A rotating shaft needs a seal that holds lubricant in place and keeps dust, water and other contaminants out. The DBH 9031Pol is a radial shaft seal built for that job, sized for a 10 mm shaft, a 20 mm housing bore and a 6 mm height. Its Lx design points to a sealing lip with a spring, the usual setup for dynamic sealing on rotating equipment. MR Industrial Accessories supplies this brand within its seals and oil seals range, and quotes are handled by part number through WhatsApp or email.

Reading the reference helps when you are matching a replacement. The part number is 9031Pol, under the DBH brand. The three figures that matter for fit are shaft 10 mm, housing bore 20 mm and height 6 mm. In the Lx designation, the lip carries a spring; the x typically signals a variation in profile or material, so the manufacturer's data sheet is the right place to confirm the exact compound and temperature limits. Nitrile rubber (NBR) is the standard material, which handles mineral oils and greases well.

These seals turn up in small centrifugal pumps, low-power electric motors, speed reducers, gearboxes and power transmission equipment, as well as in agricultural machinery, material handling equipment and hydraulic systems. Where axial room is tight, the compact 10x20x6 mm envelope often makes this the practical choice for containing lubricant and blocking dust or water ingress.

Before fitting, check that the shaft and housing match the stated diameters. A smooth, burr-free shaft with adequate hardness helps the lip last. Lubricating the lip before pressing it in and using a proper installation tool reduces the risk of damage. When selecting, weigh rotation speed, operating temperature and the fluid being retained against the elastomer's chemical compatibility.

If you need an equivalent, send the part number 9031Pol or the dimensions 10x20x6 mm and the team will look across available seals and oil seals in different brands and configurations. Variations in lip design, material and spring type can be reviewed with you so the choice suits the application. MR Industrial Accessories also manufactures split plummer block housings, roller chains and sheaves, and serves customers throughout the United States and in several Latin American countries.
