FAQ — XRC® Chain Quality and Selection
What should you look for when choosing a quality roller chain?
Roller chain quality depends on dimensional accuracy, component control, lubrication and preparation for operation. XRC® chains by Chiaravalli Group address these factors through batch checks on plates and pins, tight manufacturing tolerances, industrial pre-lubrication with Fuchs® oils and pre-tensioning. Selection must also account for the application’s operating conditions.

What are the key quality features of XRC® chains by Chiaravalli Group?
XRC® chains combine three technical features: automated pre-lubrication with high-performance Fuchs® oils, pre-tensioning to reduce initial bedding-in elongation, and controlled manufacturing tolerances to maintain consistent chain pitch. Together, these features contribute to reliable operation and consistent engagement with sprockets.

Why is pre-lubrication important for XRC® chains?
Pre-lubrication prepares the chain for initial operation. XRC® chains undergo an automated industrial process using high-performance Fuchs® oils, helping to reduce friction and provide initial corrosion protection. Lubrication during service should be determined according to operating conditions and the applicable technical guidance.

What is the purpose of pre-tensioning XRC® chains?
Pre-tensioning XRC® chains reduces the initial elongation caused by components bedding in during the running-in period. This preliminary treatment contributes to initial chain stability. Bedding-in elongation is different from the wear-related elongation that develops during service.

Why is consistent pitch important in a roller chain?
Consistent pitch promotes correct engagement between the chain and sprocket. In XRC® chains, batch checks on plates and pins, together with tight dimensional tolerances, help maintain consistent pitch and regular meshing. This matters in both power transmission and dedicated material handling configurations.

Can XRC® chains also be used for industrial material handling?
The range includes XRC® Attachment Chains for light conveying and product positioning within machinery and industrial systems. Bent attachments, straight attachments and extended pins allow crossbars, flights and dedicated supports to be fitted. Applications include packaging, intralogistics and food industry machinery, with the configuration selected according to operating conditions.

Can XRC® Attachment Chains be customised?
XRC® Attachment Chains offer different combinations of chain size, attachment geometry and attachment spacing. Standard attachment chains can be supplied cut to length; additional sizes and AISI 304 stainless steel or nickel-plated versions are available on request. The Chiaravalli team can help confirm the required configuration.

How do you select the right XRC® chain for a machine?
Selecting an XRC® chain starts with the required function, operating conditions and dimensions specified in the design. For XRC® Attachment Chains, attachment type, spacing and material must also be defined. Chiaravalli’s technical support team helps match application requirements with the available configurations.

Where can you find technical documentation for XRC® chains?
Technical documentation is available on the Chiaravalli website under Download → Catalogues → Chain Technical Appendix. For confirmation of dimensions, configurations and options available on request, contact the Chiaravalli team with details of your application and chain requirements.
