1/2 Spherical Bearing w/PTFE Liner

The 1/2 spherical bearing with PTFE liner from FK ROD ENDS is a precision suspension and drivetrain component engineered for high-performance automotive builds where articulation and load distribution are critical. Whether you're fabricating custom control arms, building a competition off-road rig, or upgrading a drift car's steering geometry, this spherical bearing eliminates bind and flex while maintaining smooth rotational freedom across extreme angles. Designed for the dedicated mechanic and fabricator who demands reliability under demanding conditions, this bearing serves as a foundational upgrade for any chassis or suspension system requiring uniball quality without compromise.

The FK ROD ENDS COM8T features a 1/2-inch bore diameter paired with a PTFE (polytetrafluoroethylene) liner that provides low-friction articulation and self-lubricating properties. This design eliminates the need for grease fittings in many applications, reducing maintenance intervals while the PTFE material resists wear from high-frequency movement and variable loading angles. The spherical geometry allows ±45-degree articulation in multiple planes, accommodating the complex motion found in modern suspension kinematics—whether in camber plates, tie-rod ends, or custom fabrication work. The compact 1-inch overall dimension and light 0.07-pound weight make it ideal for weight-conscious builds without sacrificing structural integrity or load capacity.

This bearing is essential for suspension tuners, fabricators, and enthusiasts building adjustable control arms, anti-roll bar links, or custom steering components on street performance cars, track builds, and off-road vehicles. The PTFE liner is especially valuable in sealed environments or high-vibration applications where traditional rod ends may require frequent maintenance. Installation requires basic mechanical knowledge and proper tooling to press or bolt into your custom bracket or OEM-compatible housing—verify bore diameter and thread orientation before ordering to ensure fitment with your suspension design. Pair with matching rod end spheres and clevis blocks from the FK lineup for a complete, harmonized suspension system.
