The DBH 5431 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its Lz design adds a dust lip to the sealing lip, so it works as a double barrier in tight spaces. MR Industrial Accessories supplies this part number and can help you confirm it fits your application.

The designation 5431 tells you the size: shaft 11.11 mm, housing 25.37 mm, width 9.52 mm. The Lz configuration means the seal has both a sealing lip and a dust lip, which is useful when dust or water is present. An internal spring keeps the elastomer lip in uniform contact with the shaft.

You will find this type of seal in gearboxes, pumps, electric motors, compressors and other power transmission equipment. It prevents oil or grease from escaping and blocks particles, water or dust from entering. Common settings include agricultural machinery, process equipment and hydraulic systems with moderate shaft speeds.

Before installing, check that the shaft, housing and width dimensions match the seal. The shaft should be ground and have the right hardness; the housing must be clean and free of burrs. Lubricate the lip and use a proper installation tool to avoid damage. Concentricity and parallelism matter for a good seal and long service.
