The DBH 5256 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. Thanks to its dimensions of 25 mm shaft, 35 mm housing and 7 mm height, and its Lz design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a DBH 5256 radial shaft seal, identified by part number 5256. Its attributes are: shaft diameter 25 mm, housing diameter 35 mm, height 7.00 mm and Lz design. The Lz design corresponds to a seal with a sealing lip and spring, intended to retain lubricant and exclude contaminants on rotating shafts. Always check that these three dimensions match the shaft and housing of your equipment before ordering it.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, reducers and transmission equipment. In these assemblies, the seal prevents oil leaks and the entry of dust or water, which extends the life of bearings and gears. It is a wear part: it should be replaced when leaks appear or when the equipment is disassembled for another repair.

To install it, clean the housing and the shaft, check that there are no burrs or marks that could damage the lip, and lubricate the lip with the same oil or grease used in the equipment. The seal is inserted perpendicular to the shaft, without striking it unevenly. When selecting a replacement, in addition to the dimensions, take into account the type of lubricant, the working temperature and the shaft speed; if this data is not on the product page, check with the manufacturer.
