The DBH 8738 is a radial shaft seal from the DBH line, sized for a 12 mm shaft, a 25.40 mm housing bore, and an 8.00 mm width. Its Lx design uses a single lip with a spring, so it holds lubricant in and keeps dust, water, and other particles out. This makes it a practical choice for small-diameter shafts turning at moderate speeds. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

The code 8738 identifies a DBH radial shaft seal. The published dimensions are: shaft 12 mm, housing 25.40 mm, width 8.00 mm. The Lx design is a single-lip, spring-loaded configuration for rotating shafts that need lubrication. The lip rides on the shaft while the outer case presses into the housing bore. It is a common replacement part wherever oil or grease must stay in and contamination must stay out.

Seals of this size often appear in small gearboxes, pumps, electric motors, compressors, machine tools, and drive units. They also show up on fan, mixer, and conveyor shafts where a rotating shaft passes through a fixed housing. In each case, the seal separates the lubricant from the surrounding environment and shields nearby bearings or bushings. If the equipment sees heavy dirt or water, check whether the Lx design suits those conditions.

Before installing a radial shaft seal, inspect the shaft for burrs, wear, and correct roughness. The housing must be clean and free of deformation. Lubricate the lip before insertion and use a tool that presses on the outer case, never on the lip. Selection depends on speed, temperature, and the fluid being sealed. If the shaft has a deep groove, you may need a seal that positions the lip in a different spot or a shaft repair.

For an equivalent to the DBH 8738, send the full code, the brand, and the shaft, housing, and width dimensions. With that information we can search other brands or confirm whether the Lx design is correct. We can also help if the original seal has no visible markings. The more details you provide — equipment type, fluid, and operating conditions — the more accurate the match.
