2. Small Pitch Conveyor Chains
(3) Low noise: the noise made from engaging the sprockets is 5 to 7 dB lower. (4) In Plastic Sleeve Chain, the maximum allowable tension is one-sixth, and the allowable load of the R-roller is about one-third that of the same-sized all-steel chain (with lubrication).
Sprockets Use the same sprockets as for Double Pitch Roller Chain.
Application Series There are special low-noise engineered plastic R-rollers, which can reduce the noise from the standard engineered plastic type by 7 dB. The allowable roller load for low-noise R-rollers is about 30 percent less than standard engi- neered plastic R-rollers.
