The DBH 5403 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and stop the ingress of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment where a shaft rotates inside a housing. Its Lx design and its dimensions of 27 mm shaft, 41 mm housing and 10 mm height make it a common replacement part in industrial maintenance.

This item is a DBH 5403 radial shaft seal, identified by its designation 5403. Its dimensions are 27 mm shaft diameter (d), 41 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The DBH brand is an official brand that MR sells, so the code can be checked against the manufacturer's data sheet before confirming the order.

Typical applications of a seal with these dimensions appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases the seal performs two functions: preventing oil or grease from escaping through the shaft passage and preventing contaminants from entering from outside. That is why it is found in preventive maintenance and in repairs of equipment working with continuous rotation.

To install it properly, check the condition of the shaft and housing: no burrs, no deep scratches and with the appropriate roughness for the lip. The seal is placed with the lip facing the lubricant side and seated evenly, without hitting it sideways. Before installing it, lubricate the lip with the same grease or oil as the equipment. If the shaft is worn, consider a repair sleeve or a different size.

If you need an equivalent or a nearby size, the most practical thing is to send the code 5403 together with the shaft, housing and height dimensions. With that data, the same Lx design can be found in another brand or a seal with close dimensions, always confirming against the manufacturer's data sheet. A photo of the old part and the housing also helps to avoid interpretation errors.
