The DBH 8357 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It measures 20.50 mm at the shaft, 41.20 mm at the housing and 5.00 mm in height, and uses an Mx design. MR Industrial Accessories supplies this brand for gearboxes, pumps and motors.

The Mx designation tells you this seal has a sealing lip backed by a spring, so the lip stays in contact with the shaft as it turns. The elastomer compound resists oils and greases, while the metal case holds its shape under operating conditions. These elements make the DBH 8357 a precision component for sealing duty in tough environments.

You will find seals like this in gearboxes, centrifugal pumps, electric motors, conveyor rollers and transmission systems. They also show up in agricultural machinery, construction equipment and production lines. The job is always the same: stop lubricant from escaping and keep dust or water from reaching bearings and gears, which helps the assembly last longer and cuts unplanned downtime.

When selecting a replacement, match the three dimensions to the application: shaft 20.50 mm, housing 41.20 mm, width 5.00 mm. Check that the shaft surface is free of burrs and heavy wear, and that the housing bore has a proper chamfer so the lip is not damaged during installation. Lubricate the lip before pressing the seal in and keep it perpendicular to the shaft.
