The DBH 5669 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. With an 18 mm shaft, 31.75 mm housing bore and 3.57 mm overall width, it fits where axial room is tight. Treat it as a wear item: replace it when leakage or unusual noise appears.

This seal carries the DBH brand and part number 5669. Its dimensions are shaft 18 mm, housing 31.75 mm and width 3.57 mm. The Mt design means a single sealing lip in a metal case, press-fitted into a cylindrical housing. The lip runs against the shaft while the case holds the seal in the bore.

You will find it in small electric motors, gearboxes, pumps, fans, transmission shafts and low-power machines that rotate continuously and must retain oil or grease. Automotive, agricultural and industrial assemblies with limited axial space also use it. Its job is to shield bearings and gears from dust, water and particles.

To select the right seal, confirm that the shaft and housing diameters match the values above. Install on a clean shaft free of burrs or marks, lubricate the lip before insertion, and make sure the housing has a proper chamfer so the lip is not damaged. If the shaft is worn, consider a seal with an auxiliary lip.

If you need an equivalent or a different size, send part number 5669 or the current seal dimensions by WhatsApp. We cross-check the designation against the manufacturer's data and offer alternatives within the same radial seal category. We can also advise on unusual housing or shaft tolerances.
