The hollow pin chain is designed by a hyperbolic arc chain to reduce the friction. It is used in places where the power is relatively large and the running speed is slow. It has obvious advantages over the belt drive, such as pneumatic compressors.
Hollow pin chain for conveying, single pitch, double pitch, long pitch. Attachments or crossbars can be inserted into any chain link without the need to disassemble the chain. The double-pitch chain has large rollers and small rollers; the thickness of the chain plate is regular and thick; the attachment (bending plate) has four forms: single-sided single hole (A1 type), single-sided double hole ( Type A2), double side single hole (K1 type), double side double hole (K2 type).
