A roller bearing with pin mounted rollers is provided. The roller bearing comprises: an inner race 11 and an outer race 10; a set of pin mounted rollers 14 rotationally engaging both the inner and outer races 11, 10; and a spacer means 36, 40 to engage each pair of adjacent rollers 14 in the set and adapted to maintain the axes of the pair of adjacent rollers at a predetermined distance apart so that their cylindrical surfaces are maintained at a predetermined distance apart. The spacer means comprises two sets of links 36, 40, a link from the two sets forming a pair of links, one end of the links of the pair engaging with opposite axial ends of a pin 26 mounting a first of the respective pair of adjacent rollers 14 and the links of the pair also engaging with the opposite axial ends of a pin 26 mounting the second of the respective pair of adjacent rollers 14. The roller bearing further comprises anti-rotation means 41, 42, 46 between each pin 26 and at least one of the four links with which it engages to prevent the pins from rotating with the rollers.
