The DBH 1172 oil seal is a radial shaft seal with A 378 design that mounts in housings of 130 mm diameter and 12 mm height. Its function is to retain lubricant and exclude contaminants in rotating equipment, protecting bearings and shafts. It is a common replacement part in industrial maintenance, where correct size selection prevents leaks and premature wear. MR Accesorios Industriales carries this brand and advises you so you can request the exact seal for your equipment.

This item corresponds to a DBH radial shaft seal with designation 1172. According to the product page data, the housing has a diameter of 130.00 mm and the total height is 12.00 mm. The A 378 design defines the lip and metal body geometry. It is advisable to confirm the shaft against the manufacturer's data sheet or consult us with the original measurement.

Radial shaft seals like this one are used in gearboxes, pumps, electric motors, rollers and transmission equipment. Their job is twofold: retain the oil or grease inside the assembly and prevent dust, water or particles from entering the bearing. In industrial plants, a worn seal causes lubricant loss and accelerated wear. Therefore, when replacing, the same height and housing diameter are sought, along with a lip compatible with the type of lubricant and the equipment speed.

To install a DBH 1172 oil seal, keep in mind the cleanliness of the housing and shaft, and the use of an installation tool that presses on the outer edge, never on the lip. Before placing it, lubricate the lip with the same oil as the equipment. If the housing has burrs or the shaft shows wear, the seal will not seal properly. When selecting, verify that the outer diameter and height match those of the original seal, and that the A 378 design is compatible with the available space.
