Abstract
A rolling-element bearing cage or rolling-element bearing cage segment is formed from aluminum alloy AA6082 and/or AA7020 and may have a tensile strength of at least 350 MPa and/or a yield strength of at least 310 MPa and/or a hardness of at least 100 HBW. Also a method of forming a rolling-element bearing cage or rolling-element bearing cage segment from aluminum alloy AA6082 and/or AA 7020.
Claims16
A rolling-element bearing cage comprising aluminum alloy AA7020 and aluminum alloy AA6082.
A rolling-element bearing cage or a rolling-element bearing cage segment comprising a first side ring or a first side ring segment formed from aluminum alloy AA6082 and/or aluminum alloy 7020;
- and a second side ring or a second side ring segment formed from aluminum alloy AA6082 and/or aluminum alloy 7020;
- and at least one bridge formed from aluminum alloy AA6082 and/or aluminum alloy 7020, the at least one bridge connecting the first side ring to the second side ring or connecting the first side ring segment to the second side ring segment.
A method comprising:
- providing a body of aluminum alloy AA6082 and/or aluminum alloy AA7020;
- and
- forming the body into a rolling-element bearing cage comprising a first side ring, a second side ring and a plurality of bridges connecting the first side ring to the second side ring or forming the body into a rolling-element bearing cage segment comprising a first side ring segment, a second side ring segment and at least one bridge connecting the first side ring segment to the second side ring segment.
