Comparison of Chains, Belts and Belts WITH ERO Joint® connections
Which is the best choice for transmitting power? :
- A chain,
- A Timing belt,
- An ERO Joint® mechanically assembled Timing belt
These three solutions are used in industry:
Chain : more flexible (easy to fit, very wide range)
Belt: transmits more power (the belt withstands higher rotation speeds than those accepted by a chain), and is cleaner (no need to lubricate).
ERO Joint® Timing belt: advantages of belts and flexibility of chain assembly (ERO Joint® belts are produced open and then closed on the machine like a chain).

Conclusions and results of the Chain - Belt - ERO Joint® Belt match
Ease of assembly - Winner: ERO Joint® chains and belts.
Belts are closed, so it is easier to assemble an open chain and close it in the machine than a closed belt.
ERO Joint® belts are supplied open and closed on the machine. So it's also easier to assemble an ERO Joint® Belt than a chain.
Repairability - Winner : Chain
A chain can be repaired using a replacement link. The Belt must be completely replaced.
Efficiency - Winner: Belt
Belts weigh less than chains. Efficiency is better.
Durability - Winner : Belt
Belts generally last at least twice as long as chains. ERO Joint® belts can last as long as closed belts, depending on conditions of use.
Maintenance - Winner : ERO Joint® Belts.
The Belt requires no lubrication and generally no tension adjustment.
Cost - Winner depends on application.
Weight - Winner: ERO Joint® belts and belting.
Noise - Winner: ERO Joint® belts and belting.
Belts are quieter than chains. ERO Joint® does not generate additional noise on the Belt.
Cleanliness - Winner : ERO Joint® belts.
Belts do not require lubrication. Chain needs lubrication, and dust clumps together generating dirt.
Size available - Winner : ERO Joint® Belt and Chain.
All chain lengths can be made by adding links. ERO Joint® belts can be made in any length or width. Closed Timing belts are only manufactured to a certain standard length.
Temperature resistance - Winner: Chain
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. - Winner : Belt
Belts can be made from a variety of materials (rubber, PU, ....), giving you more options than chains.
