SEDIS – Alpha Premium Range Brochure

Design intent
Alpha Premium transmission chains raise endurance under shock loads and reversing duty by optimizing pin/bush metallurgy, plate profiles and manufacturing tolerances.

Performance levers

• Enhanced case‑depth on pins and bushings to resist brinelling under boundary lubrication.
• Controlled plate geometry to distribute stress at the waist and rivet holes, delaying fatigue crack initiation.
• Pre‑stretching and proof loading to stabilize early elongation and improve indexing repeatability.

Application domains

• Machine tools, packaging actuators, indexers and moderate‑speed drives exposed to shock.
• Retrofits where chain pitch stability directly affects repeatability and scrap rate.

Specification checklist

1. Duty profile (continuous/indexing, reversing, peak torque) and target life in cycles.
2. Environmental loads (abrasives, temperature, moisture) and lubrication method.
3. Attachment needs, master link type and take‑up travel available.
