The DBH 1288Pol radial shaft seal is a lip seal installed between a rotating shaft and a fixed housing to retain lubricant and stop dust, water or particles from entering. Its design A 308-R H 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 transmission equipment where bearings and gears must be protected. MR Accesorios Industriales sells it from DBH.

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 design A 308-R H. 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 runs on the shaft and the outer case keeps the part firm 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 transmissions. 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 works with a lot of vibration or temperature, it is advisable to check the condition of the shaft before replacing.

To install a seal such as the 1288Pol, check that the shaft is 35 mm and the housing is 58 mm, and that the available height allows the 8.00/11.30 mm. The shaft must be clean, with no burrs or deep marks on the sealing track; a scratched surface speeds up leakage. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and seat it with a tube or press that pushes evenly on the case, never on the lip. If the housing has a shoulder, orient the correct side according to design A 308-R H.

To quote an equivalent, send us the part number 1288Pol together 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 other brands we sell. We also tell you whether design A 308-R H accepts a variant with another lip material or with an additional spring, always confirming against the manufacturer's data sheet.
