The DBH 5285Pol is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It fits a 75 mm shaft, a 90 mm housing bore, and an 8 mm width. The Lx design pairs a main sealing lip with a dust lip on the same metal case, making it a practical choice where dust, chips, or washdown water are present. MR supplies this seal and can help you confirm the right fit for your application.

This seal belongs to the DBH line and carries the code 5285Pol. In the Lx configuration, the primary lip holds oil or grease inside the housing, while the secondary lip blocks external particles from reaching the sealing edge. That dual-lip layout is common on gearboxes, reducers, centrifugal pumps, conveyor rollers, and transmission shafts. It also suits food and process equipment that sees frequent cleaning, as well as road and agricultural machinery exposed to mud and dirt.

To select the correct seal, consider shaft speed, operating temperature, and the lubricant in use. The Lx design works well at moderate speeds and medium tightness demands. During installation, lubricate the lip with the same oil or grease used in the application, press the seal in perpendicular to the shaft, and avoid hitting it directly. If the shaft shows wear or grooves, a wear sleeve or a seal with a more flexible lip may be needed. Proper housing alignment is also critical to prevent early leaks.

When inquiring about a replacement or an equivalent to the 5285Pol, share the full code plus the shaft, housing, and width dimensions. A photo of the original seal helps speed things up. MR works with multiple brands and configurations, so the team can suggest an option that matches your service conditions.
