The DBH 9975 radial shaft seal is a lip seal designed to block the passage of oil, grease or contaminants on rotating shafts. With dimensions of 21 mm shaft, 41.30 mm housing and 4.00 mm height, and an A 360 design, it is press-fitted into the housing and runs against the shaft. It is a key part in gearboxes, pumps, electric motors and power transmission equipment, where it prevents leaks and protects bearings from dust and moisture.

This item is a radial shaft seal from the DBH brand, identified by code 9975. Its dimensions are 21 mm shaft diameter, 41.30 mm housing diameter and 4.00 mm height. The A 360 design indicates a specific construction configuration within the DBH seal line. The sealing lip, made from elastomers resistant to oils and greases, ensures tightness under continuous rotation. The outer metal case ensures a firm fit in the housing and facilitates press fitting.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors, drive shafts and industrial equipment in general. It is used to retain lubricant and prevent the entry of foreign particles that accelerate wear on bearings and bushings. Due to its compact size, it is common in equipment where radial space is limited and efficient sealing is required at moderate speeds. It is also found in agricultural, textile and process machinery.

To correctly select this seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The shaft surface must be ground and free of burrs; a fine surface finish is recommended to extend lip life. During assembly, lubricate the lip with the same oil or grease used in the equipment and press perpendicularly to avoid damaging it. If the shaft shows wear, evaluate the possibility of using a wear sleeve or an alternative size.
