This item is a radial shaft seal from the DBH line, identified with code 9833. Its dimensions are 21 mm shaft diameter (d), 29 mm housing diameter (D) and 8.00 mm height (h). The Ls design corresponds to a seal with a single sealing lip and outer metal body, designed to be press-fitted into a cylindrical housing. The manufacturer's nomenclature summarizes the size: 21 x 29 x 8 mm. It is a common replacement part in equipment where axial space is limited.

Typical applications for a seal of this size include small gearboxes, centrifugal pumps, low-power electric motors, rollers and transmission shafts. In all cases it serves two functions: retaining the oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used as a barrier in equipment subject to washing or dusty environments, provided the lip material is compatible with the fluid and working temperature.

To select the seal correctly, check that the shaft and housing diameters match the values on the data sheet. The shaft must be within tolerance, without burrs or deep marks in the contact area, and the housing must have the entry chamfer so the lip is not damaged during installation. Lubricate the lip before inserting it and seat the part perpendicular to the shaft. If the equipment operates with high vibration or temperature, ask about material variants.

If you need an equivalent from another brand, send us code 9833 or the dimensions 21 x 29 x 8 mm and the Ls design. With that data we can look for alternatives within the same radial shaft seal category, always respecting the shaft and housing diameters. It is also advisable to indicate the type of fluid and the service temperature to guide the choice of lip compound.
