The DBH 5221Sil radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 42 mm shaft, 65 mm housing and 12 mm height place it in heavy-duty power transmission equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line for industrial maintenance.

This item is a radial shaft seal from the DBH line, identified as 5221Sil. According to the record, it works on a shaft of 42 mm diameter, in a housing of 65 mm and with a total height of 12.00 mm. The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts with permanent lubrication. The sealing lip bears on the shaft and creates a dynamic barrier that prevents oil or grease leaks to the outside.

Seals of this type are used in gearboxes, pumps, electric motors, conveyor rollers, mixers and continuous process equipment. In food, chemical or aggregate processing plants, the seal serves a dual function: it retains lubricant and blocks abrasive dust that would otherwise reach the bearings. That is why it is a critical part in the preventive maintenance plan of any production line.

To select the correct seal, verify that the shaft diameter, housing diameter and height match the original part. Check the condition of the track: a scratched or oval-worn shaft ruins the lip in a few hours. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid hitting it. If the housing has burrs, clean before placing the seal to avoid cutting the lip.
