![[Tsubaki] — RS140-SUP-1 Super Chain Heavy-Duty Roller Chain](https://img.prosourcemro.com/2026/05/001-266-300x290.png)
Tsubaki Super Chain — heavy-duty roller chain achieving up to 40% higher maximum allowable load than standard RS roller chain of the same size. Thicker and wider plates with optimized mid-section curvature for compact design without sacrificing strength. Pin fatigue strength approx. 40% higher than standard RS chain. Excellent shock absorption. Can substitute one size down from standard RS chain. Base dimensions (pitch, roller dia, inner link width) identical to RS roller chain. Available in single strand; M-type and F-type connecting links.
