Agricultural gripping conveyor chains: suitable for walking wheat, rice harvester and set-motorized rice and wheat thresher, semi-feeding combine harvester.

Hollow pin chain: transportation, single-pitch, double pitch, pitch. Its attachments or crossbar can be inserted into the chain of any chain section without the need to disassemble the chain.

Timing chain: for the transmission between the engine crankshaft and camshaft. Because of the engine piston stroke and exhaust time with strict requirements, so the chain is called timing chain. This kind chain can be replaced by the roller chain and silent chain. Timing chain is mainly use for the engine (diesel or gasoline) conveyor of the cars, motorcycles and boats drive. In order to reduce the weight of the engine, the chain and engine installation gap is very small, even some did not plated any tensioning device, so it is not only require high precision but also high abrasion resistance.

Chain limitations: As a common transmission power part, and the design of "chain" through the hyperbolic arc, the chain can reduce friction, for use in relatively large power but run more slowly. It is more advantage than the belt drive, such as tanks, pneumatic compressors, etc., but the transmission speed can not too fast, because the chain flexibility is not as good as belt conveyors.
