The DBH 6143 is a radial shaft seal from the 6143 series, with a designation that corresponds to its numeric code. Its standard dimensions are 42.86 mm for the shaft diameter (d), 66.57 mm for the housing bore diameter (D) and 12.70 mm height (h). The A 014 design indicates a specific construction configuration, with a sealing lip and reinforced body for press-fit installation. This type of seal is manufactured in elastomers resistant to oils and greases, and its geometry ensures uniform contact on the rotating shaft.

Typical applications include gearboxes, centrifugal pumps, electric motors, compressors, spindles and power transmission equipment. In these systems, the seal prevents lubricant leaks and blocks the entry of dust, water or particles, extending the service life of bearings and gears. It is also used in agricultural machinery, process equipment and industrial assemblies where a reliable barrier is required between the lubricated interior and the external environment.

To select the seal correctly, verify that the shaft and housing dimensions match those indicated. The shaft surface must be ground and free of burrs, with hardness and roughness suitable for the lip. The housing must have an entry chamfer and a depth that allows the full height to be seated. During installation, lubricate the lip and use an installation tool to avoid damage. Peripheral speed and operating temperature must be within the limits of the elastomer.
