Durable TCC-IV Long Travel Constant Contact Side Bearings from China Factory: Top Suppliers for High-Speed Applications
Basic Information
The characteristic of the constant contact side bearing is its unique metal to metal design, which can provide more stable operating performance by instantly counteracting the rolling vibration of the bogie. This design can weaken the friction and energy of the bogie before its vibration affects vehicle stability and causes component wear.
