Durable TCC-IV Long Travel Constant Contact Side Bearings from China Suppliers and Factory 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.

Our Advantages
Introducing our TCC-IV long travel constant contact side bearings, designed for the rigorous demands of high speed, high mileage applications. The robust and heat-resistant design of these side bearings maximizes their service life and ensures peak performance even under the most demanding conditions.
One of the key features of our constant contact side bearings is their unique metal-to-metal design. This design allows them to immediately counteract bogie rolling vibrations, thereby enhancing stability during operation. By mitigating friction and energy before they impact vehicle stability and cause component wear, our side bearings provide a more reliable and efficient solution. Our TCC-IV long travel bearings have a side bearing height of 5.95 inches (151 mm) and meet vertical stiffness requirements.
Frequently Asked Questions
What is the primary advantage of the metal-to-metal design in TCC-IV side bearings?
The unique metal-to-metal design provides superior stability by instantly counteracting bogie rolling vibrations, reducing energy and friction before they impact vehicle performance.
What is the standard height for these constant contact side bearings?
The standard side bearing height is 5.95 inches (151mm) with a tolerance of ±1/8 inch.
Do these side bearings comply with industry standards?
Yes, the manufacturing and processing of these side bearings meet all relevant requirements of the AAR M-948 specification.
What load capacities are available for the TCC-IV LT series?
We offer four capacity variants: 3000 lbs (30-LT), 4500 lbs (45-LT), 6000 lbs (60-LT), and 8000 lbs (80-LT).
What applications are these bearings best suited for?
They are specifically designed for high-speed and high-mileage applications where heat resistance and long service life are critical.
How do these bearings prevent component wear?
By weakening the friction and energy of the bogie vibrations immediately, the bearings prevent those forces from causing excessive wear on vehicle components.
