A radial shaft seal of the DBH 5401 type keeps lubricant inside a housing while blocking dust, water and particles from reaching the bearing area. Its Lz configuration pairs a main sealing lip with an outer dust lip, which suits equipment exposed to moderate contamination. Shaft 22.22 mm, housing 41.25 mm, width 11.11 mm. Gearboxes, pumps, motors and transmissions are common homes for this size.

Reading the code helps with selection. DBH identifies the seal family, 5401 is the reference for this particular size, and the Lz suffix tells you the lip arrangement: one lip seals against the shaft, a second lip sits outboard as a dust barrier. The elastomer compound and the internal spring are checked against the manufacturer's data before we quote, so the seal you receive matches the specification.

This size turns up wherever a shaft passes through a cover or housing and oil or grease has to stay put: gearboxes, centrifugal pumps, electric motors, compressors and transmission units, plus machine tools, washing equipment and conveyors. In every case the seal works alongside a bearing, bushing or housing that sets shaft concentricity, so the surrounding components matter as much as the seal itself.

Installation rewards care. Confirm the shaft and housing diameters match the values above, check the shaft for burrs or scoring, and clean the housing of old sealant. Lubricate the lip before sliding the seal into place, then drive it with a tube or socket that contacts the outer edge, tapping evenly and never pressing on the lip. Where vibration or misalignment is present, inspect the bearing and the shaft finish at the same time.

For a cross-reference, send code 5401 together with the shaft, housing and width dimensions you measured. That is enough for us to search the DBH line or another brand we supply for the closest match. If the dimensions are not available, the equipment model or the original seal code works too, and we will check it against our tables.
