The DBH 8400Pol is a radial shaft seal, also called an oil seal, sized for a 20 mm shaft, a 32 mm housing bore and a 6 mm height. It keeps lubricant where it belongs and blocks dust, water and particles from reaching bearings and bushings. You will find this size in gearboxes, pumps and small electric motors. MR Industrial Accessories offers it within its seals and oil seals range.

This seal follows the Lx-H construction, a radial shaft seal variant made for tight axial spaces. The lip rides on the rotating shaft, while the outer diameter presses into the housing. The size code reads as shaft 20 mm, housing 32 mm, width 6.00 mm. Because tolerances matter, confirm these three measurements against your equipment before ordering.

A 20 x 32 x 6 mm seal shows up in small gearboxes, centrifugal pumps, low-power motors, spindles and transmission components. In each case it shields nearby bearings or bushings from outside contamination and holds the lubricant film in place. Machine tools, packaging lines and irrigation systems also use this size, especially where dust or moisture would otherwise shorten the life of rotating parts.

When choosing a replacement, check shaft diameter, housing bore and the space available for height. Also consider rotation speed, operating temperature and the lubricant in use, since these affect the lip compound and spring selection. At installation, apply lubricant to the lip, keep the seal square, avoid hammer blows and inspect the shaft for burrs or scratches. Handling it carefully helps prevent early leaks.
