Hello group,

Does anyone have an alternate source to Dewalt/Delta Service.net for
bearings for this model drill press? ...
Also, any input regarding how difficult it is to replace them would

be
appreciated as well.



Ball bearings are sold by standard size defined by OD, ID, and race

width.

As well, there are OEM bearings that are not standard and additional
features/styles/etc., including shield, material(s), tolerances, etc.,
etc.


There are but it is extremely unlikely that a non standard bearing would be
used in common drill press.

All sizes are metric.


Except for those that aren't...


Agreed. To split hairs though, the inch is defined as a fraction of the
meter. This being the case, one could say that inches are a metric unit.

You should be able to get bearings from any baering supply house.


Again, assuming they aren't an OEM-"oddball". Likely they are a
standard, but not guaranteed. Going to a bearing supply is the right
choice, though.

$22 may be a little high, but probably not by much.


Not sure of the particular press by the model number so don't know how
large/heavy they are--probably correct the cost differential very
likely won't be huge.

You need a bearing puller pull the old bearings and an arbor press if
you expect to install new bearings without brinelling them.


Will need puller or press to remove them undoubtedly. Depending on
design and tolerances, quite probably would be able to reinstall them
carefully w/ just a block and some care.

Many bearing supply/distribtors have machine shops associated and will
do so if don't want to or don't have the handy neighbor/buddy whose
services are securable w/ the correct beverage...
