The DBH 8729 radial shaft seal is a lip seal designed for rotating shafts of 15.90 mm diameter, with a 30 mm housing and 6 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate the wear of bearings and bushings. It is press-fitted into the housing and runs on the shaft surface, forming a reliable dynamic barrier in industrial equipment.

This item is a radial shaft seal from the DBH line, identified with the part number 8729. Its nominal dimensions are: shaft diameter 15.90 mm, housing diameter 30 mm and height 6.00 mm. The Mx design corresponds to a configuration with a single lip and spring, suitable for rotating shafts with permanent lubrication. The elastomeric lip guarantees sealing in both directions and tolerates small misalignments.

It is used in gearboxes, pumps, electric motors, mixers and transmission equipment where oil or grease must be confined. It also appears in machine tools, conveyors and low-pressure hydraulic systems. It is commonly found in applications where the shaft rotates continuously and bearings need to be protected from external contamination.

To select the correct oil seal, verify that the shaft diameter, housing and height match the values on the product page. The shaft surface must be ground and free of marks; the housing, clean and free of burrs. During assembly, lubricate the lip and use an insertion tool so as not to damage it. Avoid striking the seal with pointed tools.
