A linear slide bearing for use in, for example, machining center has an integral main body with a channel-like cross-section constituted by left and right skirt portions and a central cavity formed between the skirt portions, the main body having a pair of race receiving grooves formed in the opposing surfaces of the skirt portions confronting the central cavity and non-loaded ball grooves disposed near both ends of respective race-receiving grooves and communicating with the race-receiving grooves. The linear slide bearing further has a pair of bearing races constituted by arcuate members having a semi-circular cross-section, each of said bearing races being provided in its inner surface with a pair of loaded ball grooves.
