MR Accesorios Industriales sells it as a brand for maintenance and repair of industrial equipment.

This item is a DBH 9789 radial shaft seal, identified by its designation 9789. Its dimensions are 27.00 mm shaft diameter, 39.00 mm housing diameter and 10.50 mm height. The Lx design corresponds to a seal with a single sealing lip and spring, intended for rotating shafts with lubrication. The DBH nomenclature groups general-purpose seals used in power transmission and rotating equipment.

It is used in pumps, electric motors, gear reducers, gearboxes, mixers and process equipment. Also in machine tools, conveyors and hydraulic systems where oil or grease must be retained and bearing contamination prevented. It is a wear part: when lubricant leakage or dirt ingress appears, it is replaced.

To select the seal, verify that the shaft diameter, housing and height match the dimensions of the original part. Check the condition of the shaft: if it has scratches or wear, the lip will not seal properly. During installation, lubricate the lip, use a suitable pressing tool and avoid striking it. If the equipment operates at high temperature or speed, consult the manufacturer's data sheet to confirm the lip material.
