NTN Corporation (hereafter NTN) has developed and commercialized a double row angular contact ball bearing “BSTU series” for machine tool ball screw support units. NTN has been marketing the “Ball screw support single row thrust angular contact ball bearing (BST series)” as a machine tool precision bearing (ALTAGE series). This time NTN has developed and commercialized a high load capacity double row angular contact ball bearing unit, and added it to the ULTAGE series. The single row BST series has been applied (in the form of multiple row assembly of single row angular contact ball bearings) primarily by Asian manufacturers, and the product developed this time is intended to respond to standard specifications of European manufacturers. In Europe, double row angular contact ball bearing units with housing-fixing holes on outer rings are generally used. This bearing has the world's highest load capacity as a ball screw support bearing, and attains low torque (starting torque = 1/2 of other makes) and high dust proofing performance through use of a new type of seal. NTN names the bearing “BSTU (Ball screw Support angular contact Thrust ball bearing Unit) series”. In addition to single body type, duplex type is also available in the BSTU series. NTN will market this product globally, as well as in the European market.
