|---|---|---|---|---|
| VA301 | SKF | Bearing for traction motors. | NU 322 ECM/C4 VA301 | Cylindrical roller bearings |
| VA305 | SKF | VA301+specially control. | NJ 326 ECM/C4 VA305 | Cylindrical roller bearings |
| VA228 | SKF | For applications where speeds are below 200 rpm and temperatures range from –45 to +350 C. These unique bearings are fitted with a coronet cage made of graphite. During operation, the cage releases minute amounts of graphite powder that lubricate the bearing. | 6305-2Z/ VA228 | High temperature bearings and bearing units |
| VA208 | SKF | With a graphite cage. However, instead of a coronet cage, the 2Z/VA208 has a segmented graphite cage to separate the balls and provide the necessary lubricant. These cost-effective bearings are designed for applications where speeds do not exceed 100 rpm. | 6220-2Z/ VA208 | High temperature bearings and bearing units |
| V | SKF | Full complement bearing (without cage). | Cylindrical roller bearings, CARB toroidal roller bearings | |
| VA | SKF | Application oriented variants. | 6005-2Z/ VA 201 | |
| VA201 | SKF | Packed with a polyalkylene glycol/graphite mixture, these bearings can be used in applications where speeds do not exceed 250 rpm and temperatures range from –40 to +250 C. To further protect the bearing from corrosion and enhance running properties, all earing surfaces are coated with manganese phosphate, which also enhances adhesion of the lubricant to the metal. | 6005-2Z/ VA201 | High temperature bearings and bearing units |
| UPG | SKF | Single row angular contact ball bearing with tolerance class UP for universal pairing in O-arrangement or X-arragement. When arranged back-to-back or face-to-face there will be a light preload. | 6200TN/ UPG | |
| UP | SKF | Dimensional accuracy in accordance with ISO tolerance class 4, running accuracy better than ISO tolerance class 4. | 234714 BM/ UP | |
| U2/U4 | SKF | Single row metric tapered roller bearings with reduced tolerance on the total width.The numbers (2, 4, etc.) characterize the tolerance and meet the standards for tapered roller bearing performance "K". |
