For rotating equipment where lubricant retention and contamination exclusion are critical, the DBH 1338 radial shaft seal offers a reliable solution. This lip seal fits a 52 mm housing bore and has a 9 mm overall height, featuring the A 378 design. It serves as a vital component in gearboxes, pumps, and motors, keeping oil contained and external particles out. MR Industrial Accessories supplies this brand and provides guidance on selecting the appropriate seal for your specific application.

The DBH 1338 is a radial lip seal with the A 378 designation. Per manufacturer specifications, it installs into a housing bore of 52.00 mm and measures 9.00 mm in height. The seal combines an oil- and grease-resistant elastomer with a spring that maintains lip contact against the shaft.

This seal is commonly found in gearboxes, centrifugal pumps, electric motors, rollers, and transmission equipment. Its primary role is to prevent lubricant leakage and shield bearings from dust, water, and other contaminants. Industries such as manufacturing, agriculture, and process operations rely on such seals to avoid premature bearing wear and unexpected downtime. A failed seal can lead to lubricant loss and bearing contamination, accelerating component degradation.

Proper installation is essential for optimal performance. Ensure the housing and shaft are clean and free of burrs or scratches that could harm the lip. Before pressing the seal into place, lubricate the lip with the same oil used in the equipment. Use an installation tool that applies force to the outer diameter, never directly on the lip. Operating peripheral speed and temperature must remain within the material's limits. If the shaft is worn, consider a seal with a different inner diameter or a repair sleeve. Always verify dimensions against the manufacturer's data sheet.

When seeking an equivalent seal, simply provide part number 1338 or the housing and shaft measurements. MR Industrial Accessories can identify alternatives from other brands or series that deliver the same function. We also assist when mounting space is tight or the original seal is discontinued. Even without the exact part number, sharing dimensions and a photo of the housing allows us to guide you.
