The "Crescent Top Chain Series" features a unique top plate shape. This top plate design reduces the likelihood of transported items getting stuck in the gaps between the plates, thereby increasing equipment operating rates. Additionally, the minimum turning radius has been reduced compared to conventional products. This allows for smaller sprockets, making it possible to install in tighter spaces. 【Specifications (partial)】 ■ Chain brand: TCS1140 ■ Plate width (W1 [mm]): 114.0 ■ Plate length (L [mm]): 101.0 ■ Roller diameter (φD [mm]): 15.88 ■ Rail groove width (W2min [mm]): 47.0 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "RK Double Pitch Roller Chain Series" that we handle. The large roller series operates smoothly on horizontal and inclined conveyors, as it moves solely through rolling wear, ensuring efficiency and longevity without strain. The rollers extend beyond the plates, allowing them to roll along the rails. Additionally, the small roller series is primarily used for vertical conveyors. 【Lineup】 ■ Small Roller Series ■ Large Roller Series *For more details, please refer to the PDF materials or feel free to contact us.

The "RK Roller Chain Series" offers sufficient wear resistance, fatigue resistance, and impact resistance, resulting in a long lifespan. It allows for flexible design and low maintenance costs, making it a very economical chain that can be used with confidence. Chain transmission has the advantage of precise gear ratios without the slipping associated with belt drives. Unlike gears and belts, it is not constrained by center distance, allowing for multi-axis transmission with a series of chains, enabling the design of free and compact transmission components. 【Features】 ■ No slipping in transmission ■ Maintains high transmission efficiency ■ Withstands shock loads ■ Center distance can be freely adjusted and is compact ■ Initial tension is unnecessary ■ Not affected by the environment *For more details, please refer to the PDF materials or feel free to contact us.
