The DBH 5174 oil seal is a single-lip radial shaft seal that mounts on a 38 mm shaft and fits into a 55.25 mm diameter bore, with a 9.00 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment that operates with oil or grease.

This DBH 5174 oil seal has an Lx design: a sealing lip that runs on the shaft and a metal case that is press-fitted into the housing. The dimensions listed on the product page are a 38 mm shaft, a 55.25 mm housing and a 9.00 mm height. The lip is designed to run against a machined and ground surface, with a film of lubricant that reduces friction and dissipates heat.

Typical applications for this type of oil seal are gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission shafts. In every case it serves the same function: confining the oil or grease inside the equipment and blocking the entry of external contaminants. It is a wear part, so it should be inspected when leaks appear or when the equipment is disassembled for maintenance.

To install it, check that the shaft has no burrs or deep marks and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a flat driver that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a neighboring size or a seal with an auxiliary lip. The selection depends on speed, temperature and the type of lubricant.

If you need an equivalent or a different size, send us code 5174 along with the shaft and housing dimensions, a photo of the old part and the type of lubricant the equipment uses. With that data we can look for an alternative within the DBH line or from other brands we carry. We can also advise you if the original seal is no longer available and a standard size has to be adapted.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you want a quote or to ask about a neighboring size, write to us on WhatsApp with code 5174 and we will reply with the technical information you need to make your purchase decision.
