The DBH 1330 is a radial shaft seal from the DBH 1330 series, built to keep oil or grease inside rotating equipment. It uses the A 378 design, a single-lip profile with a spring. Its dimensions are 42 mm shaft, 42 mm housing, and 10 mm height. MR Industrial Accessories supplies this seal and helps you confirm it fits your application.

This oil seal belongs to the DBH 1330 series. The A 378 designation indicates a single lip with a spring, which is a common choice for rotating shafts. With a 10 mm height, it fits into shallow housing bores. It is a general-purpose seal, not intended for high-pressure or extreme-speed service.

Radial shaft seals like the DBH 1330 are found wherever a shaft turns inside a housing and lubricant must stay in while contaminants stay out. Typical locations include gearboxes, centrifugal pumps, electric motors, speed reducers, and rollers. They also appear in agricultural machinery and transmission equipment. The seal retains oil or grease and helps block dust and water from reaching the bearing.

When installing a DBH 1330, inspect the shaft for burrs or wear and make sure the housing is clean. Apply the same oil or grease used in the equipment to the lip before pressing the seal in. Use a tube or driver of the correct diameter to tap it evenly and avoid deforming the seal. If the shaft shows a deep groove, consider a seal with an auxiliary lip or a wear sleeve. Speed, temperature, and lubricant type all affect the final selection.

To find an equivalent, send the full part number, the shaft, housing, and height dimensions, and a photo of the old seal. With that information, we can locate the corresponding reference in our seals line. If the A 378 design does not suit your application, we can suggest other designs or brands. The goal is to keep your equipment running without delays for a small component.
