The DBH 1255 seal is a single-lip radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Its standard dimensions make it suitable for standard housings in power transmission equipment, pumps and electric motors. MR Accesorios Industriales supplies this official brand as part of its line of seals and oil seals, with technical advice to choose the right size according to the shaft and housing.

This item is a DBH 1255 radial shaft seal, with the following dimensions: shaft diameter 31.75 mm, housing bore 41.27 mm and height 4.78 mm. The Mz design indicates a configuration with a sealing lip and metal case, suitable for applications requiring a barrier against oil or grease. The 1255 designation identifies the exact size within the DBH line, and these values must match the shaft and housing to ensure correct installation.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, its function is to prevent lubricant leaks and protect bearings from the ingress of dust, water or particles. It is commonly found in industrial machinery, agricultural equipment and production lines where sealing reliability is critical to avoid unplanned downtime.

To select this seal correctly, check that the shaft diameter is 31.75 mm and the housing bore is 41.27 mm, with a height of 4.78 mm. The Mz design suggests a sealing lip that requires a ground shaft surface lubricated at the time of installation. It is important that the housing has an entry chamfer so as not to damage the lip during installation. If the shaft shows wear, consider the possibility of using a repair sleeve or an alternative size.
