The DBH 9853Vit radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and stop the entry of dust, water or particles. With a 12.5 mm shaft diameter, 22.5 mm housing and 5 mm height, it is a small size found in compact equipment: small electric motors, pumps, light gearboxes and transmission mechanisms. MR Accesorios Industriales carries this brand and advises you so you can choose the right oil seal according to the shaft, the housing and the type of stress it will be subjected to.

This item is an Lx design oil seal, with the dimensions shown in its designation: 12.5 mm shaft, 22.5 mm housing and 5.00 mm height. The Lx design corresponds to a single-lip oil seal with a metal case and elastomeric sealing lip, intended for rotating shafts with lubrication. The DBH 9853Vit nomenclature identifies the part within the brand's radial seal line, and those three values are what you need to verify before ordering: any variation in shaft diameter or housing changes the fit and the oil seal will not seal properly.

Typical applications for an oil seal of this size are in equipment where space is limited and speeds are not extreme. It is found in low-power electric motors, small centrifugal pumps, worm gearboxes, light transmission cases, fans and machine tools. In all those cases it performs the same function: keeping the oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used as a secondary closure on control shafts and selectors.

To install it properly, the shaft must be clean, free of burrs or tool marks, and it is advisable to lubricate the lip before inserting it so as not to damage it during assembly. The oil seal seats in the housing with a firm fit, without blows that deform the case. When selecting, take into account the rotation speed, working temperature and the fluid to be retained: an oil seal for mineral oil is not the same as one for grease or for an environment with water. If the shaft shows wear, consider an oil seal with an auxiliary lip.

If you need an equivalent, send us the code 9853Vit along with the shaft and housing dimensions, a photo of the old part and, if possible, the type of equipment where it is mounted. With that data we will tell you the alternative in the same series or in another DBH oil seal line that adapts without modifying the machining. We can also advise you if the housing accepts an oil seal of a different height or if it is better to change the design for one with dust protection.
