The cage is in two parts d1, d2 secured together by rivets e and having opposed semi-circular recesses for the balls c. The washers f, which are preferably of brass, are secured to the cage by the rivets e or by brazing or spot welding. The cage may have a fine running clearance with the inner race only as shown, or with the outer race only, or may have more than a fine running clearance with both races. According to the Provisional Specification, when the invention is applied to pressed cages the rivets have spacing sleeves.</p> |
