Our 'expanding' type pullers are tapped out by a rod inserted from the back of the bearing. Any old metal rod, punch or long bolt can be used, but if you don't have anything suitable handy, we can offer a rejected threaded rod for the purpose.
The rod will be 150-200mm long and 8mm in diameter so can be used with any of our pullers.
Ourtools can be selected either by the bearing size or by the bearing's standard reference code.
Standard references take the form of a three or four digit number, such as 688, or 6902 for example. These codes are often moulded onto the bearing's seal. You might see something like 6902-2RS on the seal. The first digits are the standard reference. The second part (2RS in this case) refers to the seal type and doesn't matter for tool selection.
Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width.
Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
