The DBH 5655 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 66.68 mm shaft, a 88.45 mm housing bore and a 12.70 mm height, and its Mz design includes a retaining lip plus a dust lip. This makes it a practical choice for gearboxes, pumps, motors and similar machinery where dirt is present and axial space is tight.

The seal carries the DBH brand and the code 5655. In the Mz design, a main lip seals against the shaft and a secondary dust lip adds a barrier against external particles. The seal is pressed into the housing, and a spring keeps the elastomer lip in constant contact with the shaft.

Common installations include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In these positions, the seal prevents oil or grease from escaping and blocks dust, water and chips from entering. The 66.68 mm shaft size appears in medium-sized equipment, and the Mz layout suits areas where dirt is a concern.

When selecting a replacement, confirm the shaft and housing dimensions: shaft 66.68 mm, housing 88.45 mm, width 12.70 mm. The height must match the housing depth. During installation, lubricate the lip with the same oil or grease used in the equipment, protect the sealing edge from damage, and check the shaft for burrs or wear. If the shaft is grooved, a wear sleeve or an alternative size may be needed.
