Final answer:
A bearing heater is used to expand the inner ring of the bearings for easier installation onto the screw shaft.
Step-by-step explanation:
When preparing a ball bearing screw for installation, a tool called a bearing heater is used to expand the inner ring of the bearings.
The bearing heater is an electric or induction heating device that applies heat to the bearing to expand it and allow for easier installation onto the screw shaft. This is done to ensure a proper fit and reduce the risk of damage during installation.
By using a bearing heater, the inner ring of the bearing can be quickly heated, causing it to expand and make it easier to slide onto the screw shaft. Once the bearing cools down, it contracts and creates a tight fit, providing smooth operation of the ball bearing screw.
When preparing a ball bearing screw for installation, use a bearing heater to expand the inner ring of the bearings. The process of applying heat allows for thermal expansion, making it easier to install the bearing onto the shaft without causing damage to the bearing or the shaft. A controlled and uniform heating process provided by a bearing heater is essential for an effective installation, as it prevents uneven expansion and potential damage to the bearing's internal structure.
