The DBH 6811 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 40.5 mm shaft diameter, 56 mm housing diameter and 7 mm height, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a wear part that should be replaced at the first sign of leakage.

This item is a DBH 6811 radial shaft seal, identified by the designation 6811. Its dimensions are 40.5 mm shaft diameter (d), 56 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a seal with a sealing lip and spring, suitable for rotating shafts with lubrication. DBH is an official brand that MR carries, so the product conforms to the manufacturer's data sheet.

Typical applications for this seal include gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. It is used to confine oil or grease in bearings and gears, and to protect them from external contamination. It is commonly found in equipment where the shaft rotates at moderate speeds and there is exposure to dust or moisture. It is also used as a replacement part in preventive machinery maintenance.

For installation, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the seal lip with the same oil or grease used in the equipment before inserting it. Place the seal perpendicular to the shaft and press evenly until it seats at the bottom of the housing. Avoid striking the lip. If the shaft shows wear, consider a neighboring size or a seal with an additional lip. Selection depends on speed, temperature and type of lubricant.
