The DBH 1250 seal is a radial lip seal designed to close off the passage of oil, grease or contaminants in equipment with a rotating shaft. Its A 308-R Bidi design allows it to be installed in applications where sealing must act in both directions of rotation or with alternating pressure. With dimensions of 40 mm shaft, 55 mm housing and a height of 8.00/14.00 mm, it suits gearboxes, pumps and motors that require a reliable barrier against leaks and dust.

This item is a radial shaft seal from the DBH brand, identified by the code 1250. Its dimensions are: shaft diameter 40 mm, housing diameter 55 mm and height 8.00/14.00 mm. The A 308-R Bidi design corresponds to a seal with a double lip or bidirectional lip, intended to contain lubricant and exclude particles in both directions of rotation. The variable height indicates that the profile may have an auxiliary lip or dust guard that protrudes from the housing.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases, the seal protects bearings and gears from the entry of dirt and prevents lubricant loss. It is commonly found in agricultural machinery, process equipment and hydraulic systems where the shaft rotates at moderate speeds and the working temperature is stable.

To correctly select a seal such as the DBH 1250, verify that the shaft and housing dimensions match those of the equipment. The 8.00/14.00 mm height must respect the space available in the cavity. The A 308-R Bidi design is suitable when there is rotation reversal or pressure on both sides of the lip. During installation, lubricate the lip with the same oil as the system, avoid striking it and make sure the shaft has no burrs or splines that could damage the seal.

If you need an equivalent seal or a nearby size, the most practical approach is to send us the code 1250 or the dimensions of the original seal (shaft diameter, housing and height). With that data we can look for alternatives within the DBH line or from other brands we supply. We can also advise you if the mounting space is limited or if the A 308-R Bidi design does not suit your application.
