1. Selection Based on Load Type
Light Load, High Speed: Choose toothed chains or silent chains to reduce noise and wear.
Heavy Load, Low Speed: Choose roller chains or plate chains to ensure strength and durability.
2. Selection Based on Working Environment
High-Temperature Environment: Choose high-temperature resistant materials (such as stainless steel chains).
Humid Environment: Choose rust-resistant coated or stainless steel chains.
Dusty Environment: Choose chains with good sealing properties (such as roller chains with sealing rings).
3. Selection Based on Transmission Precision
High-Precision Transmission: Choose toothed chains or synchronous belt chains to ensure accurate transmission ratios.
General Precision: Choose roller chains or plate chains for lower cost.

4. Selection Based on Economy
Low-Cost Requirements: Choose ordinary roller chains.
Long-Life Requirements: Choose high-strength alloy steel chains, although the initial cost is higher, the service life is longer.
5. Selection based on installation space:
Compact space: Select a short-pitch chain (e.g., 08B type roller chain).
Large span space: Select a long-pitch chain (e.g., 24A type roller chain).
