#013 : Bearing mounting/retaining method - 3
Three bearing retaining components used are marked with (*) below.
Example 1 (See [Fig.1])
| This is an example of rotating shaft retention using a bearing holder set (T-shaped two bearing type, or bottom mount two bearing type) and bearing nuts with anti-loosening set screws. Loosening of the bearing nut is prevented by use of a set screw and a set piece made of copper alloy. The set piece made of soft copper alloy is first inserted in a screw hole, and a set screw is tightened to crush the soft alloy piece on the shaft thread to prevent the bearing nut from loosening. |  |

Example 2 (See [Fig.2])
| This is an example using bearing holding pins. A bearing holding pin holds against the inner ring O.D. from the end side, and a collar from the inside is pressed against the inner ring O.D. of the bearing from the other side to fix the bearing to the shaft. | |
