The DBH 5142 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 38 mm shaft diameter, 72 mm housing diameter and 12 mm height, and an Lx design, it is mounted in gearboxes, pumps, electric motors and power transmission equipment where lubricant must be retained and the ingress of dust or water stopped. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH 5142 radial shaft seal, identified by the code 5142. Its dimensions are 38.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 12.00 mm height (h). The Lx design indicates a single-lip configuration with a spring, intended for rotating shafts with lubrication. The elastomeric lip presses against the shaft and the spring maintains contact pressure; the metal body is press-fitted into the housing. This prevents oil leakage and the entry of contaminants.

Typical applications for a seal of these dimensions are found in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. It is also used in agricultural and industrial machinery where shafts rotate inside an oil-filled housing. In every case it performs the same function: retaining the lubricant inside and protecting the bearings or gears from external dirt.

For installation, check that the shaft diameter and the housing diameter match the 38 mm and 72 mm on the product page. The shaft surface must be clean, free of burrs and deep marks, and it is advisable to lubricate the lip before inserting it. The seal is fitted with the lip facing the lubricant side and is pressed in with a tube of the appropriate diameter, without striking the elastomer. If the shaft shows wear, consider a nearby size or a repair sleeve.
