The DBH 8642 oil seal is a radial shaft seal with an 80 mm shaft diameter, a 105 mm housing diameter, and a 13 mm height. Its Lx design features both a sealing lip and a dust lip, which helps keep lubricant in and contaminants out in dusty or dirty conditions. This seal is commonly found in gearboxes, pumps, and bearing arrangements where reliable sealing is critical. MR Industrial Accessories supplies this brand and can assist you in selecting the correct seal for your application.

This radial shaft seal is identified by code 8642 and the DBH brand. The dimensions are shaft diameter (d) 80 mm, housing diameter (D) 105 mm, and height (h) 13.00 mm. The Lx designation means the seal has a primary sealing lip and a secondary dust lip, making it suitable for environments where dust or particles are present. As a brand we carry, DBH seals are available, and we can also suggest compatible alternatives.

Typical uses for this oil seal include gearboxes, centrifugal pumps, electric motors, bearings in agricultural and industrial machinery, and power transmission equipment. In these applications, the seal retains oil or grease to prevent leakage while blocking contaminants that could damage bearings or gears. It is a small but critical component for the service life of rotating equipment.

Proper installation is important for optimal performance. Ensure the shaft surface is polished, free of burrs, and has adequate hardness to minimize lip wear. The housing should be clean and undamaged. Lubricate the lip with the same lubricant being retained before installation. Verify that the spring is in place and that the seal is inserted perpendicular to the shaft. In dirty operating conditions, the Lx design with its dust lip helps extend service life.

If you need an equivalent oil seal, the most efficient approach is to provide the complete code from the part or drawing. With that information, we can cross-reference the exact size or recommend a compatible alternative. You can also supply the shaft, housing, and height measurements along with details about the application, and we will guide your selection. Feel free to inquire about other brands or configurations.
