Continuous motion, stoppage, and accumulation

Free-Flow Conveyor Chain allows continuous motion and free speed control of objects while also providing the ability to stop and/or accumulate conveyed items at a work station or other functional location. Tsubaki manufactures several types of free-flow chain, including Top Roller, Outboard Roller, and Roller Table; and our revolutionary Double Plus Chain, which permits conveyed items to travel 2.5 times faster than the chain drive speed. A variety of features are available within this wide selection, such as electro-conductive plastic rollers to counter static electricity and dust, as well as anti-corrosion and low noise features to suit application requirements in a variety of industries.

double plus chain

Very quiet operation is the main advantage of using Tsubaki's Double Plus Chain. Because materials transported on the chain move 2.5 times faster than the chain itself, motor speeds can be reduced thereby cutting down on noise and costs. Safety is ensured by the extra-large, engineering plastic center rollers which allow for installation of a chain cover.

The original design of Tsubaki's aluminum guide rail is standardized for easy installation.

plastic side roller chain

The construction of our Plastic Side Roller Chain makes for a highly compact conveyor system. This is further enhanced by the chain's capacity to flex backward, requiring minimum space on the return side of the operation. Since a large number of rollers can be installed, a conveyor can easily be made where small objects are placed directly on the chain. Quick starting is also possible by installing high friction brake rollers.

roller table

Line pressure is notably reduced during accumulation because of the low rolling friction coefficient of Roller Table's plastic rollers (µ= 0.06 to 0.10). This low rolling friction coefficient protects conveyed objects from being damaged and enables smooth divergence and confluence on the conveyor. In addition, smooth transfer to the next line is ensured by special attachments between strands that are flush with the rollers.
