The DBH 5853 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 33 mm shaft diameter, 42.50 mm housing diameter and 8.00 mm height place it in compact-size applications, such as gearboxes, pumps and electric motors. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified by the code 5853. Its main attributes are: shaft diameter (d) of 33 mm, housing diameter (D) of 42.50 mm and height (h) of 8.00 mm. Design Lz corresponds to a single-lip configuration with spring, designed for rotating shafts with lubrication. The sealing lip runs on the shaft and the outer case fits into the housing, creating a barrier against leaks and contaminants.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases it performs the function of confining the oil or grease inside the assembly and preventing the entry of external agents that accelerate the wear of bearings and gears. It is a frequently maintained part in industrial plants, factories and mobile equipment.

To mount this seal correctly, verify that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, using a tube or socket that rests on the metal case, never on the lip. The selection must consider the shaft speed, working temperature and the type of fluid to be retained; if in doubt, ask us with the data of your equipment.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the full code, a photo of the part and the dimensions measured with a caliper: shaft diameter, housing diameter and height. With that data we can look for alternatives within the same series or from other brands we carry. We can also advise you if design Lz is not the most suitable for your application.
