 54.00 mm housing diameter and 10.00 mm height. The Mz design corresponds to an oil seal with a sealing lip and metal body, intended for press fitting into the housing. The lip, generally made of elastomer, is what provides the dynamic seal against the shaft; the rigid body gives it the shape and the necessary interference to remain fixed in the housing. It is a small but critical part: the lubricant staying inside and contaminants staying outside depends on it.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, transmission shafts, rollers and process equipment. They appear both in new machines and in maintenance: when an oil seal starts to leak, the repair is usually simple and prevents greater damage to bearings and gears. In food, water treatment or general production plants, the oil seal also performs a containment function: it retains lubricant and limits the entry of dust, wash water or environmental particles.

To choose correctly, verify three things: the shaft diameter, the housing diameter and the height. All three values must match those of the original oil seal or the equipment data sheet. Also check the condition of the shaft surface: a scratched, worn or burred shaft ruins the new lip within a few hours. During assembly, lubricate the lip with the same grease or oil used in operation, insert it perpendicular to the shaft and tap evenly on the outer edge, never on the lip. If the housing has burrs, clean it before inserting the part.

If part number 5528 is not the one you need, or if the shaft is worn and you want to evaluate a neighboring size, send us the dimensions of the old oil seal or a photo of the part and the housing. With the shaft diameter, housing diameter and height we can look for the equivalent within the DBH line or suggest an alternative. We can also advise you on the type of lip or elastomer material according to the working fluid and temperature, always confirming against the manufacturer's data sheet.

MR Accesorios Industriales sells the DBH line as an official brand. If you already have part number 5528, write to us on WhatsApp and we will send you the quote. If you are unsure between two sizes, send us both and we will help you determine which one corresponds to your equipment.
