إرشادات التثبيت (Chain Drives Recommended)
- Mount on the slack side of the chain, close to the small sprocket: increases wrap angle, suppresses polygon effect and prevents jumping teeth
- Position the swing arm roughly parallel to the chain; recommended preload angle ≤20°, preload force ≤50% of rated value
- طريقة التثبيت: Central M10 bolt friction locking. To set preload: loosen the flange, rotate the housing with a wrench to set preload, then retighten the central bolt
- Mounting surface must be flat and rigid; optional pin anti-rotation in flange slot for dusty / البيئات القاسية

استكشاف الأخطاء وإصلاحها
- Rubber cracking / ageing: الإفراط في درجة الحرارة, oil attack or long-term operation at maximum deflection; prefer SE-G oil-resistant variant
- Tension decay: Rubber fatigue. The ROSTA rubber insert cannot be replaced separately; replace the complete unit
- ضوضاء / chain jumping: Mounted on the tight side, preload angle exceeded, or large sprocket misalignment
ملاحظات الاستبدال
ما يعادلها المحلية: Multiple domestic rubber torsion tensioners marked SE18. Verify J1/J2 force rating, central M10 thread and overall dimensions. Rubber compound determines temperature and oil resistance.

Selection Constraints (شديد الأهمية)
- Upper chain limit: SE18 not recommended for chain larger than 60 (12ب) صف واحد; 80 / 16B chain requires upgrade to SE27
- Preload angle: Max recommended deflection ≤20°, preload force ≤50% rating (≤175 N) to prevent premature rubber ageing
- Mounting pin: SE18 arm pin diameter d=10 mm; sprocket bore 10 mm with bearing, fit directly to arm hole and lock with M10 nut
- Velocity limit: N sprocket max linear velocity ≤2.5 m/s; select SE27 above this speed
- مادة: Standard N sprocket C45 hardened steel; stainless steel sprockets available for food / wet service; RL rollers are black wear-resistant polyurethane
Domestic Equivalent Matching Requirements for Idler Sprockets
تتحمل: 10 مم
تحمل: 6200ZZ
Tooth profile: ايزو 8187 (من), avoid non-standard American tooth forms which cause jumping teeth
Overall width: Must not interfere with SE18 tension arm side plates
