Specialty Roller Chains
                    
                    Hollow Pin Chain
This chain has hollow pins and the through hole of each pin can be  used to accommodate various rods and attachments. Hollow Pin chain is available  in steel, nickel plated & stainless steel chain.

Sidebow Chain 
 
The increased internal clearances within this chain allow it to  side flex making it ideal for curved conveyors. Sidebow chain uses standard  roller links and special pin links and runs on standard AS sprockets.

Agriculture Chain
A light steel roller chain with the same gearing dimensions as the  equivalent malleable or pintle chains offering a smoother operation. 
CA550 A  heavy duty steel roller chain with greater wear resistance and higher tensile  strength than equivalent pressed steel, malleable or pintle chains

Leaf Chain 
Leaf chain consists solely of pins and link plates assembled  together. Hence it has improved tensile strength compared with roller chain and  better suited for suspension and tension. D.I.D. leaf chains are in accordance  with ANSI standard and are available in two alternatives of AL type and BL  type.
AL Used primarily for light duty and slow speed applications, where little importance is attached to wear resistance. 
BL Used for repetitive high impact loading applications, where more importance is attached to wear resistance.
