The DBH 1288Pol radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its A 308-R H design combines a sealing lip with a stepped height of 8.00/11.30 mm, intended for housings with a shoulder. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings and gears must be protected. MR Accesorios Industriales carries it as an official brand DBH product.

This item is a seal from the DBH line, identified as 1288Pol. Its nominal dimensions are 35 mm shaft, 58 mm housing and 8.00/11.30 mm height, with A 308-R H design. The double height indicates that the seal has an 8 mm section and an 11.30 mm section, which allows it to seat in housings with a step or with a cover. The radial lip works on the shaft and the outer casing holds the part firmly in the housing. It is a standard replacement part within the radial seals and oil seals category.

Typical applications appear in equipment with continuous rotary motion: gearboxes, reducers, centrifugal pumps, electric motors, spindles and belt or chain drives. In all these cases the seal serves two functions: it prevents oil or grease from escaping the assembly and blocks the passage of contaminants toward the bearings. It is also used in agricultural machinery, conveyors and process equipment where the environment has dust or moisture. If the equipment operates with high vibration or temperature, the condition of the shaft should be checked before replacement.

To install a seal like the 1288Pol, verify that the shaft is 35 mm and the housing is 58 mm, and that the available height accommodates the 8.00/11.30 mm. The shaft must be clean, free of burrs or deep marks on the sealing surface; a scratched surface accelerates leakage. Lubricate the lip with the same grease or oil as the equipment before inserting it, and press it in with a tube or press that pushes evenly on the casing, never on the lip. If the housing has a shoulder, orient the correct side according to the A 308-R H design.

If you need a nearby size or an equivalent, send us the code 1288Pol along with the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we search within the DBH line or from other brands we carry. We can also verify whether the A 308-R H design accepts a variant with a different lip material or with an additional spring, always confirming against the manufacturer's data sheet.
