1-1/4 Spherical Bearing 2-3/8 OD PTFE Coated

The 1-1/4 spherical bearing 2-3/8 OD PTFE coated from FK Rod Ends is a precision suspension component engineered for high-performance vehicle builds, competition suspension tuning, and advanced chassis geometry work. This bearing serves as a critical junction point in control arms, A-arms, and tie-rod assemblies where pivoting motion and load transfer demand low friction and angular compliance. Whether you're building a dedicated road-race platform, upgrading a street-performance suspension, or restoring a vintage muscle car with modern handling characteristics, this spherical bearing eliminates bind and allows smooth articulation through suspension travel.

Featuring a 1-1/4 inch bore diameter with a 2-3/8 inch outside diameter, this bearing delivers a robust load-carrying capacity in a compact envelope suitable for tight packaging constraints. The PTFE (polytetrafluoroethylene) coating provides a dry-running, self-lubricating surface that eliminates the need for grease packing while reducing maintenance in high-deflection suspension geometries. The spherical design allows multi-directional articulation, accommodating both radial and angular loads while maintaining consistent friction characteristics across the full range of motion—critical when fine-tuning anti-squat, anti-dive, and roll center geometry on independent suspension systems.

Fabricators, suspension engineers, and serious enthusiasts benefit most from this bearing's combination of durability and precision. It's commonly paired with adjustable control arms in coilover builds, double-wishbone conversions, and race-derived suspension kits where eliminating play directly translates to improved steering response and predictable weight transfer. The PTFE coating makes it ideal for applications where water ingress or salt exposure occurs, and the compact 0.89 lb weight keeps unsprung mass minimal—a meaningful advantage in performance vehicles where every fraction of a pound at the wheel improves acceleration and braking feel.
