The DBH 6303 is a radial shaft seal with Lz design, featuring a sealing lip and metal case. Its dimensions are 30.10 mm shaft diameter (d), 48.97 mm housing diameter (D) and 11.11 mm height (h). The Lz design indicates a single-lip configuration with spring, suitable for lubricated rotating shafts. It is press-fitted into the housing and seals against the shaft, retaining lubricant and blocking the ingress of dust, water or particles.

This type of oil seal is used in gearboxes, pumps, electric motors, transmission shafts and process equipment. It is common in the food, chemical and manufacturing industries, where contamination or oil loss affects performance. It is also found in machine tools, conveyors and hydraulic systems. Its function is to protect bearings and gears, extending the service life of the assembly and reducing maintenance downtime.

To select the correct oil seal, verify the shaft diameter, housing diameter and height. The shaft surface must be clean, free of burrs and scratches, and with adequate hardness to prevent premature wear. The housing must have the entry chamfer to avoid damaging the lip during installation. Lubricate the lip with the same oil as the equipment before installing. If the shaft shows wear, consider a repair sleeve or an alternative size.
