The DBH 8857 radial shaft seal is a lip seal designed for 5 mm shafts, with a 15 mm housing and 4 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings, bushings or gears. It is press-fitted into the housing and runs on the rotating shaft, forming a reliable dynamic barrier in small-sized equipment.

This item is a radial shaft seal from the DBH line, identified with the code 8857. According to the product page data, it corresponds to a 5 mm diameter shaft, a 15 mm housing and a total height of 4.00 mm. The Lx design indicates a single-lip configuration with spring, suitable for oil or grease retention in applications where axial space is limited. It is a precision part that is installed with interference in the housing and seals against the shaft surface.

It is used in small electric motors, gearboxes, low-power pumps, pneumatic tools, household appliances and instrumentation equipment. It also appears in light transmission boxes, fans, small compressors and laboratory machinery. In all cases it serves the dual function of containing lubricant and preventing external contamination, extending bearing service life and reducing corrective maintenance.

To select the correct seal, verify that the shaft diameter, housing diameter and height match the values on the product page. The shaft surface must be ground and free of burrs; the housing must be clean and have the proper entry chamfer. During installation, lubricate the lip and use a support tube to avoid damaging it. If the equipment operates at high speed or extreme temperatures, consult us about material variants.
