The DBH 6654 radial shaft seal is a lip seal that mounts on the shaft and inside the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions are 25.00 mm shaft, 40.00 mm housing and 7.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment that rotate at moderate speed and need a reliable barrier between the inside and the outside.

This item is a seal from the DBH line, identified with part number 6654. Its nominal dimensions are 25.00 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height. The Lx design corresponds to a single-lip radial shaft seal with spring, intended for rotating shafts with permanent lubrication. The elastomeric lip bears on the shaft and the metal case fits into the housing to maintain sealing during rotation.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive equipment. In all cases it serves to retain the oil or grease inside the assembly and prevent contaminants from entering from the outside. It is a wear part that should be checked when lubricant leaks or abnormal noises appear in the seal area.

For installation, verify that the shaft is clean, free of burrs and deep marks, and that the housing has the correct diameter and depth. Lubricate the lip before inserting it and seat the seal with a tube or press that bears on the case, never on the lip. If the shaft shows wear, consider a seal with the lip in a different position. Selection depends on the speed, temperature and type of lubricant in the equipment.
