Sealed type Four row tapered roller bearings replace (NSK)
KVS, KVE (sealed type, 4-row tapered roller bearings) are the model representation rules of NSK in Japan. Our FV commonly known as TQOS series rolling mill bearings. KVE: Old design sealing system KVS: Innovative sealing system, better space utilization FV engineers have sorted out the models and dimensions of KVE and KVS series rolling mill bearings. If you need to purchase such bearings, please contact us.
