The DBH 9178Vit is a radial shaft seal built for a 155 mm shaft, a 180 mm housing bore and a 15 mm height. It keeps lubricant inside the assembly and blocks contaminants from entering, which makes it a routine replacement item on medium and large pumps, gearboxes and electric motors. MR Industrial Accessories supplies it through its seals and oil seals line for industrial maintenance work.

The part belongs to the DBH range and carries the designation 9178Vit. Read the sizes as shaft 155 mm, housing bore 180 mm, height 15.00 mm. Its Mx-R-AH configuration pairs a retaining lip with an auxiliary dust lip, a layout chosen for moderate dust or dirt exposure. The sealing lip uses elastomeric material and the outer body is normally metallic; the manufacturer's data sheet is the reference for these construction details.

Seals of this size show up on centrifugal pumps, speed reducers, electric motors, conveyor rollers and power transmission equipment. In each case the seal sits on the rotating shaft inside a fixed housing, holding oil or grease in and the outside environment out. It plays a key role in stopping leaks and in protecting bearings and gears over time.

When selecting a replacement, match all three dimensions to the shaft and housing on your equipment. Peripheral shaft speed, operating temperature and the lubricant in use all affect which lip material fits best. The Mx-R-AH design handles dusty conditions well, though checking chemical compatibility with the fluid being retained is always worthwhile.
