The DBH 1249 oil seal is a single-lip radial seal with a spring, designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 33 mm shaft diameter, 55 mm housing and 8.50/13.50 mm height make it suitable for gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

This item is a DBH 1249 radial shaft seal, with a shaft diameter of 33 mm, a housing diameter of 55 mm and a height of 8.50/13.50 mm. Its A 308-R H design corresponds to a sealing lip with a spring that guarantees tightness under rotation conditions. The stepped height allows a firm fit in housings with a shoulder. It is a direct replacement part for equipment that requires oil or grease containment and protection against dust and water.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems. In these equipment, the seal prevents lubricant leaks and the entry of particles that accelerate wear on bearings and gears. It is also used in agricultural machinery, construction equipment and process lines where sealing reliability is critical to avoid unscheduled downtime.

For correct mounting, verify that the shaft has adequate hardness and roughness, without burrs or marks. Lubricate the lip with the same oil or grease as the equipment before inserting it. The seal must be perpendicular to the shaft and flush with the housing or slightly recessed, depending on the design. Avoid hitting the lip during installation. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an equivalent seal or a nearby size, send us the full part number, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for a compatible alternative in our seals and oil seals line. We can also advise you on the lip type, material and spring according to the temperature and speed conditions of your equipment.
