For maintenance and purchasing teams working on gearboxes, pumps and similar rotating equipment, the DBH 5742 is a radial shaft seal that keeps lubricant in and contaminants out. It is sized for a 77.80 mm shaft, a 111.02 mm housing bore and a 14.28 mm overall height, and it uses the Lz lip and metal body configuration. MR Industrial Accessories LLC supplies this seal and can help you confirm the correct variant for your application.

The seal carries the designation 5742. Its three key dimensions are: shaft 77.80 mm, housing 111.02 mm, width 14.28 mm. The Lz design refers to the lip geometry and the metal case, which is intended for continuous contact with lubrication present. This is a standard replacement item in the seal range MR distributes.

Seals in this size range show up in gear reducers, pumps, electric motors, line shafts and process machinery where oil has to be kept separate from the surrounding environment. They are also common on conveyors, agricultural implements and pumping systems that see dust or moisture. In each case the seal shields the bearings and stops leaks that would otherwise contaminate the area and trigger unplanned downtime.

Installation calls for a shaft free of burrs or wear marks and a housing that is clean and undistorted. Apply lubricant to the lip before pressing it in, and keep the seal square to the shaft rather than driving it in at an angle. If the shaft already shows a pronounced wear track, it may be worth reviewing the design. Speed, temperature and lubricant type all affect selection, so those details are worth having on hand before you request a quote.

If you are looking for an equivalent, provide code 5742 or the measured dimensions and describe the equipment. With that information we can check alternatives in the DBH line and other brands MR supplies, while keeping the mounting dimensions unchanged. We can also assist when the original seal is discontinued or the shaft has been reground.
