Looking for sealed tapered roller bearings

[Stan the Man]

Hello all,
I am replacing the stock, head stock bearings in a Grizzly G8688 7x12 lathe, I am trying to find sealed tapered roller bearings that will fit. Currently I have unsealed tapered bearings but would prefer to return them and purchase the sealed kind. Can anyone post a link to where I might find them here in the U.S. or provide a Company name and part number so I can look them up. I rather not have to import them from the UK as the shipping is outrageous. Thanks in advance.
Stan.

Contact Timken. They may have what you need.

Honestly never seen or heard of taper roller sealed bearing. Now a sealed roller maybe but you usually have a separate seal. What’s your bearing numbers?

You're looking for a rare bird indeed.

Stan, What method of lubrication is in place now? Al.

Hundreds of people have done the upgrade on the 7 X 12 lathes with "unsealed" tapered bearings. I have not heard of anyone who has experienced bearing failures with them.

Not sure if such a beast exists. I've never seen or heard of one.

Sealed bearing have a much lower rpm limit than open. In a spindle bearing you want tight clearance and the tapered bearing will generally have some load to reduce both radial and axial runout. If a machine is designed for open bearings in a precision application there is no benefit to sealed and potentially additional risk. Can you tell I'm not a fan ? Dave

Never heard of such an animal ---

A taper roller bearing cannot be sealed becuase of the cup and cone design.
