When a fixed pivot simply won't do — when your linkage must articulate freely under load without binding or wearing prematurely — engineers and makers reach for SQ ball joint rod end bearings. Whether you're building a custom suspension system, a CNC axis linkage, a robotic arm joint, or an industrial control rod, the wrong bearing means play, noise, and early failure. These SQ male-female thread rod end bearings are engineered for builders who need precise, low-friction articulation they can count on.
Each SQ rod end bearing features a forged steel housing with an integrated spherical plain bearing insert, available in right-hand thread sizes from M5 (5 mm / ~0.197 in) through M22 (22 mm / ~0.866 in). The male shank threads into your rod or clevis, while the female bore accepts a pin or bolt to complete the joint. Thread pitch follows standard metric coarse specifications per size (e.g., M5×0.8, M6×1.0, M8×1.25, M10×1.5, M12×1.75, M14×1.5, M16×1.5, M18×1.5, M20×1.5, M22×1.5).
Typical use cases include automotive steering tie-rod replacements and custom suspension linkages, CNC machine axis rod-end connections for linear motion control, and robotic arm joints requiring multi-axis articulation in compact spaces — all scenarios where the long-tail search term "metric right-hand thread rod end bearing" leads builders directly to this component.
The integrated spherical plain bearing allows angular misalignment in multiple planes, eliminating binding in non-collinear linkage assemblies.
Ten thread sizes cover light-duty M5 joints up to heavy M22 structural linkages, letting you match the bearing to your actual load requirements.
The male shank threads directly into a rod end or clevis body; the female bore accepts a through-pin or bolt for a clean, compact joint assembly.
The housing is forged rather than cast, delivering higher structural integrity and resistance to shock loads encountered in dynamic linkage applications.
Right-hand thread convention means these rod ends integrate directly with standard metric hardware — no adapters, no special tooling required.
SQ-series dimensions follow widely adopted rod end standards, making these suitable as direct replacements in existing linkage designs without re-engineering mounting points.

Match the thread size to your existing rod or clevis thread. Measure the outer diameter of the male thread on your rod — that diameter in millimeters is your size (e.g., 8 mm outer diameter = M8). Confirm the pitch matches the variant listing (e.g., M8×1.25 mm). When in doubt, use a thread gauge or contact us to confirm before ordering.
Load capacity scales with thread size — larger sizes carry significantly higher static and dynamic radial loads. Specific load ratings vary by size; please refer to the variant detail page or contact us to confirm the rated capacity for your chosen size before use in safety-critical applications.
The forged steel housing provides solid structural performance. For outdoor or high-humidity environments, we recommend periodic lubrication and, where possible, protective coatings or stainless alternatives. Contact us to confirm the surface finish available for your selected size if corrosion resistance is a primary requirement.
Yes. The SQ series uses standard metric right-hand thread dimensions, so they thread directly onto metric-threaded rods and into standard clevis bodies without adapters. Always verify thread pitch matches your hardware — for example, M14 and M16 in this series use a 1.5 mm pitch rather than the coarse standard, so confirm before assembly.
Yes. The spherical plain bearing insert is designed for oscillating and misalignment motion — not continuous high-speed rotation. They are ideal for control rods, steering linkages, suspension arms, and robotic joints where the bearing rocks or pivots rather than spins continuously at high RPM.
This listing covers right-hand thread (RH) variants only. If you need left-hand thread (LH) rod ends for a turnbuckle-style assembly, please search our store for the LH equivalent or contact us — we can advise on availability.
Thread the male shank into your rod or clevis body to the required engagement depth (minimum 1× thread diameter of engagement recommended). Insert a through-pin or bolt through the female bore and secure with a nut and washer. Ensure the joint can articulate freely through its full range of motion before final torquing. Apply a small amount of grease to the spherical insert if the application involves frequent oscillation.
