Bore 20 / M20 X 1.5 ThreadJMR20M / JML20Mは、メートルねじのオス式精密ロッドエンド（3分割式）で、内径 20 mm（B）、本体ハウジング径 46 mm（D）。34.93 mm 52100鋼ボールは精密研削・熱処理・硬クロムめっき済みで、PTFEライナーオプション付き合金鋼精密軌道輪に収められています。本体長（AM）= 78 mm、ねじシャンクかみ込み（CM）= 47 mm、本体幅（W）= 25 mm、本体厚（T）= 18.0 mm。参考重量：290 g。
静的ラジアル荷重 50,952 N、心ずれ角 ±20°で定格されますが、このM20 X 1.5ねじ付きオスロッドエンドは、ヘビーデューティ産業機械、農業機具、大型アクチュエーターシステムに適しています。3分割式精密構造により2分割式よりも厳密な寸法制御が可能で、変動する負荷サイクル下でも安定した可動が求められる用途にとってJM-Mシリーズは実用的なステップアップとなります。イエロークロメートめっきを施した炭素鋼本体です。
右ねじ（JMR20M）および左ねじ（JML20M）のメートルねじ構成が選択可能です。自己潤滑・給油不要動作用のPTFEライニング版（「T」接尾辞を追加、例：JMR20MT）もございます。スタッド付き版（「S」接尾辞を追加）もございます。別ぴッチのねじ版は要望に応じて対応します。銀色ユニクロめっきも選択可能。インチねじ相当品はJMシリーズです。

The JMR20M / JML20M is a three-piece precision metric male rod end with 20 mm bore and M20 X 1.5 thread, built for very heavy-duty structural linkages, large industrial machinery, and high-load pivot assemblies.
Bore (B) is 20 mm, body housing diameter (D) is 46 mm, body length (AM) is 78 mm, thread shank engagement (CM) is 47 mm, body width (W) is 25 mm, and body thickness (T) is 18.0 mm. Approximate weight is 290 g.
The JMR20M is rated at 50,952 N static radial load with ±20° misalignment angle.
The 34.93 mm ball is 52100 bearing steel, precision ground, heat treated, hard chrome plated, seated in an alloy steel precision race with a PTFE liner option. The body is carbon steel, yellow zinc plated.
JMR20M is the right-hand thread version and JML20M is the left-hand thread version of the same 20 mm male rod end — order the pair to match your linkage's thread-hand requirements.
Yes — add a 'T' suffix (e.g., JMR20MT) for a PTFE-lined, maintenance-free version; a studded version is available by adding an 'S' suffix; alternate thread pitch variants and silver zinc plating are available on request; the inch-thread equivalent is the JM series.
