For maintenance teams dealing with lubricant loss around a rotating shaft, the DBH 1251Vit radial shaft seal is a direct replacement option. It fits a 39 mm shaft, a 50 mm housing bore and a 7 mm width, and its Lx-R H configuration combines a sealing lip with a reinforced outer body. This seal is press-fit into gearboxes, covers and crankcases. Because it is a wear item, leakage or a loose lip usually signals it is time to replace it.

The designation 1251Vit identifies a DBH lip seal built to the Lx-R H design. In practical terms, that means a single sealing lip that holds oil or grease on one side while keeping dust and water out, supported by a stiffer case for a secure fit in the housing. The three critical measurements are shaft 39 mm, housing 50 mm and width 7 mm. DBH is one of the seal brands we supply, so the replacement maintains the dimensions and materials intended for the original application.

Seals in this size range show up in gearboxes, pumps, electric motors, line shafts and process equipment. You will also find them in agricultural implements, transport equipment and plant machinery where a rotating shaft needs to be isolated from its surroundings. How long one lasts depends on shaft speed, operating temperature and how clean the lubricant stays. Once the lip starts to leak, oil can travel into unwanted areas and carry contaminants back into the mechanism.

Installation calls for a close look at the shaft surface: no burrs, no deep grooves, and a housing that is clean and undistorted. Coat the lip with the same lubricant used in the equipment, then press the seal in squarely using a tube that contacts the outer edge only, never the lip. If the shaft is worn, a repair sleeve is worth considering. Peripheral speed and lubricant type both affect selection, so if anything is unclear, send us the equipment details.

If you are sourcing an equivalent, message us the code 1251Vit or the dimensions 39 x 50 x 7 mm. A photo of the old seal plus the shaft and housing diameters and the lubricant type helps us verify the exact size within the DBH line. We supply this brand as part of our seals and oil seals range.

To wrap up your inquiry, contact us on WhatsApp with the code 1251Vit and the dimensions or a photo of the part. We will confirm whether this is the reference you need or whether a variant fits better. Our radial shaft seal offering covers multiple brands and sizes so you can complete the replacement without keeping equipment down.
