ERO Joint® Chain and Belt Comparison

Courroies à assemblage rapide ERO Joint

Chains vs. Timing belts vs. ERO Joint® Timing belts

Which is the best power transmission system? Chain, timing belt or ERO Joint® mechanically assembled timing belt?

The industry uses all three systems:

  • Chain: more flexible (easier to assemble, available in all lengths)
  • Belt: more transmissible power (withstands higher rotation speeds), cleaner (no lubrication required),
  • ERO Joint® Timing belt: belt advantages and chain assembly flexibility (ERO Joint® belts are produced open and closed on the machine like a chain).

Chain vs. Belt vs. ERO Joint® Belt

Winner Comment
Easy assembly ERO Joint® chains and belts The belts are closed, so it's easier to assemble an open chain and close it in the machine than a closed belt. ERO Joint® belts are delivered open and closed on the machine. It is therefore just as easy to assemble an ERO Joint® belt as a chain.
Repairability Chains A chain can be repaired using a replacement link. The belt must be completely replaced.
Efficiency Belts Belts weigh less than chains. Better efficiency.
Durability Belts Belts generally last at least twice as long as chains. ERO Joint® belts can last as long as closed belts, under certain conditions.
Maintenance ERO Joint® belts and belting systems The belt requires no lubrication and generally no tension adjustment.
Price The winner depends on the application
Weight ERO Joint® belts and belting systems
Noise ERO Joint® belts and belting systems Belts are quieter than chains. ERO Joint® generates no additional noise on the belt.
Cleanliness ERO Joint® belts and belting systems Belts don't need lubrication. The chain needs lubrication, and the dust agglomerates, generating dirt.Les courroies n'ont pas besoin d'être lubrifiées. La chaîne a besoin d'être lubrifiée, et la poussière s’agglomère générant de la saleté.
Available sizes ERO Joint® chains and belts All chain lengths can be made by adding links. ERO Joint® belts can be manufactured in any length and width. Closed timing belts are only manufactured to a certain standard length.
Temperature resistance Chains The general temperature range for belts is -30 to +80°C. The temperature range for chains is wider.
Chemical resistance to water, acid, oil, UV, chlorine, etc... Belts The belt can be made from a variety of materials (rubber, PU, ....), allowing more possibilities than chains.
