The DBH 8683Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent dust, water or contaminating particles from entering. With dimensions of 12.50 mm shaft, 20.00 mm housing and 5.00 mm height, and an Lz-Bidi design, it fits applications requiring sealing in both directions of rotation or pressure. It is a common replacement part in industrial equipment and agricultural machinery.

This item is a radial shaft seal from the DBH brand, identified with the part number 8683Pol. Its standardized dimensions are 12.50 mm for the shaft diameter, 20.00 mm for the housing diameter and 5.00 mm height. The Lz-Bidi design indicates that the sealing lip is prepared to work with sealing in both directions, making it suitable for shafts that rotate in both directions or where pressure can reverse. The 8683Pol designation allows it to be quickly located in catalogs and replenishment systems.

Typical applications for a seal of this size include small gearboxes, electric motors, pumps, compressors, drive shafts and power transmission equipment in general. It is also used in agricultural machinery, material handling equipment and production lines where bearings and gears need protection from external contamination and oil or grease leaks must be prevented. Its compact size makes it common in assemblies where radial space is limited.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. In addition, it is important to consider the rotation speed, the working temperature and the type of lubricant. The Lz-Bidi design of this seal offers a double lip or lip with additional protection, which improves sealing in dusty or dirty environments. During assembly, it is recommended to lubricate the lip, use a suitable installation tool and avoid striking the seal to prevent damaging the sealing edge.
