The DBH 9815 is a radial shaft seal designed to retain lubricant and block dust, water, and particles where a rotating shaft meets its housing. Its compact size makes it suitable for small gearboxes, electric motors, pumps, and transmission equipment with limited axial space. MR Industrial Accessories LLC supplies this brand and can help you select the right seal based on shaft, housing, and operating conditions.

This oil seal has design Mx and the following dimensions: shaft 20 mm, housing 31.75 mm, width 6.00 mm. The sealing lip runs against the shaft while the outer case presses into the housing. The code 9815 identifies the size within the DBH catalog. Before installation, confirm that the shaft and housing match these values, as even a small difference can prevent proper sealing or cause leaks.

Typical uses for a seal of this size include small electric motors, gearboxes, centrifugal pumps, compressors, machine tools, and belt or chain transmission equipment. In each case, it keeps oil or grease in and contaminants out. It also acts as a barrier in gearboxes and mechanisms where the shaft rotates at moderate speeds and temperatures stay within the material's usual limits.

When selecting a seal, consider shaft speed, working temperature, and lubricant type. Design Mx is a single lip with spring, suited to rotating shafts with little misalignment. During installation, lubricate the lip, check that the shaft is free of burrs or marks, and press the seal perpendicular to the shaft. If the housing is damaged or the shaft is worn, sealing may fail even if the size is correct.

If you need an equivalent, send code 9815 along with the shaft, housing, and width dimensions. A photo of the old seal or the assembly drawing also helps. Our team compares this data with available options and proposes the best alternative, including a seal from another series or brand that performs the same function.
