Renold - High Performance Transmission Chain

12B2-NO30 Link and a Half - Double Cranked Link 3/4" Pitch Duplex Renold Synergy

Renold Synergy - Strong, Powerful. Even better performance.

Synergy is the only true high-performance chain on the market.

  • Improved fatigue resistance - Plate and connecting link design optimises stress distribution and fatigue performance. Synergy® performs, on average, 30 percent better than other brands under repeated shock loading and continual heavy loads.
  • Better wear resistance - Independent tests show Renold Synergy® performed up to six times better than the highest quality competitor’s chain.
  • Built to perform - Each component of Renold Synergy® is engineered to perfection using cutting-edge design tools such as Finite Element Analysis (FEA). It all adds up to chain performance that exceeds the sum of its parts.
  • Plate Shape - Wide waist profile for improved stress distribution; plate thickness maximised within the constraints of the Standard.
  • Bushes - Solid extruded bush provides improved roundness and strength compared to curled bushes. Profiled ends improve bearing area and extend wear life.
  • Hole Quality - Triple punch holing ensures controlled positional location of pin and bushing for even wear.
  • Interference Fits - Optimised to ensure maximize fatigue life. Fatigue Resistance Pre-stressed surfaces increase fatigue resistance.
  • Wear Resistance - Profiled components and special pin surface coating enhance wear resistance.
  • Connecting Link - Unique in design, allowing for a chain system with no component weaker than another.

Exclusive! Unique end-softened pins cut to length quickly and cleanly using just one tool. Get up and running faster than ever before.

Platinum-coloured connecting links stand out against the black surface plates, so they’re easy to identify and remove. Synergy® lasts longer and resists greater shock loads, making it the most reliable chain on the market.
