CV Joint Balls

KOK supplies CV joint balls for aftermarket and rebuilder applications.

CV joint balls are precision spherical rolling elements used in ball-type CV joints to transmit torque while allowing angular movement.

Product Scope

KOK supplies CV joint balls in defined diameters and tolerances suitable for common ball-type CV joint configurations. These components are supplied as individual rolling elements, not as complete joint assemblies.

Design Characteristics

CV joint balls supplied by KOK feature:

• Precision spherical geometry
• Tight diameter tolerances
• Hardened steel construction for fatigue and wear resistance

Uniformity across all balls in a joint set is essential for proper load sharing.

Materials & Manufacturing

CV joint balls are manufactured from bearing-grade hardened steel.

Production focuses on:

• Sphericity and surface finish
• Dimensional consistency
• Batch-to-batch repeatability

Application Scope

• Ball-type CV joint rebuilding
• Automotive driveline repair
• Powersports and light vehicle applications
