SHELL-SHAPED FULL TYPE ROLLER BEARING AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To easily install a needle-like roller in an outer ring, by easily inserting the needle-like roller into a holding space from a roller insertion groove. SOLUTION: This shell-shaped full type roller bearing 1 has the annular outer ring 2 and a plurality of needle-like rollers 3 arranged inside this outer ring 2. The roller insertion groove 4 is formed in one roller holding part 24 in the axial direction of the outer ring 2, and an end part of the needle rollers 3 is inserted into the holding space S via the roller insertion groove 4. The roller insertion groove 4 is formed larger in a width in the peripheral direction than an outer diameter of the end part in the axial direction of the needle rollers 3, and shorter than the length L1 in the axial direction of the needle rollers 3 in a distance L2 up to a groove bottom part 41 from an inside surface of the other collar part 22 in the axial direction. A slit 42 extending outward in the axial direction is formed on both sides in the peripheral direction of the groove bottom part 41 of the roller insertion groove 4. COPYRIGHT: (C)2010,JPO&INPIT
