<p>A bearing for linearly moving parts, which is used to guide a linearly moving part, such as a table in a machining tool or a positioning table. In this bearing, a circulating passage for balls (8, 28) is formed by jointed tubes (3, 3') each of which consists of two opposed, cross-sectionally J-shaped members, or a combination of a member of a jointed tube (23a) consisting of two opposed, cross-sectionally U-shaped members and having a belt-like connecting portion (23c), and a member of a jointed tube (23b) consisting of two opposed, cross-sectionally J-shaped members, to thereby facilitate the manufacturing and assembling of the bearing and reduce the number of parts thereof.</p> |
