The DBH 1338 radial shaft seal is a lip seal designed to block the passage of lubricant and prevent contaminants from entering rotating equipment. It is mounted in housings of 52 mm diameter and has a height of 9 mm, with A 378 design. It is a key part in gearboxes, pumps and motors, where oil must stay inside and dirt outside. MR Accesorios Industriales carries this brand and advises you on choosing the right seal for your application.

The DBH 1338 is a radial-type seal with a sealing lip, identified by the A 378 design. According to the manufacturer's data, it is installed in a housing of 52.00 mm diameter and has a total height of 9.00 mm. This seal is made with elastomer resistant to oils and greases, and a spring that keeps the lip in contact.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. In all these cases, the seal prevents lubricant leaks and protects the bearings from dust, water and particles. It is commonly found in industrial machinery, agricultural equipment and process lines where sealing reliability is critical. If the seal fails, lubricant escapes and the bearings become contaminated, which accelerates wear and can cause unplanned downtime.

To install a radial shaft seal, keep in mind the cleanliness of the housing and the shaft, and verify that there are no burrs or marks that could damage the lip. Lubricate the lip with the same oil as the equipment before inserting it, and use an installation tube that presses on the outer diameter, never on the lip. The peripheral speed and operating temperature must be within the material's limits. If the shaft shows wear, consider a seal with a different inner diameter or a repair sleeve. Always confirm the dimensions against the manufacturer's data sheet.
