The DBH 8414 radial shaft seal is a lip seal designed for rotating shafts with a 20 mm diameter, a 31 mm housing bore and a 7 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and bushings. It is a wear part that is replaced during preventive or corrective maintenance of pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales supplies this brand for the Argentine industrial market.

This item is a radial shaft seal from the DBH line, identified by the code 8414. Its nominal dimensions are 20.00 mm shaft diameter, 31.00 mm housing bore diameter and 7.00 mm height. The Mz design corresponds to a configuration with a sealing lip and metal case, suitable for rotating shafts. The lip, generally made of elastomer, runs on the shaft surface and creates a dynamic barrier against oil or grease leaks. The outer case ensures a firm fit in the housing.

Typical applications for a 20x31x7 mm oil seal include small centrifugal pumps, low-power electric motors, speed reducers, gearboxes, compressors and belt- or chain-driven transmission equipment. It is also used in machine tools, industrial washing equipment and hydraulic systems where lubricant must be contained at the shaft rotation point. In all cases, it protects nearby bearings and bushings from external contamination.

To select this oil seal correctly, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be free of burrs, scratches or excessive wear; a damaged shaft accelerates lip failure. During installation, lubricate the lip with the same oil or grease used in the equipment and avoid striking it. If the housing is loose or deformed, the seal will not seal properly. The 7 mm height must match the cavity depth for correct seating.

If you need an equivalent oil seal or a nearby size, the most practical approach is to send us the code 8414 or the dimensions 20x31x7 mm via WhatsApp. You can also indicate the type of equipment, the brand of the assembly and a photo of the original part.
