The DBH 1175 is a radial shaft seal built to the A 378 design. It keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching rotating components. Because it takes up little room, it fits equipment where the seal cavity is tight and a dependable barrier is still needed.

The figures to work with are a 42 mm housing bore and a 7 mm height. The A 378 designation describes how the lip and metal body are put together, which is what produces the sealing action against the shaft. One detail to keep in mind: the shaft diameter does not appear on this page, so confirm it against the manufacturer's data before ordering, or send us your measurements and we will check it with you.

Seals in this family show up on pumps, electric motors, gearboxes, conveyor rollers and similar rotating machinery. Their job is twofold: hold the oil or grease inside the assembly, and keep outside matter such as grit, moisture or metal particles away from bearings and bushings. Doing that consistently is what keeps those parts running for their expected service life.

Choosing the right seal means matching the shaft and housing dimensions, then checking the lubricant in use, the temperature the equipment sees and how fast it turns. During installation, use the proper drivers so the lip does not get nicked, coat the lip with lubricant beforehand and make sure everything seats squarely. If the shaft surface is worn, look at a wear sleeve or a different size rather than pressing the same seal back on.
