The DBH 9256 radial shaft seal is a lip seal designed to close off the passage of oil or grease on rotating shafts, preventing leaks and the entry of dust or water. Its A 154 design combines a sealing lip with a metal body that is press-fitted into the housing. It is used in gearboxes, pumps, electric motors and power transmission equipment, where sealing reliability is key to avoiding downtime and lubricant loss.

This DBH 9256 oil seal has a shaft diameter of 31 mm, a housing diameter of 52.40 mm and a height of 15.50/10.00 mm. The A 154 design corresponds to an oil seal with a sealing lip and a reinforced body, suitable for press fitting into machined housings. It is a component of the radial seal category that MR Accesorios Industriales sells as the official brand DBH. The stepped height of 15.50/10.00 mm allows it to be adapted to different housing depths depending on the equipment design.

Typical applications for this oil seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all these cases, the oil seal prevents lubricant leakage and protects bearings and gears from the ingress of contaminants. It is also used in agricultural machinery, material handling equipment and hydraulic systems where the shaft rotates inside a fixed housing. Its A 154 design makes it suitable for moderate peripheral speeds and continuous operating conditions.

To select this oil seal correctly, verify that the shaft diameter is 31 mm and the housing diameter is 52.40 mm. The mounting height must match the available depth: 15.50 mm or 10.00 mm depending on how it is installed. The lip must remain lubricated and undamaged; using a suitable mounting tool is recommended so as not to deform the seal. If the shaft shows wear or roughness, consider an oil seal with an auxiliary lip or a wear sleeve. Cleaning the housing and the shaft before mounting is essential to achieve lasting sealing.
