The DBH 8401/85 radial shaft seal is a lip seal that prevents oil or grease leakage and the entry of dust and water on rotating shafts. With dimensions of 18 mm shaft diameter, 32 mm housing bore and 7 mm height, and Lx design, it is press-fitted into crankcases, covers and gearboxes. It is a key part for maintaining lubrication and protecting bearings in industrial equipment.

This DBH 8401/85 oil seal has an 18 mm shaft diameter, a 32 mm housing bore and a 7.00 mm height. Its Lx design corresponds to a single lip seal with spring, without an external metal case, designed for press-fit housings. The sealing lip, generally made of elastomer, runs on the rotating shaft and retains the lubricant. DBH is an official brand that MR supplies, so the replacement part is available under its exact designation.

It is used in pumps, electric motors, gearboxes, compressors, mixers and transmission equipment. It also appears in automotive and agricultural machinery applications where shafts rotate inside an oil-filled crankcase. Its function is twofold: retain lubricant inward and block dust, water or particles outward. In environments with a lot of dirt or frequent washdowns, a seal in good condition extends bearing life and prevents downtime.

To select the seal correctly, verify that the shaft, housing and height dimensions match those of the housing and shaft. The Lx design requires a machined housing with adequate tolerance and a shaft with controlled hardness and roughness; if the shaft is scratched or worn, the lip will not seal properly. During installation, lubricate the lip with the same grease or oil used in service, insert it perpendicular and without striking the lip. Poor alignment or a worn spring cause premature leaks.
