Large size conveyor chain (Bearing Roller Conveyor Chain)
Bearing Roller Conveyor Chain has a unique structure with cylindrical bearing inside the rollers, which reduces chain running resistance, significantly improves roller allowable load, and extends the wear life between the bushing and roller.
This achieves improvements that were difficult to achieve with conventional conveyor chains, such as "higher efficiency," "lower costs," "suppression of stick-slip phenomenon *," and "extended roller and rail life."
In addition to the standard specifications, we also offer dust-resistant specifications, Lube-free specifications, Water Resistant Lube Free Series, etc., so you can choose the model that best suits your needs.
*The chain repeatedly moves and stops even though the drive unit is operating continuously.
We also offer the convenient Screw Lock Link, which allows connection and disconnection with just a torque wrench.Learn more.
