HOME > Technical Guide > Anomalies & Countermeasures
| Phenomenon | Cause | Countermeasures |
|---|---|---|
| Wear to the inside of the link plate or one side of sprocket teeth | Sprocket Alignment Failure | Remove chain and repair sprocket centering |
| Chain is pressed sideway | Use the guide roller and shoe to remove the cause of the press | |
| Vibration of sprocket | Replace with a new sprocket | |
| Roller Rotation Failure | Excessive load on roller | Lubricate between the bush and roller. Selection of proper specifications (GT bearing, roller etc.) |
| Foreign substances enter the bush roller | Protect the chain with partitions, Select wider specifications for bush-roller space | |
| Foreign substances accumulate on the rail | Protect chains with partitions | |
| Bush-roller lubricant sticks to the rail or the roller surface | Use proper lubrication and adjust lubricating method accordingly | |
| Rust accumulation on bush or roller | Use proper lubrication and adjust lubricating method accordingly | |
| Bending Failure | Rust | Please consult with us if you want to protect the chain with partitions. |
| Foreign substances enter between pins and bushes or link plate. | Protect the chain with partitions or pin bushes Make it a specification with a large gap between plates | |
| Chain rides on a sprocket. | Excessive Chain Sag | Reduce slack in chain or insert tightener |
| Sprocket Wear | Replace with new chains | |
| Chain curls in to the sprocket or fail to move | Chain and sprocket aren’t compatible | Replace either chain or sprocket |
| Excessive overload | Reduce the load (fit with shock absorbers etc.) | |
| Chain is worn out and stretched | Replace with new chains | |
| Occurrence of chain "stick slip" surge | Speed is too slow | Adjust to higher speed |
| Other |
Improve frame rigidity or choose a higher grade of chain Select drive rollers with anti-surging specifications |
|
| Abrasion of sprocket tooth base and tooth pressing surface | Insufficient sprocket teeth | Increase the number of teeth in a sprocket |
| Others | Use hardened sprockets or tooth replacement sprockets | |
| Abrasion of plate holes and pins | Excessive tension | Mounting a piece to a sprocket Lubricate both sides of the chain and sprocket. |
| Noise | Insufficient lubrication between bush and roller |
Lubricate sufficiently Use bearing rollers and/or plastic rollers |
| Insufficient lubrication between the parts of sliding in pins and bushes. | Properly lubricate target area | |
| Collision between roller and sprocket | Lubricate Uses resin roller the sprocket section sufficiently. Uses resin roller |
