The DBH 8369/85 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent contaminants from entering on rotating shafts. Its designation indicates the main dimensions: 22 mm shaft diameter, 31.95 mm housing and a height of 3.00/6.50 mm. It is used in gearboxes, pumps, electric motors and power transmission equipment where axial space is limited and a reliable closure is needed.

This item is a radial shaft seal from the DBH brand, identified with the code 8369/85. Its nominal dimensions are 22 mm shaft diameter (d), 31.95 mm housing diameter (D) and a height (h) of 3.00/6.50 mm. The A 323 design corresponds to a single-lip configuration with a spring, suitable for rotating shafts. The stepped height of 3.00/6.50 mm allows it to be seated in cavities with a shoulder, keeping the lip in uniform contact with the shaft.

Typical applications of this seal include gearboxes, centrifugal pumps, low-power electric motors, spindles and power transmission equipment. In all cases, its function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings and gears. It is a critical part in preventive maintenance, since timely replacement prevents leaks and premature wear.

To install this seal correctly, verify that the shaft has the proper hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil used in the equipment before inserting it and use an installation tube that presses on the outer diameter, never on the lip. The 3.00/6.50 mm height requires a housing with a shoulder that matches that geometry. If the shaft shows wear, consider a design with an auxiliary lip.
