Contributing to Elevator Speed, Safety and Security and Passenger Comfort
NSK Ltd. (NSK; Headquarters: Tokyo, Japan) today announced that its low-noise, low-vibration self-aligning roller bearings for elevators have been selected for use in Toshiba’s elevators in the TOKYO SKYTREE®. Standing 643 meters in height, TOKYO SKYTREE® is the world’s tallest free-standing broadcasting tower. TOKYO SKYTREE® is located in Tokyo’s Sumida Ward and operated by Tobu Railway Co. Ltd. and Tobu Tower Sky Tree Co., Ltd.
The tower is scheduled to open on May 22, 2012.
Designed by Toshiba Elevator and Building Systems Corporation, the elevators connecting the ground level and the tower’s first observation deck 350 meters above ground are the fastest large-capacity elevators in Japan. They ascend and descend at a speed of 600 meters per minute and can carry a maximum of 40 passengers each. NSK’s low-noise, low-vibration self-aligning roller bearings specially designed for elevators help the elevators’ drive system operate quietly and smoothly.
The Tokyo Sky Tree® is also equipped with service elevators by Toshiba Elevator and Building Systems Corporation which travel 464.4 meters, the longest distance of any elevator in Japan. The same NSK bearings also contribute to the safety and speed of these service elevators.
Demand for high-speed elevator drive systems used in high-rise buildings is growing worldwide, especially in emerging countries as infrastructure grows. NSK intends to intensify marketing of its dedicated elevator bearings designed for these systems. NSK will also draw from its comprehensive technological capabilities acquired from developing bearings for high-rise building elevators to design bearings for elevator drive systems used in low- and medium-rise buildings, contributing to further improvement of elevator comfort and safety.
