Bore 14 / M14 X 2.0 ThreadSA14TK SAL14TK 14 M14 X 2.0 Carbon Steel Male Rod End (Metric)
SA SI Product Overview
SA14TK / SAL14TK is a three-piece metric self-lubricating male rod end with a 14 mm bore (B) and 36.00 mm body housing diameter (D). A 52100 steel ball — precision ground, heat treated, and hard chrome plated — runs in a copper alloy race lined with PTFE for consistent, maintenance-free articulation. Body length (AM) is 60 mm, thread shank engagement (CM) is 38 mm, body width (W) is 19 mm, body thickness (T) is 13.50 mm. Approximate weight: 129 g.
Rated at 41.9 kN static radial load with ±13° misalignment angle, this M14 X 2.0 threaded male rod end suits industrial machinery, agricultural equipment, and moderate-to-heavy linkage systems. The copper alloy PTFE-lined race distinguishes the SA-TK series from nylon-race designs, offering better dimensional stability and a metal-like feel with self-lubricating properties. Carbon steel body with silver zinc plating.
Available in right-hand (SA14TK) and left-hand (SAL14TK) metric thread configurations. Studded version (add ‘-S’ suffix, e.g., SA14TK-S) also available. Yellow zinc plating option available. Inch-thread equivalent is the VM series.

SA SI Frequently Asked Questions
What is the difference between SA-TK and SI-TK rod ends?
SA-TK parts are male-thread rod ends and SI-TK parts are female-thread rod ends. Both belong to the same 3-piece self-lubricating metric series and share the same core material direction.
What materials are used in the SA-TK SI-TK series?
This series uses a hard-chrome-plated 52100 bearing steel ball, a copper alloy race with PTFE lining, and a carbon steel body with silver zinc plating.
Is the SA-TK SI-TK series self-lubricating?
Yes. The PTFE-lined copper alloy race provides self-lubricating articulation for metric linkage systems that need smoother movement and reduced maintenance.
Are studded versions available in the SA-TK SI-TK series?
Yes. Studded configurations are available by adding S to the suffix, for example SA12TK-S, depending on the exact size and build requirement.
Is there an inch-size equivalent for this series?
Yes. The inch-size equivalent referenced in the source specification is the VM VF series, which can be reviewed when inch-thread compatibility is required.
What applications are best suited to SA-TK SI-TK rod ends?
SA-TK SI-TK rod ends are well suited to agricultural machinery, industrial motion systems, mechanical control assemblies, packaging equipment, and other metric linkages that benefit from a self-lubricating 3-piece design.
