For rotating equipment, the DBH 5643 radial shaft seal keeps lubricant in and contaminants out. Its size—50 mm shaft, 68 mm housing, 14 mm height—suits medium-duty applications like pumps, motors, and gearboxes. At MR Industrial Accessories, we help you select the right seal for your machinery.
The DBH 5643 follows the Mz design, a manufacturer's configuration that pairs a sealing lip with a metal case and an additional exclusion lip. The part number itself indicates the dimensions: 50 mm shaft, 68 mm housing, 14 mm height. This seal retains oil or grease on rotating shafts while blocking dust and moisture from entering.
You'll find this seal in equipment where a shaft turns inside a stationary housing: centrifugal pumps, electric motors, gearboxes, mixers, fans, and belt or chain drives. It also appears in agricultural and industrial machines exposed to dust or water. In these settings, the seal safeguards bearings and stops lubricant loss.
During installation, verify the shaft is free of burrs or wear and the housing is clean and undented. Apply the same oil or grease used in the equipment to the lip, then press the seal in with a flat driver to avoid distortion. If the shaft has a visible groove, consider a seal with the lip positioned differently or shaft replacement. Speed, temperature, and lubricant type all influence seal selection.
Need a cross-reference from another brand? Send code 5643 plus the shaft, housing, and height dimensions, and tell us the equipment type. We'll search for an alternative in the same radial shaft seal category. If you lack dimensions, we can guide you on measuring them directly from the machine.
