The DBH 1387Vit oil seal is a single-lip radial shaft seal with a spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. It is press-fitted into the housing and runs on the shaft with an oil film that ensures sealing and low friction. It is a key component in gearboxes, pumps and motors, where reliable sealing extends the service life of bearings and gears.

This DBH 1387Vit oil seal has a shaft diameter of 78 mm, a housing diameter of 105.50 mm and a height of 7.50 mm. Its Lx-R AH design combines a spring-loaded sealing lip with an outer section that facilitates installation. The designation 1387Vit identifies the exact size within the DBH line. It is made from elastomers resistant to oils and greases, and its metal structure gives it rigidity to withstand installation pressure.

It is used in equipment with rotating motion and the need to retain lubricant: gearboxes, centrifugal pumps, electric motors, transmission shafts and agricultural or industrial machinery. It is also common in applications with moderate exposure to dust or water, where the spring-loaded lip ensures constant contact on the shaft. It is a standard solution for maintenance and repair of mechanical assemblies.

To correctly select this oil seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Lx-R AH design requires a polished shaft surface free of burrs, and a housing with an entry chamfer to avoid damaging the lip during installation. Lubricate the lip before installing and make sure the spring is on the fluid side to be retained. If the shaft shows wear, consider a neighboring size or a seal with an additional lip.
