The lubrication method in the chain rail system directly affects its performance, life and applicable scenarios. The main difference between dry chain and Lubricated chain lies in the type of lubricant, maintenance method and applicable environment. The following is a detailed comparison and selection suggestions:
Lubricated chain (wet lubrication):
Use high-viscosity lubricating Lubricated (such as mineral Lubricated or synthetic Lubricated) to form a thicker Lubricated film to cover the chain surface. It is characterized by strong waterproofness and long-lasting lubrication, but it is easy to absorb dust and impurities.
Dry chain (dry/wax lubrication):
Dry chain Lubricated is mainly based on silicon or wax, and a dry protective layer is formed after the solvent evaporates. Wax lubricants (such as paraffin) form a waxy coating, which has both lubrication and dustproof effects.
| Features | Lubricated chain (wet) | Dry chain (dry/waxy) |
| **Waterproofness** | Strong (suitable for humid environments) | Medium (waxy is better than dry) |
| **Dustproofness** | Poor (easy to absorb dust) | Excellent (dry surface and not easy to get dirty) |
| **Lubrication durability** | Long (no need to refill frequently) | Short (regular re-application is required) |
| **Applicable temperature** | -30℃~120℃ (lithium-based grease) | Dry Lubricated has poor high temperature resistance, and waxy is more stable |
Harsh working conditions: such as mines, muddy roads or seawater environments, where waterproof and rust-proofing are required.
High-load transmission: engineering machinery chain rail system, because the Lubricated film can withstand greater pressure and reduce direct friction between metals.
Long maintenance cycle: Suitable for equipment that is difficult to maintain frequently, such as agricultural machinery or heavy trucks.
Clean environment: Riding on paved roads (bicycles/motorcycles) or indoor equipment requires keeping the chain clean.
Competition requirements: Professional riders prefer wax chain Lubricated because it is quiet, low-resistance and reduces transmission loss.
Dust environment: In factory production lines or desert areas, dry chains can avoid increased wear caused by dust adhesion.
Wax lubrication upgrade: High-end wax chain Lubricated (such as KMC GO WAXED) combines lubrication and dust prevention advantages, suitable for users who pursue performance and low maintenance.
Lubricated and gas lubrication: In industrial chain rail systems, waste is reduced through precise Lubricated supply, suitable for high-speed or high-precision equipment.
Cleaning requirements: The sludge needs to be cleaned regularly with diesel or neutral solvents to avoid strong acids and alkalis from damaging the lubrication layer.
Lubricated filling standard: grease injection every 50 hours (shortened to 30 hours in a humid environment), lithium-based grease NLGI 2# is recommended.
First use: The original grease on the chain surface needs to be thoroughly cleaned to ensure that the wax layer or dry Lubricated is fully attached.
Re-coating frequency: Dry Lubricated is re-coated every 100-200 kilometers, and wax Lubricated is maintained every 300-500 kilometers.
Storage protection: Apply waterproof sealing grease (such as Loctite 5773) to prevent rust before long-term disuse.
Rainy/muddy → Lubricated chain (wet); dry/dusty → dry chain (wax).
Difficulty in frequent maintenance → Lubricated chain; pursuit of low maintenance → wax dry chain.
Durability → Lubricated chain; transmission efficiency → wax dry chain.
Example recommendation:
Construction machinery: wet Lubricated chain + monthly deep cleaning.
Road bike: wax dry chain + re-coating every 500 kilometers.
Through the above analysis, users can flexibly choose the lubrication method according to actual needs, and refer to the technical parameters of specific products (such as temperature range, waterproof level) to optimize the service life and efficiency of the chain rail system.
