Variable speed chain conveyor chain
Variable speed chains are categorized by speed (single-speed, 2.5x speed, and 3x speed), material (plastic, nylon, steel, stainless steel), and structure (roller chain, plate chain, gear chain). Key parameters include pitch (12.7mm to 50.8mm), roller diameter (8.51mm to 38.00mm), link plate height (11.8mm to 24.00mm), and tensile strength (18.0kN to 72.8kN). These chains are widely used in conveying systems for different load capacities and environmental conditions.

Types and Parameters of Variable Speed Chain
I. Types of Variable Speed Chains
- By Speed Classification
- Single-Speed Chain: The movement speed of the chain and the pallets is the same.
- 2.5-Times Speed Chain: The movement speed of the pallets is 2.5 times the speed of the chain.
- 3-Times Speed Chain: The movement speed of the pallets is 3 times the speed of the chain.
- By Material Classification
- Plastic Roller Chain: Suitable for light loads and small products, with lower cost.
- Nylon Roller Chain: Suitable for light to medium loads.
- Steel Roller Chain: Suitable for heavy loads and high strength requirements.
- Stainless Steel Roller Chain: Suitable for humid or chemically corrosive environments.
- By Structure Classification
- Roller Chain: Composed of inner and outer links, rollers, pins, etc., suitable for high-speed, heavy-load transmission systems.
- Plate Chain: Made of flat plates forming chain links, suitable for conveying equipment.
- Gear Chain: Equipped with gears on the chain plates, suitable for applications requiring precise power transmission.
