The DBH 9429 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, 90 mm housing diameter and 8 mm height, and an Lx design, it is press-fitted into crankcases, covers and gearboxes to retain lubricant and stop the entry of dust and water. It is a wear part: when leakage appears, it is replaced by size.

This item is a seal from the DBH line, identified with part number 9429. Its dimensions are 38.00 mm shaft diameter (d), 90.00 mm housing diameter (D) and 8.00 mm height (h), with an Lx design. That combination defines the seat: the lip runs on a 38 mm shaft and the body fits into a machined 90 mm housing. The Lx design corresponds to a seal with a sealing lip and a construction configuration specific to that series, which should be verified against the manufacturer's product page before installation.

It is used in equipment where a shaft rotates inside a housing with lubricant: gearboxes, reducers, pumps, electric motors, rollers and drives. It also appears in applications exposed to dust or water, where the lip prevents the contaminant from entering the bearing or the oil bath. In maintenance, it is a common consumable: it is replaced when lubricant leakage is detected, when the lip hardens or when the shaft shows wear on the sealing surface.

To select the seal, the first step is to confirm the three dimensions: shaft diameter, housing diameter and height. Then, check the condition of the shaft: a scratched or worn surface means the new lip will not seal, even if the size is correct. During installation, the seal is inserted perpendicular and with uniform pressure, without striking the lip, and the edge is lubricated before the shaft enters. If the housing has burrs or the chamfer is damaged, it should be dressed to avoid cutting the seal.

If part number 9429 is not the one you need, or if the shaft or housing are worn and you want to evaluate a neighboring size, an equivalent can be found by the three dimensions and by the design type. For that, send the original part number, the shaft and housing dimensions, and a photo or sketch of the seat. With that data, it is compared against the available alternatives and it is determined whether the same size is best or another one that fits the housing.
