The DBH 1348 oil seal is a radial shaft seal with an A 378 design that fits a 90 mm housing and has a 12.00 mm height. It keeps lubricant in and contaminants out, protecting bearings, bushings and shafts in gearboxes, pumps, motors and other rotating equipment.

The 1348 designation identifies this radial shaft seal from the DBH line. Its key dimensions are housing 90 mm and height 12.00 mm. The A 378 design specifies the lip profile and case style. Always confirm these dimensions against the original component before ordering, since fit and sealing depend on them.

Radial shaft seals separate a lubricated environment from one exposed to dirt or moisture. They are common in gearboxes, centrifugal pumps, electric motors, spindles and belt or chain drives. They also serve as closures in machine tool bearings and continuous process equipment, where leaks or contamination shorten bearing life.

Installation requires a clean shaft and housing, free of burrs or marks. Lubricate the lip before insertion and seat the seal with a tube of the correct diameter to avoid damage. Selection depends on rotation speed, service temperature and the fluid being retained. If the shaft is worn, consider a repair sleeve or an alternative size. The A 378 design indicates the lip and spring type, but always verify against the manufacturer's data.

For an equivalent seal, send the code 1348 along with the shaft, housing and height dimensions. We can search for an alternative within the DBH line or from other brands we supply. We also advise if housing or shaft tolerances fall outside standard ranges, so you choose the best option for your equipment.
