Here’s a Challenge: European conveyor chains manufactured in our dedicated plant in the industrialised east coast of China supplying a global market.
Choose Challenge conveyor chains for quality, strength and durability. We select only the best materials with accurately controlled heat treatment and use brand new CNC machines with automatic bar feeding. The result: high precision, long-lasting conveyor chains.
ISO 9001:2000 certified, Challenge employs a highly qualified team of engineers to deliver our vision for consistently high quality at competitive prices.
As specialists in the production of spin-riveted chains, we use high-grade case-hardened alloy steel pins produced on state-of-the-art European machines, giving you the best rivet on any standard chain.
Challenge not only produces the complete standard range in accordance with all DIN and ISO specifications but also offers a limitless range of special chains.
Link plates cropped from high carbon cold drawn steel
To avoid internal stresses associated with guillotined steel, Challenge produces all plates from high tolerance, on size, cold drawn steel bars resulting in a plate better able to withstand fatigue and shock loads.
Bushes with location shoulders and interference fit
For precise assembly; control of inner width and prevention of bush rotation.Bush shoulder length extended to form clearance between inner and outer plates and provide uniform lubrication; increased strength and life. This reduces the possibility of chain seizure.
Case Hardened Alloy steel bushes precision machined from seamless tube
Ensuring minimum distortion and superior concentricity.
Optional Stainless Steel or Nitride treated liner bushes
Hardened Rollers with grinding
Grinding the outer diameter gives excellent wear resistance and good load carrying qualities plus reduced wear on sprockets and a better visual result.
Pins with location shoulders and interference fit
Precise positioning of outer plates adds to strength whilst ensuring accuracy of attachment positioning.
Alloy Steel Seamless Tube used for all Hollow Pins
For wear and shock resistance. Spin Riveted (not coned) for stronger rivet and reduced pin-end stress.
Spin Riveted Induction Hardened Pins in Alloy Steel
For optimum life and the strongest rivet in any standard chain.
Holes precision punched on dedicated progression tooling
Guarantees consistently high tolerance pitch control and strong, fatigue resistant chain.
Attachment and options
CNC welded and integral attachments, special bushes, bearings, Zinc and Nickel plated parts, molykoted pins, bushes and rollers. Plastic rollers, flanged rollers, hardened plates, stainless parts, liner bushes etc. All specials produced to the highest quality with a fast turnaround.
Shot Peened to produce a strong surface and reduce fatigue
Challenge has invested heavily in CNC controlled machinery for optimum batch component conformity. Attachment plates jig assembled maintains position and squareness.
