The DBH 1281 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating equipment. It mounts on 58 mm shafts and fits into a 103 mm housing, with a height of 12 to 20 mm depending on the A 308 design. It is a key component in pumps, electric motors, gear reducers and gearboxes, where reliable sealing extends bearing service life and reduces maintenance downtime.

This DBH 1281 oil seal has a shaft diameter of 58 mm, a housing diameter of 103 mm and a height ranging from 12 to 20 mm. Its A 308 design corresponds to a radial shaft seal with a sealing lip and metal case, intended to retain oil or grease in applications with rotating motion. The 1281 designation identifies the exact size within the DBH line, and it is essential to verify these dimensions before replacing a worn part.

Typical applications for this oil seal include centrifugal pumps, electric motors, speed reducers, gearboxes and power transmission equipment. In all these cases, the seal prevents lubricant leaks and protects the bearings from dust, water or particles that accelerate wear. It is also used in agricultural and industrial machinery where a dirty environment demands efficient sealing.

To correctly select an oil seal, take into account the shaft diameter, the housing diameter and the available height. It is important that the shaft surface is in good condition, free of grooves or wear, and that the housing has the right finish to ensure a firm fit. The lip must be lubricated before assembly and oriented toward the fluid side to be retained. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
