An X-ring chain has the following differences and advantages compared with an O-ring chain:
- The X-ring has 4 contact points in contrast to 2 contact points with the O-ring version
- This means higher flexibility and better running characteristics for the X-ring chain
- The spring effect of the X-ring guarantees consistent and permanent lubrication
- This means a significantly longer service life for the X-ring chain
- The X-ring provides a better seal against penetration by water and dirt
