The DBH 1250 is a radial shaft seal that keeps oil, grease and contaminants from escaping or entering around a rotating shaft. Its A 308-R Bidi lip design works in both directions of rotation, so it fits equipment where the shaft reverses or pressure acts on either side of the lip. With a 40 mm shaft, a 55 mm housing and a height of 8.00/14.00 mm, it is used in gearboxes, pumps and motors that need a dependable barrier against leaks and dust.

The seal carries the DBH code 1250 and the A 308-R Bidi designation. The dimensions to check are shaft 40 mm, housing 55 mm and height 8.00/14.00 mm. The Bidi lip seals in both directions of rotation and under alternating pressure, while the two-part height points to an auxiliary lip or dust guard that sits outside the housing bore.

You will find this seal in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In each case it protects bearings and gears from dirt and holds lubricant in place. It is common in agricultural machinery, process equipment and hydraulic systems where shaft speed is moderate and working temperature stays stable.

When selecting a DBH 1250, match the shaft and housing dimensions to the equipment and confirm that the 8.00/14.00 mm height fits the cavity. Choose the A 308-R Bidi design when the shaft reverses or pressure can act on both sides of the lip. During installation, lubricate the lip with the system oil, avoid striking it and make sure the shaft is free of burrs or splines that could cut the seal.

If you need an equivalent, send the code 1250 or the original seal dimensions: shaft diameter, housing diameter and height. With that information we can look for alternatives within the DBH line or from other brands we supply, and advise you if the mounting space is tight or if the A 308-R Bidi design does not suit your application.
