Рекомендации по установке (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
Способ установки: 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 / суровые условия

Типичные применения

Automatic constant tensioning for roller chains, timing belts and flat belts

Конвейеры, упаковочное оборудование, деревообработка, glass equipment, автоматизированные производственные линии

Scraper compression, idler roller floating support and low-stroke vibration damping

Поиск неисправностей

Rubber cracking / ageing: Перегрев, 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
Шум / chain jumping: Mounted on the tight side, preload angle exceeded, or large sprocket misalignment

Примечания по замене

Внутренний эквивалент: 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 Table for ROSTA SE 18 (06 011 003) Compatible N-Type Tension Sprockets

Selection Constraints (Критический)

Upper chain limit: SE18 not recommended for chain larger than 60 (12Б) один ряд; 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
Материал: 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

Отверстие: 10 мм

Несущий: 6200ЗЗ

Tooth profile: ИСО 8187 (ОТ), avoid non-standard American tooth forms which cause jumping teeth

Общая ширина: Must not interfere with SE18 tension arm side plates

Tightening Torque for SE18 Central Bolt

M10 Class 8.8: 49 Нм (tensioner body fixing bolt)

Руководство по быстрому выбору

06Б / 35 → N3/8-10S

08Б / 40 → N1/2-12S (SE18 preferred)

10Б / 50 → N5/8-12S

12Б / 60 → N3/4-12S (верхний предел, careful application)

No meshing required, press chain plate → RL15/18 smooth roller

Quick Selection Notes
Same numeric size (например. SE18 / SE18-G / SE18-W): identical outline and mounting hole geometry, only rubber compound and coating differ; прямая взаимозаменяемость
SE-W high-temperature version has 40% reduced tension; select one size up during design
SE-I stainless steel: Более высокая стоимость, same force rating as standard, еда & pharma use
SE-R reinforced arm: For shock loads; not recommended for normal chain conveyors due to premium cost
SE-F flange version: Different mounting interface; cannot directly replace center-thread SE standard units
Other ROSTA Elastic Units (Not SE series, easy to confuse)

ДР, АБ, AD-P, АС-П, МБ, СТ, DK series. These are swing supports, vibration isolators and motor mounts, not automatic chain / belt tensioners. Do not mix up with SE series.
