The DBH 5818 radial shaft seal is a lip seal that closes off the passage of lubricant and blocks the entry of dust and water on rotating shafts. Due to its dimensions of 12 mm shaft, 22 mm housing and 7 mm height, it is used in compact equipment: small electric motors, pumps, gearboxes and tools. MR Accesorios Industriales carries this brand and helps you confirm the size before quoting.

This item is a DBH 5818 radial shaft seal, with the following dimensions: 12 mm shaft diameter, 22 mm housing diameter and 7.00 mm height. The design is Lx, which indicates a single-lip configuration with spring. The 5818 code identifies the size and design within the DBH line. It is a small-section seal, intended for tight spaces where a taller seal does not fit.

Typical applications for a 12 x 22 x 7 mm oil seal are shafts of low-power electric motors, small centrifugal pumps, speed reducers, fans, pneumatic tools and light transmission equipment. In all cases it fulfills the function of retaining oil or grease inside the assembly and preventing contaminants from entering from outside, extending the life of bearings and gears.

To mount it, verify that the shaft and housing diameters match the indicated 12 mm and 22 mm. The shaft surface must be clean, without burrs or marks, and the housing free of old sealant residue. Lubricate the lip with the same grease or oil as the equipment before inserting it, and place the seal perpendicular to the shaft, without hitting it sideways. If the shaft is worn, evaluate a nearby size or a seal with an additional lip.

We work with in-house manufacturing in other areas, so we can advise you on the best option according to the application and the type of lubricant.
