The DBH 8490Pol is a single-lip radial shaft seal designed to keep lubricant in and contaminants out of rotating equipment. With a 40.00 mm shaft, 58.00 mm housing and 11.30 mm height, it fits common transmission and pump applications where axial space is tight. MR Industrial Accessories supplies this seal as part of its seals and oil seals range.

This seal carries the DBH designation 8490Pol and the A 075 design, which defines the lip and outer body geometry. The dimensions are: shaft 40.00 mm, housing 58.00 mm, height 11.30 mm. As a single-lip seal, it is intended for rotating shafts with lubrication, helping retain oil or grease and block dust, water or particles from entering the assembly.

You will find seals of this size in gearboxes, pumps, electric motors, rollers and power transmission equipment. They also appear in agricultural machinery, conveyors and other industrial setups where a shaft turns inside a housing and a dependable sealing barrier is required. The 40 x 58 x 11.30 mm size matches a nominal 40 mm shaft with a standard housing, which simplifies replacement on installed equipment.

During installation, make sure the shaft and housing are clean and free of burrs or marks that could harm the lip. Apply the same oil or grease used in the equipment to the lip before fitting, and press the seal by its outer body with a tube or spacer, never on the lip. The 11.30 mm height must align with the housing depth so the seal seats completely. If the shaft shows wear, an auxiliary lip version may be worth considering.

To find an equivalent, send the part number 8490Pol or the dimensions of the seal you are replacing: shaft diameter, housing diameter and height. With that information we can search for an alternative in the DBH line or other brands we carry. Telling us the equipment and working temperature also helps us refine the lip material recommendation.
