The DBH 8452 is a radial shaft seal that closes the gap between a rotating shaft and its housing, keeping lubricant in and contaminants out. Its dimensions are shaft 27 mm, housing 45.4 mm and height 6.6/10.4 mm, with design A 104. You will find it in gearboxes, pumps, motors and other power transmission equipment. MR Industrial Accessories supplies this brand and can help you confirm the size before you request a quote.

The part number 8452 belongs to the DBH line of radial shaft seals. Reading the size: d = 27 mm is the shaft diameter, D = 45.4 mm is the housing bore, and h = 6.6/10.4 mm is the height. The two height figures indicate that the lip stands out from the seat; the 6.6 mm section sits in the bore while the 10.4 mm is the overall assembled height. Design A 104 describes the lip and metal case geometry for rotating shafts with permanent lubrication.

Typical service includes gearboxes, centrifugal pumps, electric motors, mixers, conveyors and farm machinery. The seal is also chosen where dust or splashes are present, since it holds oil or grease in the bearing area and blocks particles and water. Because it is a wear part, a hardened lip or a scored shaft will cause leakage and the seal will need replacement.

Before installation, confirm the shaft is clean and free of burrs or grooves, and that the lip running surface has the correct hardness and finish. Coat the lip with the same lubricant used in the unit, then press the seal in squarely, without hitting it on one side. If the shaft shows wear, an auxiliary lip version may be considered. Speed, temperature and lubricant type all affect selection and should be checked against the manufacturer's data.
