The DBH 8939 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and stop the ingress of dust, water or particles. Its dimensions are 65 mm shaft, 80 mm housing and 8 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment, where correct sealing defines the service life of the bearings and the assembly.

This item is a radial shaft seal from the DBH line, identified with part number 8939. It runs on a 65 mm diameter shaft, fits into an 80 mm housing and has a total height of 8 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with grease or oil lubrication. The elastomeric lip bears on the shaft and the spring keeps it in constant contact, while the metal body secures the fit in the housing.

Typical applications appear in rotating equipment: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. It is also found on belt or chain drive shafts, where lubricant must be contained and dirt kept out. In all these cases the seal protects the bearings and extends maintenance intervals, provided the shaft and housing are in good condition and the rotational speed is compatible with the lip material.

To install it, check that the shaft measures 65 mm and the housing 80 mm, with no burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and apply force on the outer ring, never on the elastomer. The 8 mm height should sit flush or slightly recessed depending on the housing design. If the shaft shows wear, consider a repair sleeve or a nearby size before fitting the seal.

If you need an equivalent or a different size, send us part number 8939 together with the shaft, housing and height dimensions, and the type of lubricant. With that data we look for alternatives within the DBH line or from other brands we carry, respecting the Lx design and the operating temperature range. We can also advise you if the space allows a double-lip seal or a variant with dust lip, depending on the contamination level of the equipment.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals.
