The DBH 9474 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 50.8 mm shaft, 69.88 mm housing and 9.52 mm height place it in medium-size transmission equipment and pumps. It is a wear part: when oil leakage or dirt ingress appears, it is replaced.

This item is a radial shaft seal from the DBH brand, identified by the code 9474. Its dimensions are 50.8 mm shaft diameter, 69.88 mm housing diameter and 9.52 mm height. The Lz design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the outer metal case is held by interference fit in the housing. The combination of inch dimensions converted to millimeters is common in equipment of US origin or in machines that use 2-inch shafts.

Seals of this size are found in gearboxes, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. They also appear in mixers, agitators and conveyors where the shaft passes through a lubricated wall. In all these cases the function is the same: keep the oil or grease inside the assembly and prevent the environment from entering the bearing or gear. When the seal fails, lubricant loss accelerates bearing wear and contaminates the surroundings.

To select the replacement, verify that the shaft diameter, housing diameter and height match those of the original seal. Also check the condition of the shaft: a scratched or worn track means the new lip will not seal even if the dimensions are correct. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and strike only on the metal case, never on the elastomer. If the housing has burrs or is ovalized, correct it before installing.

If the code 9474 is not available or you need a nearby size, send us the dimensions of the old seal or a photo of the part. With the shaft diameter, outer diameter and height we can look for the equivalent in the same brand or in another line we carry. We can also evaluate design variants if the equipment works with high pressure or speed. The more data you give us, the faster we find the option that best suits you.
