The DBH 1236/85 seal is a single-lip radial seal that mounts on the shaft and closes against the housing to retain oil or grease and stop dust and water from entering. Its A 090 design and stepped height of 8.00/10.50 mm make it suitable for gearboxes, pumps and motors where axial space is limited. MR Accesorios Industriales carries it as part of its line of seals and oil seals for maintenance and replacement.

This seal corresponds to the DBH designation 1236/85 and works on a shaft with a diameter of 41 mm and a housing of 53 mm. The total height is 8.00/10.50 mm, which indicates a profile with two steps: the sealing lip rests on the lower-height area and the outer body covers the taller one. The A 090 design defines the geometry of the lip and the spring, intended for rotating shafts with permanent lubrication. It is a standard replacement component within the radial shaft seal category.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. It is also used in rollers and machine tool shafts where lubricant must be contained and external contamination prevented. In all cases, it is advisable to check that the shaft does not show wear or grooves on the sealing track, because that shortens the service life of the lip.

For installation, clean the housing and the shaft, lubricate the lip with the same oil or grease used in the equipment and press the seal in perpendicularly until it seats at the bottom. Do not strike or deform the lip. When selecting a replacement, take into account the shaft diameter, housing diameter, available height and type of fluid. If the shaft is damaged, consider a wear sleeve or a nearby size before installing the new seal.

If you need an equivalent or a different size, send us the code 1236/85 along with the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we can look for an alternative within the DBH line or other brands we carry. We can also guide you if the axial space allows a standard height instead of the stepped one.
