The DBH 5165Sil radial shaft seal is a lip seal that mounts in a component housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 28.00 mm shaft, 45.00 mm housing and 7.50 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment operating with shafts of that size.

This item is a radial shaft seal from the DBH line, identified as 5165Sil. Its dimensions are 28.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 7.50 mm height (h). The Lx design corresponds to the lip and seal body configuration. The lip elastomer works against the shaft with controlled interference, while the outer diameter maintains the fit in the housing. The 5165Sil designation makes it quick to locate in the catalogue and compare with other alternatives in the same family.

Seals of this size appear in equipment where a rotating shaft exits a crankcase or a lubricated housing. They are commonly found in gearboxes and gearmotors, centrifugal pumps, electric motors, mixers, conveyors and process machinery. They are also used in applications where water or dust must be kept out of the bearing, such as industrial washing machines, water treatment equipment or machines operating in dirty environments. In all cases, the seal protects the lubricant and extends bearing life.

To install a seal, check the condition of the shaft and housing: the shaft must not have burrs, deep scratches or wear in the contact area, and the housing must be clean and free of deformation. The lip is lubricated before installation and seated with a flat tool to avoid damaging it. Selection depends on speed, temperature and the fluid to be retained, as well as the type of elastomer. If the equipment operates with high vibration or misalignment, consider a stiffer design or a seal with a spring.

If you need a nearby size or an equivalent from another brand, send us the full part number, the shaft, housing and height dimensions, and a photo of the old seal if you have one. With that data we can look for the alternative within the DBH line or other brands we carry. We can also advise you on the most suitable lip design for the application. The goal is that you do not have to change the shaft or the housing to solve the replacement.
