The DBH 8156 is a radial shaft seal that fits a 25.40 mm shaft, a 38.07 mm housing and has a 6.66 mm height. Its Mx design uses a single lip with a spring, so it retains oil or grease while keeping dust and moisture out. This makes it a practical replacement for inch-based shafts in gearboxes, pumps and motors, and MR supplies it along with the tools and lubricants needed for installation.

The seal is built with an elastomeric lip and a metal case. The metal case holds the seal firmly in the housing, while the spring-loaded lip maintains contact against the rotating shaft. The Mx design is a single-lip, spring-loaded configuration intended for rotating shaft applications.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission equipment. It is also common in agricultural and industrial machinery where shafts turn on bearings and lubricant must stay in while contaminants stay out. Because the shaft size is 25.40 mm, it matches one-inch shafts often found in equipment of US origin or in standard shaft replacements.

Before installation, inspect the shaft for burrs, scratches or wear and make sure the housing is clean and round. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in squarely with a proper mounting tube. Do not strike the lip or the spring. When choosing a seal, consider shaft speed, operating temperature and the fluid being sealed. If the shaft has a worn track, an offset lip or a repair sleeve may be needed.
