MR Accesorios Industriales carries this brand and advises you so you choose the right oil seal for your application.

This item is a DBH 5127 radial shaft seal, identified by its designation 5127. Its dimensions are 42.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 10.00 mm height (h). The Lz design corresponds to a configuration with a sealing lip and dust lip, intended for lubricated rotating shafts. The elastomer and the internal spring work together to maintain contact on the shaft and compensate for small misalignments.

Typical applications for an oil seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In every case, the function is twofold: prevent oil or grease from leaking out and block the entry of dust, water or particles that accelerate wear on bearings and gears. It is a wear part that should be replaced when a visible leak appears or when the equipment is disassembled.

To install a radial shaft seal, check that the shaft diameter and the housing diameter match the dimensions indicated. The shaft surface must be clean, free of burrs and deep marks, and it is advisable to lubricate the lip before inserting it. The seal is inserted perpendicular to the shaft, with a suitable tool that bears on the outer edge, never on the lip. If the shaft shows wear, consider a nearby size or a repair sleeve to restore sealing.
