The DBH 8690 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Due to its compact size and Lz design, it is used in equipment where axial space is limited and a reliable seal is required. MR Accesorios Industriales offers it as part of its line of seals and oil seals for maintenance and replacement.

This item is a DBH radial shaft seal identified with the designation 8690. Its dimensions are 25.00 mm shaft diameter, 38.00 mm housing diameter and 6.40 mm height. The indicated design is Lz, which corresponds to a single lip configuration with spring. These values are those listed on the product page and are the ones you must compare before replacing a part.

Seals of this size are found in gearboxes, pumps, electric motors, fans and power transmission equipment. They also appear in machine tools, compressors and hydraulic systems where oil or grease must be contained at the point where the shaft passes through the housing. In all these cases, the seal works together with a rotating shaft and a fixed housing, and its function is to prevent leaks and contamination.

To select the replacement, verify that the shaft diameter, housing diameter and height match those of the original seal. Also check the condition of the shaft: a scratched or worn surface prevents the lip from sealing properly, even if the size is correct. During installation, lubricate the lip with the same oil or grease used in the equipment and place the seal perpendicular to the shaft, without striking it directly. If the housing has burrs, clean it before inserting.
