The DBH 6921 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering equipment with a rotating shaft. Due to its dimensions — 108.05 mm shaft, 142.88 mm housing and 13.00 mm height — it is used in gearboxes, pumps and medium-to-large power transmissions. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal for your application.

This item is a DBH 6921 radial shaft seal with the following dimensions: shaft diameter 108.05 mm, housing diameter 142.88 mm and height 13.00 mm. The Kz design corresponds to a configuration with a sealing lip and metal reinforcement, suitable for retaining oil or grease on rotating shafts. The 6921 designation identifies the exact size within the DBH line. Before mounting, check that the housing and shaft match these dimensions, since even a minimal difference can cause leaks or premature wear.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, mixers and power transmission equipment. In these systems, the seal prevents lubricant loss and protects the bearings from dust, water or particles. It is also used in agricultural and industrial machinery where the shaft rotates at moderate speeds and oil is present. If your equipment operates at high temperatures or high peripheral speeds, contact us to evaluate the lip material.

To select and mount it correctly, take into account the rotation speed, service temperature and type of lubricant. The Kz design is usually mounted with the lip facing the fluid to be retained. Lubricate the lip before inserting it and use a mounting tool to avoid damaging it. Check that the housing has no burrs and that the shaft shows no wear. If the previous seal failed, check the alignment and bearing clearance. These practices extend the service life of the seal.
