The DBH 5261Sil oil seal is a single-lip radial seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Due to its dimensions of 25.40 mm shaft, 38.07 mm housing and 6.35 mm height, and its Lz design, it is a common replacement part in gearboxes, pumps and low- and medium-demand transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you can choose the correct seal.

This item is a DBH radial shaft seal of the designation 5261Sil, with the following dimensions taken from the product page: shaft diameter 25.40 mm, housing diameter 38.07 mm and height 6.35 mm. The Lz design corresponds to a sealing lip with spring and metal body, intended for rotating shafts with permanent lubrication. The lip elastomer works on the shaft race and the outer case fits by interference in the housing. It is a wear part: when oil loss or dirt ingress appears, it is replaced.

Typical applications for a seal of this size include gearboxes, gearmotors, centrifugal pumps, compressors, fan shafts and belt or chain transmission equipment. It is also used in machine tools, conveyors and process equipment where the lubricant must be separated from the environment. As it is an inch size converted to millimeters, it is common in imported equipment and in machinery replacement with shafts standardized in the inch system.

To select and assemble the seal, take into account the condition of the shaft race: if there is wear, scratches or corrosion, the lip will not seal even if the size is correct. Also verify the concentricity and finish of the housing, and lubricate the lip before inserting it so as not to damage it. The seal is mounted with the lip facing the lubricant side and is seated with a tube of suitable diameter, never striking the elastomer. If the equipment works with high vibration or temperature, evaluate a more resistant compound.
