弯板滚子链结构特点：

        链板是弯曲的，无内外链节之分，因而能以一个节距长为单位来接长与缩短链条。磨损后链节节距仍均匀，抗冲击性能好。销轴、套筒和链板间的间隙较大，对链轮的共面性要求较低，销轴容易拆装，便于维修。

Structure features:

The chain plate is curved, without the inner and outer link points, so it can take a long pitch as a unit to take long and shorten the chain. After wearing the chain pitch is uniform, good anti impact performance. The gap between the pin axis, the sleeve and the chain plate is larger, the coplanar requirements of the sprocket are lower, the pin axis is easy to assemble and easy for maintenance..
