A method of manufacturing a roller cage for mounting rollers around a circle in a bearing includes a) making a roller cage blank of cylindrical form, b) cutting the cage blank on opposite diagonal sides to form two generally semi-cylindrical halves, c) re-assembling the two semi-cylindrical halves of the cage blank by releasably clamping adjacent cut edges of each semi-cylindrical half together, and d) either before or after the cutting step, forming pockets for mounting a set of rollers in the cage on a circle about the axis of the reassembled cage. The last step d) allows one to provide pockets which mount the rollers in the correct position relative to the axis of the bearing even though the two semi-cylindrical halves when re-assembled no longer form a circle.
A method of manufacturing a roller bearing cage for mounting rollers around a circle in a bearing, said manufacturing method comprising:
The method as claimed in any of the preceding claims in which the cutting step (b) is carried out before the pocket forming step (d).
The method as claimed in any of the preceding claims in which the cutting step (b) is carried out after the pocket forming step (d).
The method as claimed in any of the preceding claims in which step (c) includes releasably connecting adjacent cut edges of each substantially semi-cylindrical half together by means of a clamp.
A roller bearing cage manufactured by the method of any of the preceding claims.
A roller bearing cage for mounting rollers around a circle in a bearing, said roller bearing cage comprising:
