The DBH 5137 radial shaft seal is a lip seal mounted on rotating shafts to retain lubricant and exclude contaminants. With dimensions of 12 mm shaft diameter, 30 mm housing bore and a height of 8.00/13.00 mm, this A 245 design model is used in gearboxes, pumps, electric motors and power transmission equipment. Its function is to protect bearings and gears, extending the service life of the assembly and reducing oil or grease losses.

The DBH 5137 is a radial shaft seal with a sealing lip. Its standard dimensions are 12 mm shaft diameter (d), 30 mm housing bore diameter (D) and a total height of 8.00/13.00 mm (h). The A 245 design corresponds to a specific lip and case configuration that ensures sealing under rotating conditions. It is made with elastomers resistant to oils and greases, and a metal case that facilitates press-fit installation in the housing.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive systems. In all these machines, the seal prevents lubricant leaks and the entry of dust, water or particles that accelerate wear on bearings and gears. It is a critical part for maintaining reliability and reducing maintenance costs.

To select the seal correctly, verify that the shaft and housing dimensions match those of the equipment. The 8.00/13.00 mm height indicates that the seal can adapt to housings with different depths. During installation, lubricate the lip with the same oil or grease used in the equipment, insert it perpendicularly and avoid striking it. If the shaft shows wear or scoring, consider replacement or the use of a repair sleeve.
