The DBH 1271 oil seal is a single-lip radial shaft seal mounted on rotating shafts to retain lubricant and block the entry of dust, water or particles. Its A 419 design and dimensions of 25 mm shaft, 47 mm housing and 11.00/12.50 mm height make it a common replacement part in gearboxes, pumps and electric motors. At MR Accesorios Industriales we sell it as part of our line of seals and oil seals for industrial maintenance.

This oil seal is identified by code 1271 and belongs to the radial shaft seal category. Its dimensions are shaft (d) 25 mm, housing (D) 47 mm and height (h) 11.00/12.50 mm, with an A 419 design. That dual height allows it to be fitted in cavities with different seat depths without modifying the housing. The sealing lip runs on the shaft and the outer case holds the part firmly in its seat. It is a wear part: it is replaced when lubricant leakage or contaminant ingress appears.

Typical applications are gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where a rotating shaft exits a lubricated housing. It is also used in machine tools, mixers and conveyors. In all cases it performs two functions: retaining the oil or grease inside the assembly and preventing dust, chips or water from entering from the outside. That is why it is commonly found in preventive maintenance at plants and factories.

To select the correct oil seal, check the shaft diameter, the housing diameter and the available depth. The size 25 x 47 x 11.00/12.50 mm must match those three dimensions. Also check the condition of the running surface: a scratched or worn shaft means the lip will not seal even if the size is correct. During installation, lubricate the lip, avoid striking it and make sure it enters perpendicular to the housing. If the shaft has burrs, remove them before fitting the part.

If you need an equivalent or a nearby size, send us code 1271 together with the shaft, housing and height dimensions. A photo of the old oil seal or the code stamped on the part also helps. With that data we look for the alternative within the DBH line or other brands we sell. If the exact size is not available, we evaluate a compatible option together before defining the replacement.
