When a loose or corroded rod end causes play in a steering linkage, robotic arm, or CNC axis, the entire mechanism loses accuracy. Engineers, fabricators, and maker-project builders who need a reliable, corrosion-resistant pivot point turn to PHS female rod end bearings with a threaded shank — a direct-fit solution that eliminates slop and holds alignment under dynamic load.
These PHS-series female rod end bearings feature an A2 stainless steel body and ball, providing solid corrosion resistance in wet or chemically exposed environments. The female-threaded shank accepts a matching bolt or stud for secure attachment. Available in metric thread sizes from M6 to M35 (approximately 0.24 in to 1.38 in), with both right-hand (RH) and left-hand (LH) thread options to suit turnbuckle-style or standard linkage assemblies. Bore diameter and shank length vary by size — see variant options for exact dimensional data.
Typical use cases include: CNC router Z-axis tie rods and anti-backlash linkages; robotic arm pivot joints requiring low-friction articulation; agricultural and industrial machinery control rods where moisture exposure demands stainless construction; and custom suspension or steering linkages on off-road or racing platforms where left-hand thread rod ends enable quick toe adjustment.
Body and ball machined from A2 (304-grade equivalent) stainless steel for reliable corrosion resistance in outdoor, marine-adjacent, and industrial environments.
Both RH and LH thread variants available in each size, enabling turnbuckle-style length adjustment without disassembly — ideal for steering and suspension tie rods.
Covers light-duty M6 linkages through heavy M35 industrial pivots, letting you match the rod end to your load rating and bolt pattern in a single product family.
Internal thread accepts a standard bolt or stud, simplifying installation in tight spaces where a male-shank rod end cannot be threaded into a clevis or bracket.
The spherical inner race allows angular misalignment compensation, absorbing minor shaft deflection and reducing binding in dynamic pivot applications.
Available in 1 Pcs or 2 Pcs per order, so you can source exactly what your build requires — whether a single replacement or a matched pair for opposing linkage ends.

Match the thread size (M6–M35) to the bolt or stud diameter used in your linkage. For example, if your clevis bracket uses an M10 bolt, select the M10 variant. When in doubt, measure the existing rod end shank thread with a thread gauge or caliper before ordering.
Left-hand thread rod ends are used on one end of a turnbuckle-style linkage so that rotating the central tube simultaneously tightens both ends — allowing length adjustment without removing either rod end. If your assembly does not use a turnbuckle, right-hand thread is the standard choice.
Yes. The A2 stainless steel body and ball provide solid corrosion resistance for outdoor, marine-adjacent, and light chemical exposure environments. For highly aggressive chemical or saltwater immersion applications, verify compatibility with your specific conditions before use.
Dynamic and static load ratings vary by thread size — larger sizes (M25–M35) carry significantly higher loads than smaller sizes (M6–M10). Contact us to confirm the rated dynamic radial load for your specific size before use in safety-critical applications.
Yes. PHS female rod end bearings are widely used in CNC tie rods, anti-backlash linkages, and robotic arm pivot joints. The spherical ball joint compensates for minor angular misalignment, reducing binding and extending service life in dynamic, repetitive-motion applications.
No special tools are required. Thread the rod end onto a matching bolt or stud by hand, then tighten with a standard open-end or combination wrench sized to the hex flats on the shank. Use a jam nut on the shank threads to lock the rod end at the desired position and prevent loosening under vibration.
PHS rod ends have a standard-length shank, while PHSA variants typically feature a shorter shank for space-constrained installations. Both use the same female-thread and spherical-ball design. This listing covers the PHS (standard shank) series.
