For rotating shafts that need a dependable barrier between lubricant and the outside environment, the DBH 5739 radial shaft seal is a direct-fit option. Its Lz configuration combines a sealing lip with a spring, and the elastomer body stands up to oils and greases. The three key measurements to match against your equipment are shaft 87.31 mm, housing 107.93 mm and width 15.87 mm.

Reading the size callout is the first step in any seal replacement. The 87.31 mm figure is the shaft diameter the lip rides on, 107.93 mm is the bore it presses into, and 15.87 mm is the overall width. Once those three values line up with the housing and shaft in front of you, the Lz design tells you the seal has a spring-loaded lip built for continuous rotation in a cylindrical seat.

Typical installations include gearboxes, centrifugal pumps, electric motors, compressors, spindles and power transmission assemblies. Plants in food processing, chemical, petrochemical and general process work rely on this style of seal because keeping lubricant in and keeping particles and moisture out is what protects bearings and gears from early failure.

Good results start with the shaft itself. A ground surface with suitable hardness limits lip wear, and the Lz design suits moderate peripheral speeds and low pressure duty. Set the lip with a film of lubricant and press it in with a proper installation tool so the sealing edge is not nicked or rolled during fitting.

If your shaft and bore measurements point to a different size, that is workable. Send part number 5739 or simply your shaft and housing dimensions, and the team can review the seals and oil seals line for a matching alternative or locate the size you need.
