A roller bearing sub-assembly can include a first mounting portion, a second mounting portion spaced apart from the first mounting portion, a first roller disposed between the first and second mounting portions and straps wrapped partially around different portions of the first roller. The first mounting portion, second mounting portion, first roller and straps are configured such that the first and second mounting portions are moveable relative to each other along a selected direction for a distance that is approximately equal to a circumference of the first roller in opposite directions from a mid-stroke position. Linear roller bearing assemblies and methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.
