The DBH 5267Sil is a radial shaft seal from the DBH line, built to keep lubricant in and contaminants out of rotating shaft assemblies. It measures 20 mm at the shaft, 40 mm at the housing and 4.00 mm in height. That slim profile makes it a practical choice where axial room is tight. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

The part number 5267Sil identifies a single-lip seal in the Lt design. The three dimensions to check before ordering are shaft diameter (d) 20 mm, housing bore (D) 40 mm and overall height (h) 4.00 mm. The Lt configuration suits lubricated running at moderate speeds. Lip compound and elastomer should be verified against the manufacturer's data sheet for your specific fluid and temperature. Confirm that the housing bore and depth match the seal before installation to avoid leaks.

You will find this size in small electric motors, gear reducers, pumps, compressors and power transmission units. It also appears in farm equipment, pneumatic tools and bearing arrangements where the shaft passes through a housing. The compact cross-section fits assemblies with limited space that still need a reliable dirt barrier. In dusty or wet surroundings, consider a seal with a secondary lip or a more resistant elastomer.

Selection depends on shaft speed, operating temperature and the lubricant in use. The Lt design works well on medium-speed shafts with continuous lubrication. Before fitting, inspect the shaft for burrs or scratches that could cut the lip, and apply lubricant to the lip. Press the seal into the housing squarely, without hitting it directly. If the shaft is worn, a repair sleeve or a different seal size may be required.

For an equivalent, send us the original part number, your shaft and housing dimensions, and a photo of the part if you have one. We can suggest alternatives from other brands that fit your equipment. MR Industrial Accessories helps you identify the best option.
