Title:
BALL BEARING FOR LINEARLY MOVING PARTS
Document Type and Number:
WIPO Patent Application WO/1986/002417
Kind Code:
A1
Abstract:
A ball 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 ball bearing, a ball-circulating passage is formed by fitting in a laminated state in a leg portion (3a) of a bearing body (3), in which load ball grooves (3b, 3b') are provided, an intermediate member (2) having upper and lower J-shaped grooves (2a), which are opposed to upper and lower members (1, 1') provided with opposed J-shaped grooves (1a), and upper and lower grooves (2a') connecting the ends of the upper and lower J-shaped grooves (2a), to thereby facilitate the manufacturing of the bearing and reduce the number of parts thereof.
