The DBH 5655 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 66.68 mm shaft diameter, 88.45 mm housing bore and 12.70 mm height make it suitable for equipment where axial space is limited. The Mz design indicates a configuration with a retaining lip and a dust lip, which improves protection against dust and dirt. It is used in gearboxes, pumps, electric motors and machinery in general. MR Accesorios Industriales sells it as part of its seal and radial shaft seal line.

The DBH 5655 is a radial shaft seal from the DBH brand, identified with code 5655. Its dimensions are 66.68 mm shaft diameter (d), 88.45 mm housing bore diameter (D) and 12.70 mm height (h). The Mz design corresponds to a configuration with a main retaining lip and a secondary lip or dust lip, which protects the sealing area from external particles. This type of seal is press-fitted into the housing and seals against the shaft by means of a flexible lip, generally made of elastomer, with a spring that ensures constant contact.

Typical applications of this seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the seal prevents oil or grease leaks and blocks the ingress of dust, water or chips. Its 66.68 mm shaft size is common in medium-sized equipment, and the Mz design is suitable for environments with dirt present, since the outer lip acts as an additional barrier.

To correctly select this seal, verify that the shaft and housing dimensions match those indicated: 66.68 mm and 88.45 mm respectively. The 12.70 mm height must match the housing depth. During installation, lubricate the lip with the same oil or grease used in the equipment, avoid damaging the sealing edge and make sure the shaft has no burrs or excessive wear. If the shaft has a groove or wear, consider using a wear sleeve or an alternative size.
