Ball bearings

The chain can be designed with ball bearing rollers

In order to reduce the resistance encountered by a chain, when it is transported across its rollers, the chain can be designed with ball-bearing rollers. Depending on the load, one can also opt for barrel or needle bearings. The static load of the ball bearings tends to be lower compared with a traditional roller. In addition, very high temperatures in which the chain has to function can reduce the applicability of the use of ball bearings.
