How to optimise round rail performance and cost with informed linear bearing selection

Square rail, which is typically the more expensive option, has a higher load capacity and tighter accuracy. Round rail
offers distinct cost and reliability advantages for certain applications, but maximising those advantages depends on specifying the right bearing to
minimise friction in each application.

Designers must often choose between plain bearings, often called bushings, and ball bearings. Within
each type, they will have more options that impact price, performance, maintainability, and durability.

Understanding these options early in the
design cycle will optimise the performance and cost of the linear motion application.
