Questa convenzione \u00e8 diversa da quella delle ruote dentate europee DIN 8187 e americane ANSI B29.1, dove la sede della chiavetta \u00e8 tipicamente posizionata tra i denti.

Questo controllo visivo \u00e8 particolarmente utile durante l'installazione di ruote dentate di grandi dimensioni, dove la misurazione della posizione della ruota dentata risulta difficoltosa.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fff; border-radius: 6px; padding: 18px 16px; border-left: 4px solid #e8a020; box-shadow: 0 1px 4px rgba(13,27,46,0.07);\">\n<p style=\"font-size: 14px; font-weight: bold; color: #0d1b2e; margin: 0 0 8px;\">\u26a0\ufe0f Non sostituire il pignone europeo\/ANSI<\/p>\n<p style=\"font-size: 12.5px; color: #334155; line-height: 1.65; margin: 0;\">Un pignone europeo o ANSI non pu\u00f2 essere sostituito con un pignone standard asiatico su una catena asiatica, anche se il passo e il foro sono gli stessi. Il profilo del dente (raggio della curva di appoggio, larghezza del dente e angolo del dente) differisce tra i vari standard. L'utilizzo di una catena e di un pignone non compatibili causa un innesto inadeguato dei rulli, un'usura accelerata e la rottura prematura del pignone entro poche settimane dall'installazione.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fff; border-radius: 6px; padding: 18px 16px; border-left: 4px solid #64748b; box-shadow: 0 1px 4px rgba(13,27,46,0.07);\">\n<p style=\"font-size: 14px; font-weight: bold; color: #0d1b2e; margin: 0 0 8px;\">\ud83d\udcd0 Standard JIS B1301 per scanalature<\/p>\n<p style=\"font-size: 12.5px; color: #334155; line-height: 1.65; margin: 0;\">Le dimensioni della sede della chiavetta sono conformi alla norma JIS B1301 (rivista nel 1976), lo standard giapponese per chiavette e sedi di chiavetta parallele in fori metrici. Questa norma \u00e8 dimensionalmente simile alla DIN 6885, ma utilizza proporzioni di profondit\u00e0 leggermente diverse per fori di piccole dimensioni (inferiori a 22 mm). Utilizzare sempre una chiavetta JIS B1301 o DIN 6885 nelle ruote dentate standard asiatiche; non utilizzare chiavette ASME B17.1 in pollici, che presentano rapporti larghezza\/profondit\u00e0 diversi.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- \u2550\u2550 SPEC TABLE \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 --><\/p>\n<div style=\"background: #f4f7fb;

This is a different convention from European DIN 8187 and American ANSI B29.1 sprockets, where the keyway is typically positioned between teeth. The difference matters for two reasons:<\/p>\r\n\r\n<div style=\"display: flex;flex-wrap: wrap;gap: 16px\">\r\n<div style=\"flex: 1 1 240px;background: #fff;border-radius: 6px;padding: 18px 16px;border-left: 4px solid #1a6db5\">\r\n<p style=\"font-size: 14px;font-weight: bold;color: #0d1b2e;margin: 0 0 8px\">\u2714 Visual Installation Confirmation<\/p>\r\n<p style=\"font-size: 12.5px;color: #334155;line-height: 1.65;margin: 0\">With the keyway on the tooth centreline, the engineer can confirm correct installation position by looking at the top of the installed sprocket \u2014 the tooth directly above the key should be centred over the keyway mark on the shaft. This visual check is particularly useful during installation of large sprockets where gauging the sprocket position is difficult.<\/p>\r\n\r\n<\/div>\r\n<div style=\"flex: 1 1 240px;background: #fff;border-radius: 6px;padding: 18px 16px;border-left: 4px solid #e8a020\">\r\n<p style=\"font-size: 14px;font-weight: bold;color: #0d1b2e;margin: 0 0 8px\">\u26a0\ufe0f Do Not Substitute European\/ANSI Sprocket<\/p>\r\n<p style=\"font-size: 12.5px;color: #334155;line-height: 1.65;margin: 0\">A European or ANSI sprocket cannot be substituted for an Asian standard sprocket on Asian chain, even if the pitch and bore are the same. The tooth profile \u2014 seating curve radius, tooth width and tooth angle \u2014 differs between standards. Running mismatched chain and sprocket causes poor roller engagement, accelerated wear and premature sprocket failure within weeks of installation.<\/p>\r\n\r\n<\/div>\r\n<div style=\"flex: 1 1 240px;background: #fff;border-radius: 6px;padding: 18px 16px;border-left: 4px solid #64748b\">\r\n<p style=\"font-size: 14px;font-weight: bold;color: #0d1b2e;margin: 0 0 8px\">\ud83d\udcd0 JIS B1301 Keyway Standard<\/p>\r\n<p style=\"font-size: 12.5px;color: #334155;line-height: 1.65;margin: 0\">Keyway dimensions conform to JIS B1301 (revised 1976) \u2014 the Japanese standard for parallel keys and keyways in metric bore sizes. This is dimensionally close to DIN 6885 but uses slightly different depth proportions for small bore sizes (below 22 mm). Always use a JIS B1301 or DIN 6885 key in Asian standard sprockets \u2014 do not use ASME B17.1 inch keys, which have different width-to-depth ratios.<\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<!--

The seating curve radius and tooth width differ from DIN 8187 and ANSI B29.1 because the Asian standard roller diameter is slightly different from both.

The bore is machined before the heat treatment cycle and confirmed dimensionally after hardening. 25B sprockets are lighter duty \u2014 plain C45 without tooth hardening, suitable for the light loads in 25B drive applications. SUS304 stainless variants (SUSFBP prefix) are plain bore only and are unhardened by material.<\/p>\r\n\r\n<\/div>\r\n<div style=\"border-left: 4px solid #e8a020;padding: 18px 16px;border-radius: 4px\">\r\n<h3 style=\"color: #e8a020;font-size: clamp(13px,1.5vw,15px);margin: 0 0 8px;font-weight: bold\">FBK Flange Type \u2014 Lateral Retention<\/h3>\r\n<p style=\"color: #a8bdd4;font-size: clamp(12px,1.4vw,13px);line-height: 1.65;margin: 0\">The FBK type adds a flange face to the hub, providing a bearing face against a shaft shoulder or collar. This is required in applications where the sprocket must be retained axially on the shaft by its own geometry rather than relying entirely on the setscrew. FBK is the standard type for chain drives in Japanese agricultural machinery and material handling equipment where the sprocket position is located by a shaft step rather than by a setscrew alone.<\/p>\r\n\r\n<\/div>\r\n<div style=\"border-left: 4px solid #e8a020;padding: 18px 16px;border-radius: 4px\">\r\n<h3 style=\"color: #e8a020;font-size: clamp(13px,1.5vw,15px);margin: 0 0 8px;font-weight: bold\">Korea Ever-Power for Asian OEM Drives<\/h3>\r\n<p style=\"color: #a8bdd4;font-size: clamp(12px,1.4vw,13px);line-height: 1.65;margin: 0\">Korean industrial machinery uses JIS-based chain standards for all domestic drives.
