The DBH 9031 radial shaft seal is a lip seal that mounts on the shaft and blocks the passage of lubricant, dust and water in rotating equipment. Its dimensions of 10 mm shaft, 20 mm housing and 6 mm height place it in the range of compact seals for light mechanisms. MR Accesorios Industriales supplies this DBH reference and quotes it on WhatsApp on request.

The DBH 9031 is a seal with Lx design, featuring a sealing lip and metal body. Its dimensions are 10 mm shaft diameter (d), 20 mm housing diameter (D) and 6.00 mm height (h). The Lx design indicates a single-lip configuration with spring, intended to retain lubricant and exclude contaminants on rotating shafts. It is press-fitted into the housing and runs on the shaft surface, which must be ground and free of marks so the lip seals evenly.

Due to its size, this seal is used in low and medium power equipment: small electric motors, centrifugal pumps, light gearboxes, fans, machine tools and auxiliary drives. It also appears in applications where radial space is limited and a reliable closure is needed without adding volume. It is a wear part: when the lip hardens, crystallizes or loses elasticity, it starts losing oil and should be replaced before the shaft or housing is damaged.

To select the correct seal, verify that the shaft and housing diameters match the values on the product page. The 6.00 mm height must fit into the cavity without sitting proud. Check the shaft condition: if it has wear or a marked groove, the new lip will not seal properly. During installation, lubricate the lip with the same oil as the equipment, insert it perpendicular to the shaft and tap on the outer ring, never on the lip. If the seal operates at high peripheral speed or temperature, ask us about the lip compound.

To quote the DBH 9031, send us the part number, the shaft, housing and height dimensions, and a photo of the old seal. With that data we look for the equivalent in the same brand or in another line we carry. We also tell you whether the Lx design is suitable for your application or if another lip type is better. The idea is that you are not stopped by a seal you cannot source.

MR Accesorios Industriales supplies seals and oil seals from various brands. If you need a quote for the DBH 9031 or a replacement, send the part number on WhatsApp and we will reply with the alternative. You can also ask about other seals in the same category or installation tools to fit it without damaging the lip.
