Rolling bearing guide ring

A rolling bearing comprising:

• a guide ring having an annular shape with a centered axial opening along a center axis, the guide ring comprising:
• a base portion extending in an axial direction,
• a first side portion extending in a radial direction from a first axial end portion of the base portion, and
• a second side portion extending in a radial direction from a second axial end portion of the base portion,
• wherein the first side portion and the second side portion are integrally formed with the base portion of a one-piece sheet material;
• and
• rolling elements,
• wherein the first side portion is abutting an axial end portion of at least one rolling element of a first row of rolling elements on a first axial side of the guide ring,
• wherein the second side portion is abutting an axial end portion of at least one rolling element of a second row of rolling elements arranged on a second axial side of the guide ring.

A method for manufacturing a guide ring for controlling a position of at least one of rolling elements and a bearing cage in relation to an inner ring of a rolling bearing, the method comprising steps of:

• providing a workpiece of sheet material to be formed into the guide ring,
• forming the workpiece by bending action such that the workpiece is provided with an annular shape having a center axis,
• providing a first side portion by forming the workpiece, and
• providing a second side portion by forming the workpiece,
• wherein a base portion of the workpiece is formed between the first and second side portions, which base portion extends in an axial direction,
• the first side portion extends in a radial direction from a first axial end portion of the base portion, and
• the second side portion extends in a radial direction from a second axial end portion of the base portion.
