The DBH 8837 radial shaft seal is a lip seal designed for 10 mm shafts, with a 20 mm housing bore and 5 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles, protecting bearings and bushings in rotating equipment. It is press-fitted into the housing and runs on the moving shaft, so correct selection of size and material defines its service life. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified by the code 8837. Its nominal dimensions are 10 mm shaft, 20 mm housing bore and 5.00 mm height, with an Lx design. That combination defines a compact-section seal, intended for tight spaces where the lip must run on a small-diameter shaft. The Lx design corresponds to a single-lip configuration with spring, suitable for retaining oil or grease in low and medium-demand applications.

Typical applications of a 10 x 20 x 5 mm oil seal include small electric motors, gear reducers, pumps, fans, light transmission boxes and automation equipment. It also appears in machine tools, compressors and irrigation or washing systems where the goal is to prevent lubricant leaks and the entry of contaminants. In all cases it is advisable to verify that the shaft has no burrs or wear on the contact track, because that accelerates lip failure.

To install this seal, clean the housing and the shaft, lubricate the lip with the same oil used in the equipment and press perpendicularly until it seats at the bottom. Do not strike the lip or install it inverted. When selecting, take into account the shaft speed, working temperature and the fluid to be retained: the lip and spring material must be compatible. If the equipment runs with high vibration or eccentricity, consider a stiffer design or a seal with an auxiliary lip.
