Its standard dimensions of 12 mm shaft diameter, 19 mm housing bore and 4.50 mm height make it suitable for compact spaces. It is used in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the designation 6905. Its dimensions are: shaft diameter (d) 12 mm, housing bore diameter (D) 19 mm and height (h) 4.50 mm. The Lt design indicates a single-lip configuration, suitable for applications where axial space is limited. The sealing lip, generally made of elastomer, runs on the rotating shaft to prevent oil or grease leaks and the ingress of dust or water. The outer metal case ensures a firm fit in the housing.

Typical applications for this seal include small electric motors, centrifugal pumps, speed reducers, fan shafts and power transmission equipment. It is also found in machine tools, packaging equipment and lubrication systems. Because of its compact size, it is common in mechanisms where radial and axial space is limited. In all cases, its function is to protect the bearings and extend the service life of the assembly, preventing lubricant loss and the entry of abrasive particles.

To correctly select a seal, take into account the shaft diameter, the housing bore diameter and the height. Check that the shaft surface is ground and has adequate hardness to prevent premature lip wear. The housing should have an entry chamfer so the seal is not damaged during installation. Peripheral speed and operating temperature determine the lip material. At MR Accesorios Industriales we can guide you on the most suitable configuration for your equipment.
