The DBH 1377/85 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. With dimensions of 20.00 mm shaft, 43.00 mm housing and a height ranging from 7.00 to 8.00 mm, this component is ideal for applications where space is critical. Its A 135 design ensures efficient sealing under demanding conditions. MR Accesorios Industriales carries this official brand, offering a reliable solution for your equipment.

This DBH 1377/85 seal is identified by its designation and standard dimensions: shaft diameter of 20.00 mm, housing diameter of 43.00 mm and a height ranging from 7.00 to 8.00 mm. The A 135 design corresponds to a single-lip configuration with a spring, suitable for rotating shafts. Made with high-resistance elastomers, it offers durability against oils and greases. It is the right part when you need to replace worn seals and maintain sealing in your machinery.

Typical applications of this seal include pumps, electric motors, gear reducers, gearboxes and power transmission equipment. In industry, it is used to protect bearings and shafts against the ingress of dust, water or particles, and to prevent lubricant leaks. Its compact size makes it suitable for tight spaces where effective sealing is required. It is common in equipment in the food, chemical and process industries, provided the materials are compatible with the fluids handled.

For correct installation, check that the shaft and housing are clean and free of burrs. Lubricate the seal lip with the same oil or grease used in the equipment before inserting it. Installation must be done with suitable tools, applying uniform pressure on the outer diameter, never on the lip. Make sure the seal sits perpendicular to the shaft. If the shaft shows wear, consider the possibility of using a wear sleeve. Selection must take into account speed, temperature and type of fluid.
