The DBH 1288Pol is a radial shaft seal that sits between a rotating shaft and a stationary housing. Its job is to hold lubricant in and keep dust, water and other particles out. Design A 308-R H uses a sealing lip and a stepped height of 8.00/11.30 mm, so it fits housings with a shoulder. Gearboxes, pumps, electric motors and transmission equipment rely on seals like this to protect bearings and gears. MR Industrial Accessories supplies it from DBH.

The 1288Pol belongs to the DBH line of radial seals and oil seals. Its nominal dimensions are a 35 mm shaft, a 58 mm housing and a height of 8.00/11.30 mm, with design A 308-R H. The two height figures mean the seal has an 8 mm section and an 11.30 mm section, which lets it seat in a stepped housing or under a cover. The lip runs against the shaft, while the outer case holds the seal in place.

You will find seals like this in equipment with continuous rotation: gearboxes, reducers, centrifugal pumps, electric motors, spindles and belt or chain drives. In each case the seal does two things: it keeps oil or grease from escaping and blocks contaminants from reaching the bearings. Agricultural machinery, conveyors and process equipment in dusty or wet conditions also use them. If the equipment sees heavy vibration or high temperatures, inspect the shaft surface before you replace the seal.

Before installing a 1288Pol, verify that the shaft measures 35 mm, the housing 58 mm and that the available space accepts the 8.00/11.30 mm height. The shaft must be clean and free of burrs or deep marks on the sealing track; a scratched surface will leak sooner. Coat the lip with the same oil or grease used in the equipment, then press the seal in with a tube or press that applies force evenly on the outer case, never on the lip. If the housing has a shoulder, fit the correct side according to design A 308-R H.

To request a quote for an equivalent, send the part number 1288Pol along with the shaft, housing and height dimensions, and a photo of the old seal if you have one. With that information we look within the DBH line or other brands we carry. We can also tell you whether design A 308-R H accepts a variant with a different lip material or an extra spring, always checking against the manufacturer's data sheet.
