PURPOSE:To simplify a ball circulating mechanism and also improve a ball circulating function, by using opposed J-shaped tube members to form ball circulation passages. CONSTITUTION:A pair of opposed J-shaped tube members 3 and 3' are surrounded by a cover 5 to which rubber 4 is bonded, and are fixed to a bearing body 1 by bolts 6. Projecting portions 3A and portions extending therefrom of the tube members 3 and 3' are deeply inserted into a groove 2' of a raceway track base 2 to make scooping operation of balls smooth. |
