The DBH 5347 radial shaft seal is a lip seal that mounts in the housing and seals against the shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 49.20 mm shaft, 69.88 mm housing and 9.52 mm height place it in equipment with medium-section shafts. It is a wear part: when the lip hardens or an oil leak appears, it is replaced with a new one. MR Accesorios Industriales carries this brand and helps you confirm the size.

This item is a DBH brand oil seal, part number 5347, with the following dimensions: shaft diameter 49.2 mm, housing diameter 69.88 mm and height 9.52 mm. The indicated design is Lx, which corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The sealing lip bears on the shaft and the outer diameter fits into the housing; the 9.52 mm height defines the width of the cavity it fits into. It is not a double-lip seal or a unit with a reinforced metal case: it is the standard version of the series.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, drive shafts and process equipment where a shaft rotates inside a housing and the oil needs to be separated from the environment. They also appear in agricultural machinery, washing equipment and conveying systems. The function is twofold: retain the lubricant on the inner side and prevent contaminants from entering on the outer side. When the seal fails, oil loss or the entry of dirt accelerates the wear of bearings and gears.

To select the replacement, verify that the shaft diameter, housing diameter and height match those of the original seal. The Lx design defines the lip type and the spring; if the equipment runs at high peripheral speed or high temperatures, it is advisable to check the lip material and the type of lubricant. During installation, clean the housing and the shaft, lubricate the lip with the same oil used in the equipment and seat the seal perpendicular, without striking it from the side. A lip installed crooked or over a scratched shaft will leak even if the size is correct.

If part number 5347 does not appear on your list or you need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part. With that data we look for the equivalent in the same brand or in another line we carry. We can also verify whether the Lx design is suitable for your application or whether it is better to move to a seal with a different lip geometry. The more complete the information, the faster we can give you a concrete alternative.
