The DBH 5112 radial shaft seal is a lip seal that keeps lubricant contained and contaminants out of rotating shafts. It measures 25.40 mm at the shaft, 44.50 mm at the housing bore and 5.00 mm in height. The Lz design denotes a spring-loaded sealing lip for moderate speeds and demanding conditions. MR Industrial Accessories LLC supplies this brand to customers across the United States and in several Latin American countries.

This radial shaft seal is identified by part number 5112 and belongs to the DBH brand. Its dimensions are shaft 25.40 mm, housing 44.50 mm, width 5.00 mm. The Lz designation indicates a spring-loaded lip, intended for rotating shafts where low friction and good wear resistance are needed. The lip elastomer is bonded to the metal body to handle moderate pressure and typical industrial temperatures.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. Its role is to hold oil or grease inside the assembly and block dust, water or particles from entering. Because a failed seal can lead to lubricant loss and premature damage to bearings and gears, it is a critical item in any maintenance program.

Proper installation starts with checking shaft hardness and surface roughness, ensuring there are no burrs or marks that could harm the lip. Lubricate the lip with the same oil used in the equipment and verify that the housing is clean and free of deformation. When selecting a seal, consider shaft surface speed, operating temperature and the chemical compatibility of the elastomer with the fluid being retained.
