| Product Description | The diameter of these shafts is slightly smaller than listed, so precision ball bearings (ABEC -3 and above) slide on without any tools. This saves you from having to use a bearing heater or mechanical press, which can cause damage. These rotary shafts are also known as drive shafts because they’re frequently used with a motor to drive power transmission applications. All are turned, ground, and polished to tight diameter and straightness tolerances. This allows them to evenly distribute loads, reduce vibration, and improve accuracy and stability. They’re stainless steel, so they resist corrosion. All have chamfered edges to remove sharp corners, reducing damage to bearings, housings, and other components during installation. |
