The DBH 5751 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing, while at the same time preventing dust and contaminants from entering. It is used in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained at a rotating point. Its dimensions correspond to a 108 mm shaft, a 142.88 mm housing and a 12.70 mm height.

This item is a shaft seal of Lz design, with the following mounting dimensions: shaft diameter (d) of 108 mm, housing diameter (D) of 142.88 mm and height (h) of 12.70 mm. The Lz design corresponds to a single-lip seal with a spring, intended for rotating shafts with lubrication. Before mounting it, check that these three dimensions match your equipment's housing and shaft, because a seal of another size will not seal even if it looks similar at first glance.

Typical applications for a seal of this size are gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment where the shaft rotates inside a machined housing. It also appears in old or imported machines, where the exact inch or millimeter size is not always available in standard lines and the manufacturer's specific part number has to be found.

To select and mount a radial shaft seal, take into account the shaft speed, the working temperature and the type of lubricant. The lip must rest on a shaft surface free of scratches or wear, and it is advisable to lubricate the lip before inserting it. The seal is mounted with the lip facing the side of the fluid to be retained, and it is seated square with a tube or shim that does not damage the seal. If the housing has burrs, clean it before installing.

If you need an equivalent or a nearby size, send us part number 5751 together with the shaft and housing dimensions, and a photo or sketch of the old seal. With that data we can look for an alternative from the same brand or another line that fits the mounting. We can also check whether the size corresponds to a series with height or lip design variants.
