The DBH 8123 radial shaft seal is a lip seal designed for large-diameter shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that could damage bearings and gears. With dimensions of 340 mm shaft, 380 mm housing and 12 mm height, and an Lz design, this seal is used in equipment where reliable sealing is critical for production continuity.

This item is a DBH radial shaft seal, identified by code 8123. Its dimensions are 340 mm shaft diameter (d), 380 mm housing diameter (D) and 12.00 mm height (h). The Lz design corresponds to a configuration with a sealing lip and a specific profile that allows it to adapt to mounting conditions. It is manufactured with materials resistant to wear and to the oils and greases commonly used in industry. It is a replacement part for equipment operating with large shafts.

Typical applications of this seal include gearboxes, mills, mixers, high-flow centrifugal pumps, conveyors and heavy machinery in general. In all these machines, the DBH 8123 seal serves to confine lubricant and protect bearings or bushings from external contamination. It is commonly found in industries such as cement, mining, steel, paper and food, where large-diameter shafts and demanding conditions require robust, long-lasting seals.

To correctly select this seal, verify that the shaft and housing dimensions match those indicated: 340 mm and 380 mm respectively, with a height of 12.00 mm. The Lz design must be compatible with the type of mounting and the direction of rotation. During installation, make sure the shaft has no burrs or marks that could damage the lip, lubricate the lip with the same oil or grease used in the equipment and place the seal perpendicular to the shaft. Avoid striking it directly; use a suitable tube or press.
