The DBH 1333 is a radial lip seal built to keep lubricants in and contaminants out of rotating assemblies. Its 47 mm housing diameter and 10.00 mm height suit common industrial housings, and the A 378 design provides a defined sealing profile for shaft applications. MR Industrial Accessories supplies this seal to maintenance and purchasing teams across the United States and Latin America.

Reading the code helps when you are matching a replacement. The DBH 1333 designation points to a specific lip geometry identified as A 378. The dimensional callout lists 0 mm for the shaft diameter (d), 47 mm for the housing bore (D), and 10.00 mm for the height (h). The seal is made from high-resistance elastomers, with a lip that maintains contact under rotation.

You will find this type of seal in gearboxes, pumps, electric motors, transmission shafts, and general industrial equipment. Its job is to hold oil or grease in place while blocking dust, water, and particles from reaching bearings and shafts. Agricultural machinery, production lines, and continuous-process equipment are common locations.

Installation starts with clean, burr-free surfaces on both the housing and the shaft. Lubricate the lip before pressing the seal into position, and confirm that the 10.00 mm height fits the housing depth. When selecting a seal, consider rotation speed, operating temperature, and the fluid being retained. If any of these details are unclear, send your equipment data and we can review it with you.

If you are looking for an equivalent, share the code 1333 or the three dimensions of your current seal—shaft diameter, housing, and height—and we can suggest alternatives. Quotes are handled by WhatsApp or email using the part number, and our team responds promptly with technical guidance to help you choose the right part.
