The DBH 8122 radial shaft seal is a lip seal designed for rotating shafts of 145 mm diameter, with a 170 mm housing and a height of 15/20 mm. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and gears. It is used in gearboxes, pumps, electric motors and industrial equipment where a reliable and durable closure is required.

This item is a radial shaft seal from the DBH brand, identified with part number 8122. Its main dimensions are: shaft diameter 145 mm, housing diameter 170 mm and height 15/20 mm. The A 203 design corresponds to a single-lip configuration with spring, suitable for applications with lubricant and moderate speeds. The standard manufacturing material is nitrile rubber (NBR), although it may vary according to the manufacturer's data sheet; at MR Accesorios Industriales we confirm each specification before requesting a quote.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases, the seal protects the bearings and other internal components against external contamination and prevents oil or grease leaks. It is commonly found in agricultural machinery, mining equipment, treatment plants and pumping systems where the shaft rotates at medium speeds and working conditions demand reliable sealing.

To install this seal correctly, check that the shaft has the proper hardness and roughness, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before installation. When selecting a replacement, take into account not only the dimensions but also the type of fluid, working temperature and peripheral speed. If the A 203 design is not available, we can look for an equivalent alternative that meets the same requirements.
