![[Tsubaki] — RS40-SNS-1 Low-Noise Chain Roller Chain](https://img.prosourcemro.com/2026/05/001-270-300x300.png)
Tsubaki Low-Noise Chain (SNS) — roller chain with Tsubaki's unique spring roller structure. When the chain engages the sprocket, the spring roller deforms and absorbs collision energy, reducing impact between chain and sprocket teeth. Noise reduction of 6~8 dB vs standard RS roller chain (pre-lubricated, internal test data). SNS variants include unit link and offset link; JL connecting links available separately.
