Overview
The Tsubaki 3202641 roller chain #40 is a precision-engineered, standard riveted chain designed for demanding power transmission applications. This cut-length chain features 29 pitches (approximately 14.5 feet) and meets ANSI standards for mechanical drive systems. Tsubaki chains are engineered for durability, fatigue resistance, and consistent performance in industrial machinery, conveyors, and motion control systems.
Key Features
- Riveted Pin Construction: Heat-treated and shot-peened riveted pins provide superior fatigue strength and impact resistance
- Ring-Coined Connecting Links: Eliminate weak-link failure by providing the same fatigue strength as the base chain
- Pre-Stressed Design: Minimizes initial elongation and reduces troublesome adjustments during startup
- Carbon Steel Material: Corrosion-resistant standard carbon steel suitable for general industrial environments
- ANSI Standard Compliance: Meets industry specification for interchangeability with other #40 standard chains
