The DBH 8770Vit radial shaft seal is a lip seal that mounts on the shaft and inside the housing to contain lubricant and block the entry of dust, water or particles. Its Lx-Bidi design combines a main sealing lip with a bidirectional configuration that improves retention in both directions of rotation. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with 140 mm shafts.

This DBH 8770Vit seal has a shaft diameter of 140 mm, a housing diameter of 170 mm and a height of 15.00 mm. The Lx-Bidi design indicates a construction with a sealing lip and bidirectional geometry, intended for applications where the shaft can rotate in both directions or where there are direction reversals. The lip elastomer works on the shaft surface, while the outer diameter maintains the fit in the housing.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, large electric motors and belt or chain transmission equipment. In all cases it performs the function of retaining oil or grease and preventing external contamination. It is also used in road machinery, mining equipment and process lines where the 140 mm shaft is common.

To correctly select this seal, verify that the shaft diameter, housing diameter and height match the values on the product page. The Lx-Bidi design requires respecting the mounting direction indicated by the manufacturer and ensuring the lip is not damaged during installation. The shaft surface must be ground and lubricated before sliding the seal on. If the equipment operates with high vibration or temperature, consider an alternative elastomer.
