When a rotating shaft needs reliable sealing in a tight axial space, the DBH 1253 oil seal fits the bill. Its A 308-R H profile features a stepped height of 9 to 17 mm, so it sits properly in a shouldered cavity. This seal keeps lubricant where it belongs and blocks dust and moisture from entering. You will find it in gearboxes, pumps, motors, and transmission shafts where space is limited.

The DBH 1253 is built for a 32 mm shaft and a 59 mm housing bore. Its height varies from 9 to 17 mm thanks to the A 308-R H design. That step means the seal has a thicker cross-section, made to rest against a shoulder or step in the housing. The lip rides on the shaft, holding oil or grease in while keeping contaminants out.

You will see this seal in gearboxes, centrifugal pumps, electric motors, compressors, and power transmission setups. It also shows up on mixer shafts, conveyors, and agricultural or industrial machinery that runs continuously in dirty conditions. In every case, it protects bearings and gears from premature wear by maintaining the lubricant barrier.

Choosing the right seal starts with matching the shaft and housing diameters to the values above. The 9 to 17 mm height must align with the cavity depth; without a proper shoulder, the lip may not seat correctly. During installation, coat the lip with the same oil used in the equipment, handle it without impacts, and check the shaft for burrs or marks that could harm the seal.
