When a loose or worn rod end causes slop in your steering linkage, suspension, or actuator arm, the entire mechanism loses accuracy — a frustrating problem for engineers, fabricators, and DIY builders alike. The M6 Female Thread Rod End Bearing SI6T/K is designed for builders who need a compact, reliable spherical joint that handles misalignment without binding, available in both right-hand (SI6T/K) and left-hand (SIL6T/K) thread configurations.
Each bearing features a female M6 threaded shank paired with a 6mm bore spherical inner ring, typically measuring 6mm bore × 19mm outer diameter × 10mm body width (dimensions may vary slightly by variant — see variant options for confirmed specs). The body is constructed from carbon steel with a zinc-plated or chrome finish for corrosion resistance, while the inner ball is hardened steel for long service life.
These rod end bearings are well-suited for RC vehicle steering linkages requiring precise toe adjustment, CNC router Z-axis and gantry pivot connections, industrial actuator and cylinder clevis joints, and custom suspension geometry on go-karts or lightweight off-road builds.
Available in SI6T/K (right hand) and SIL6T/K (left hand) to suit opposing-thread turnbuckle setups and symmetric linkage pairs.
The 6mm bore accepts standard 6mm pivot pins and bolts, while the spherical design allows angular misalignment compensation without binding.
Hardened steel ball and carbon steel body with zinc-plated or chrome finish resist corrosion and wear in demanding mechanical environments.
The female M6 thread shank threads directly onto M6 rods or studs, enabling quick installation and precise length adjustment without special tooling.
Available in packs of 1, 5, 10, 20, or 30 pieces — order exactly what your project requires, from single replacements to bulk workshop stock.
The spherical joint accommodates angular misalignment typically up to ±15°, reducing stress on connected rods and extending the life of the entire linkage assembly.

Right-hand thread (SI6T/K) tightens clockwise and is the standard for most applications. Left-hand thread (SIL6T/K) tightens counter-clockwise and is used on the opposing end of turnbuckle assemblies or symmetric linkage pairs where both ends must be adjusted simultaneously by rotating the center rod. If you are replacing an existing rod end, check the thread direction on the original part before ordering.
The inner bore is 6mm, designed to accept a 6mm pivot pin, bolt, or shaft. This is a metric M6 bore — ensure your pivot hardware matches this diameter for a proper fit.
The carbon steel body features a zinc-plated or chrome finish that provides moderate corrosion resistance for general mechanical use. For prolonged outdoor exposure or wet environments, periodic lubrication and inspection are recommended. For highly corrosive environments, consider stainless steel rod ends instead.
The spherical inner ring typically accommodates angular misalignment up to approximately ±15°. Exceeding this range can cause edge loading on the ball, accelerating wear. Always design your linkage geometry to keep operating angles within this limit for optimal service life.
Yes. M6 female thread rod end bearings are commonly used in CNC router gantry pivots, Z-axis lead screw supports, and robotic arm linkages where a compact spherical joint is needed to accommodate slight misalignment between connected components. The female thread shank allows direct connection to M6 threaded rods without additional adapters.
Most linkage assemblies use rod ends in pairs — one right-hand and one left-hand per turnbuckle rod. For a single-axis steering or suspension setup, a pack of 2 (one of each thread direction) is typical. For multi-axis CNC builds or bulk workshop stock, packs of 10, 20, or 30 offer better per-unit value. Select your quantity and thread direction using the variant options above.
The shank follows the standard metric M6 thread pitch (1.0mm pitch), conforming to DIN ISO 12240-4 SI series specifications. This ensures compatibility with standard M6 threaded rods, turnbuckles, and clevis hardware available from most hardware and engineering suppliers.
