Chains for rotary tables (arc chains)
The arc imposes certain specific requirements on the chain. Standard-compliant chains do not bend to a relatively small radius. Most often, arc chains are special chains with hinges that allow for freer movement of the chain. In addition, axial displacement control must be provided in the chain so that the ends of the roll do not cling to the walls on the inside of the arc. The easiest way to control axial displacement is to use curved side plates. The second option is to weld a part that provides axial displacement control. In terms of size, the arc chain is usually of the M80 to M160 classes.

Chains of the European series
The arc chain is made with hinges that allow for freer movement of the chain and is equipped with an axial displacement control device.
Characteristics of arc chains:
- Sleeves that are hardened and on the inside.
- On curved side plates, no laborious welding of guide parts is necessary.
- Numerous design and size options.
