The DBH 5757 is a radial shaft seal designed to keep lubricant in and contaminants out on rotating shafts. It fits a shaft of 19 mm, a housing bore of 31.73 mm, and has a height of 9.52 mm. The Mz design defines its lip and metal case geometry. MR supplies this seal for maintenance and replacement in industrial equipment.

This seal belongs to the DBH line and is identified by the code 5757. The key dimensions are: shaft diameter 19 mm, housing diameter 31.73 mm, and height 9.52 mm. The Mz designation refers to the specific lip and case configuration, which is engineered to retain lubricant and exclude dust or moisture.

Typical applications include gearboxes, pumps, electric motors, compressors, and other machinery where a rotating shaft passes through a housing. The flexible lip rides on the shaft while the outer case is press-fitted into the bore. This creates a barrier that protects bearings and gears from contamination and oil loss.

For proper selection, verify that the shaft diameter, housing diameter, and height match the original seal. Also confirm that the Mz design is suitable for your operating conditions. Inspect the shaft surface before installation; scratches or wear can compromise sealing. During installation, lubricate the lip, align the seal squarely, and press it in using a tool that contacts only the outer case.
