What is a 3 jaw puller used for?
3-Jaw Puller You can use them to remove gears, pulleys, wheel hubs, all kinds of hard to remove parts. They come in several sizes and are inexpensive. Every garage should have three sizes of 3-jaw pullers in the drawer.
What does a 2-Jaw puller do?
2-jaw pullers are popular for jobs that require removal of gears from very tight spaces. 3-jaw pullers are commonly used for a more even pull if space permits. The 2- jaw puller is noted for effectively handling small gears that require immense force to remove.
How do I choose a bearing puller?
The decision of which puller to use is dependent on many factors. You’ll first need to establish whether you need an external or an internal bearing puller. If the component that you’re removing is seated on a shaft and is freely accessibly from the outer diameter, you’ll need an external bearing puller.
How do you heat a bearing for removal?
Removing bearings with induction heaters You can wrap the coils of the induction heater around the bearing. This allows you to heat the bearing very quickly and with great precision, without heating the shaft. This allows you to lift the shrink connection quickly and easily.
Will heating a bearing ruin it?
A good general rule of thumb is to heat bearings to a temperature 150 F greater than shaft temperature. This is sufficiently warm to allow the bearing to slide over the shaft while not hot enough to damage any components. In any case, do not heat open bearings above 250 F.
What temperature do you heat a bearing?
Hot mounting Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 °C (257 °F), because the material may change metallurgically and produce alterations in diameter or hardness.
What temperature is too hot for a bearing?
Bearing Temperature Conditions Most precision installed and lubricated equipment will operate at less than 180 degrees F. A bearing temperature that is less than 180 degrees F is typically considered acceptable (see the chart below).
