This item is a DBH radial shaft seal, identified by the designation 8258. Its dimensions are 28 mm shaft diameter (d), 40 mm housing diameter (D) and 8.00 mm height (h). The Lr design corresponds to a configuration with a retaining lip and elastomer body, suitable for rotating shafts with lubrication. It is a standard replacement part for press fitting into cylindrical housings.

It is used in gearboxes, pumps, electric motors, compressors and power transmission equipment. Its main function is to prevent oil or grease leaks and block the entry of dust, water or particles. It is commonly found in applications where the shaft rotates at moderate speeds and the operating temperature is typical of industrial equipment.

To select correctly, verify that the shaft and housing diameters match the dimensions indicated. The shaft surface must be ground and free of burrs; the housing must be clean and have a suitable entry chamfer. During assembly, lubricate the lip and use a support tube to avoid damaging it. If the previous oil seal failed, check the condition of the shaft and housing before replacing it.
