The Fix For Small Bearings.


Big Bearings provide smoother motion and finer incremental control than small factory bearings, while giving you secure balance without gimmicky springs or clamps. These drop-in replacements are a simple solution, in many cases just screw in the new Big Bearings and bearing supports.

E-mail us a photo of your existing bearings, we'll ask a few dimensions. Its that easy.

Big Bearings options.



Small Fitted Bearings For Tubes or Mirror Boxes.
Small bearings are up to 12" diameter. We cut the inside facing braces custom to fit your tube's outside diameter. Bearings attach using a 3/8" bolt through the center hole, clamping the curved braces to the tube.

Equatorially mounted Newtonians or SCTs can use their existing rings attach bearings for Dobsonian mounting. Available with or without supports (see supports below). Kits arrive rough sanded and assembled. Finished arrive ready to use.

Bearing options:
Bearing surface diameter?
Tube diameter, or mirror box mount?
Large Bearings For Mirror Boxes Or Big Tubes.
Bearings from 12" to 23" for mounting on flat sided mirror boxes or precisely fitting telescope tubes using inside braces shown on right (clamped to tube with 3/8" center bolt). Kits are rough sanded and assembled but not spray finished.

Bearing options:
