MR Industrial Accessories supplies this brand as part of its seals and oil seals line.

This seal belongs to the DBH line and carries the code 9491/85. Its key dimensions are shaft 23 mm, housing 38 mm, and height 6.50/7.00 mm. The A 219 profile means a sealing lip with a metal spring that holds lubricant in and keeps contaminants out. The two height values give some flexibility in the housing bore without compromising the fit. It is a common replacement item in industrial maintenance.

You will find this oil seal in centrifugal pumps, electric motors, gearboxes, compressors, and transmission equipment. It is typically installed at shaft outputs where continuous lubrication is present and leaks must be avoided. Machine tools, process equipment, and conveyor systems also use it. Due to its compact size, it appears in low and medium power equipment running at moderate speeds. The lip and spring material should be selected based on the fluid and operating temperature.

When installing a seal like the 9491/85, verify that the shaft is free of burrs and wear and that the housing is clean and undistorted. Lubricate the lip before insertion and avoid hitting it during installation. Shaft-to-housing concentricity is critical so the lip does not bear unevenly. If the shaft has a deep groove, consider a wear sleeve or a different size. Allowable pressure and speed depend on the lip compound and spring, which should be confirmed against the manufacturer's product page.

For an equivalent, send the code 9491/85 along with the shaft and housing dimensions. A photo of the old part or the assembly drawing also helps. With that information, we at MR Industrial Accessories find the best match for your equipment, whether from the same brand or another line we carry. You do not need the exact number: dimensions and service conditions are enough to start the search.
