The SKF V-ring seal of the VAX V series is an axial sealing element that mounts on the shaft and rotates with it. Its flexible elastomer lip rests against a perpendicular face, generally the front face of a bearing or a housing, and blocks the entry of dust, water and particles. It is widely used in applications where space is limited and a reliable barrier is needed without machining the housing. MR Accesorios Industriales sells this line.

The VAX V series designation is read in parts. The letters VAX identify the category of SKF V-ring seals, and the final V indicates the profile variant. The number preceding the letters indicates the nominal shaft diameter for which the seal is intended: for example, 400 VAX V corresponds to a 400 mm shaft. There is no need to memorize part numbers: the number and letters already tell you which shaft size it covers. For other sizes, the same logic repeats by changing the initial number.

In Argentine industry, SKF V-rings appear in mining, cement, steel, aggregate processing and material handling equipment. They are also found in pumps, mixers, gear reducers and conveyor belt rollers, where dust or moisture attacks the bearings. Their mounting on the shaft makes them ideal for protecting bearings in dirty environments, since they act as a dynamic deflector and reduce wear on the main seal. MR Accesorios Industriales offers them for these demanding applications.

To choose a V-ring correctly, take into account the shaft diameter, rotation speed and type of contaminant. The lip should rest with slight interference on the sealing face; if the contact is excessive, heat and premature wear are generated. Lubricating the lip with compatible grease or oil helps reduce friction. Alignment between the shaft and the contact face is key: large misalignment can open the lip and lose sealing. In assemblies with high vibration, it is advisable to periodically check the condition of the elastomer.

Regarding equivalences, V-rings are interchanged between manufacturers by shaft number and profile, but not all elastomers or tolerances are the same. If you need to replace a seal from another brand, the safest approach is to compare the shaft diameter, overall width and lip shape. The VAX V series is usually compatible with other V-ring lines of similar dimensions, provided the mounting space allows it.

If you already have the seal part number, send it by WhatsApp to MR Accesorios Industriales and we will quote you. You can also send us a photo or the shaft and support face measurements so we can help you identify the SKF V-ring you need. At MR Accesorios Industriales we know difficult assemblies and advise you so that sealing works from day one.
