The DBH 5267Sil radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of contaminants such as dust, water or particles. With dimensions of 20 mm shaft diameter, 40 mm housing and 4 mm height, it is used in equipment where axial space is limited. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by part number 5267Sil. Its dimensions are: shaft diameter (d) 20 mm, housing diameter (D) 40 mm and height (h) 4.00 mm. The Lt design corresponds to a single-lip configuration, suitable for applications with lubrication and moderate speeds. The lip material and elastomer are confirmed against the manufacturer's data sheet. It is important to verify that the housing has the correct diameter and depth for a leak-free installation.

Typical applications for this seal include small electric motors, gear reducers, pumps, compressors and power transmission equipment. It is also used in agricultural machinery, pneumatic tools and bearing systems where the shaft passage needs to be sealed. Because of its compact size, it is common in assemblies where space is limited and an effective barrier against dirt is required. If the equipment operates in environments with a lot of dust or moisture, it is advisable to evaluate a seal with an additional lip or a more resistant material.

To select this seal correctly, take into account the rotation speed, working temperature and type of lubricant. The Lt design is appropriate for shafts rotating at medium speeds with continuous lubrication. During installation, make sure the shaft has no burrs or marks that could damage the lip, and lubricate the lip before inserting it. The seal must be press-fitted into the housing, without striking it directly. If the shaft shows wear, a repair sleeve may be needed or the seal size may have to be changed.
