The DBH 9857Pol is a radial shaft seal that keeps lubricant contained within a housing while blocking dust, water and other contaminants from reaching the shaft. Its dimensions are shaft 35 mm, housing 56 mm and height 10 mm, and it uses the Lz-R AH design. This seal is a common replacement item in industrial machinery, and MR Industrial Accessories can help you confirm the correct part for your equipment.

This seal carries the designation 9857Pol within the DBH line. The three key measurements are: shaft diameter (d) 35 mm, housing diameter (D) 56 mm and height (h) 10.00 mm. The Lz-R AH design combines a main sealing lip with a secondary dust lip, making it suitable for environments where moderate contamination is present. An internal spring maintains steady pressure on the elastomer lip against the shaft.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission assemblies. In each case, it serves to hold oil or grease inside the unit and to shield bearings and gears from dirt. Because it is a wear component, it should be replaced when leakage appears or when unusual noise develops around the sealing area.

Proper installation starts with checking the shaft for burrs or splines that could cut the lip. Apply a compatible grease to the lip before sliding it into place, and use a driver that contacts only the outer diameter, never the lip itself. The shaft must have adequate hardness and surface finish; if it shows wear, a repair sleeve may be needed. The housing bore should be clean and undistorted.

If you need a cross-reference to another brand, provide the part number 9857Pol or the dimensions 35 x 56 x 10 mm along with the design type. MR Industrial Accessories compares these details against manufacturer data to suggest a compatible alternative. We can also tell you whether a different height variant will fit your mounting space or whether the Lz-R AH design is required for your application.
