CV Ball Joint Cage
Precision Engineering for Reliable Drivetrain Performance
A CV Ball Joint Cage is a vital part of every vehicle’s drivetrain system. It ensures that power from the transmission is transferred smoothly to the wheels, enabling a comfortable, stable and safe driving experience.
At RAS Bearings Pvt. Ltd., we manufacture high-precision CV Joint Cages designed for exceptional torque transmission, reduced vibration and extended durability. Each component is produced with advanced CNC technology, tight tolerances and premium metallurgical consistency making it ideal for front-wheel drive (FWD), rear-wheel drive (RWD) and all-wheel drive (AWD) vehicles.
Function and Role in Vehicle Performance
A Constant Velocity (CV) Joint allows the transmission to deliver consistent rotational speed even as the suspension moves or the wheels turn. The cage inside the CV joint keeps the steel balls evenly spaced, ensuring friction-free movement and seamless torque delivery between the driveshaft and wheel hubs.
By maintaining accurate ball alignment, the cage prevents drivetrain binding, uneven wear and vibration. The result is:
- Smooth cornering without torque loss
- Lower mechanical stress on transmission parts
- Enhanced stability and steering precision
A poorly manufactured cage can cause noise, grease leakage or jerky acceleration all of which compromise vehicle safety and comfort. RAS Bearings eliminates these issues through precision forging and strict process control.

Frequently Asked Questions (FAQs)
What is the function of a CV Ball Joint Cage in a vehicle?
The CV Ball Joint Cage holds and guides the steel balls inside the constant velocity (CV) joint. It ensures smooth torque transfer from the driveshaft to the wheels, maintains correct ball spacing and prevents friction or binding during vehicle movement resulting in stable, vibration-free performance.
Why does the quality of the CV joint cage matter?
A high-quality CV joint cage provides precise ball alignment and correct clearances, reducing vibration, noise and wear. Poorly manufactured cages can cause jerky movement, grease leakage and even steering instability, especially during turning or acceleration.
What materials are used to manufacture RAS Bearings CV Ball Joint Cages?
RAS Bearings manufactures cages from premium alloy steels such as SAE 52100 (100Cr6) and chrome-molybdenum steel, known for strength and fatigue resistance. Each cage undergoes advanced forging and heat treatment (carburizing, nitriding or carbo-nitriding) to enhance surface hardness and durability.
How can I tell if a CV joint or cage is failing?
Common signs include clicking noises while turning, vibration in the steering wheel or uneven acceleration. In severe cases, you might feel stiffness while steering or notice grease leaking near the CV joint area, all indicators that the cage or joint may be worn or damaged.
Are RAS Bearings CV Ball Joint Cages suitable for heavy-duty or off-road applications?
Yes. RAS Bearings designs its CV Ball Joint Cages for high-load and high-torque environments, including trucks, SUVs, agricultural machinery and off-road vehicles. The forged construction and advanced metallurgy make them resistant to dust, shock and extreme temperatures.
Does RAS Bearings offer OEM customization for CV joint cages?
Absolutely. RAS Bearings Pvt. Ltd. provides custom engineering and OEM solutions for clients worldwide. Our R&D team can modify cage geometry, materials and heat treatment specifications based on vehicle type, torque requirements and operating conditions.
