The DBH 5821 oil seal is a radial seal with 26 mm shaft diameter, 42 mm housing bore and 10 mm height, with Lx design. It is used to retain lubricant and block the ingress of dust, water or particles in gearboxes, pumps, electric motors and transmission equipment. Its flexible lip runs on the rotating shaft and maintains sealing in continuous service. MR Accesorios Industriales supplies this brand and helps you confirm the size before requesting a quote.

The DBH 5821 is a single-lip radial shaft seal with the following dimensions: shaft diameter 26 mm, housing bore diameter 42 mm and height 10 mm. The Lx design corresponds to a seal with a sealing lip and metallic outer body, designed to be press-fitted into a cylindrical housing. These are the dimensions you must verify against the shaft and housing before ordering, because a seal with the same cross-section but a different design may not seal the same way.

Typical applications for a seal of this size are gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases the seal performs two functions: retaining oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used as a closure in bearings and bushings where the shaft rotates continuously and there is a risk of leakage.

To choose the right seal, in addition to the size, consider the shaft speed, working temperature and type of lubricant. The lip must rest on a ground shaft surface free of marks; if the shaft is worn, consider a seal with an offset lip or a wear sleeve. When installing, lubricate the lip and verify that it enters perpendicular to the housing to avoid damaging it.
