The DBH 6371Sil is a radial shaft seal built to keep oil and grease inside rotating equipment and to keep dust and moisture out. It fits a 44.45 mm shaft, a 66.62 mm housing bore and has a 16.70 mm height, with the Mx lip configuration. Because it is a wear item, it is normally replaced as soon as leakage or contamination shows up.

Reading the designation helps you confirm the fit before you order. The three figures in the code follow the usual order for this family: shaft 44.45 mm, housing 66.62 mm, height 16.70 mm. The Mx designation refers to a metal-cased seal with a flexible lip, the type that is pressed into the bore and rides against the shaft surface. Matching all three values against the old part or the housing drawing is the quickest way to avoid a wrong pick.

These seals show up in gearboxes, centrifugal pumps, electric motors, line shafts and other process equipment. They do two jobs at once: they hold lubricant in and they block dust, water and particles that would otherwise reach the bearings and gears. In food processing, chemical plants and water treatment, the lip material matters as much as the dimensions, since it has to tolerate the fluid and the temperature in service.

Installation is straightforward if the bore and shaft are prepared first. Check that the housing is clean, free of burrs and measures 66.62 mm, then coat the lip with the same oil or grease used in the unit. Drive the seal in with a tube or sleeve that presses on the outer diameter, never on the lip itself. The shaft contact area should be smooth and free of grooves. If a previous seal has already failed, it is worth checking bearing clearance and the running temperature at the same time.

When you need a replacement or a cross, send part number 6371Sil together with the shaft, housing and height figures. A photo of the old seal or the housing drawing also works. Our team checks the data against the manufacturer's sheet and can suggest options within the same radial seal category, keeping the design and material in mind.

If you are unsure about the application, the surface speed or the lubricant in use, ask before installing. A seal that does not suit the service can fail quickly and take the bearing with it. Send part number 6371Sil by WhatsApp or email and we will prepare your quote.
