"Thank you for those amazing altitude bearings! They are perfect." - B. Gentile 8/20/18
Small Bearings Transformed to 12 Inch.


Swap small factory bearings for 12 inch Big Bearings drop-in replacements for smoother motion, finer control, greatly improved balance without springs or counterweights with no lateral slippage. New bearings ride on a support bracket with teflon pads. Once installed, remove the factory installed bearing pads so the Big Bearing rides freely. Just send us a photo of your existing bearings, we will design specific to your telescope.

Requires a drill and Phillips screwdriver. Available finished ready to install or as a kit, rough sanded. All come with telon, bearing laminate strips and screws.

Small Bearings Fitted To Your Tube.

Inside braces are custom cut to your tube's exact diameter, attaching with a 3/8" bolt through a center hole in the bearing clamping braces in place. Equatorially mounted Newtonians or SCTs can use existing rings to put your telescope on a Dobsonian mount. Avaiable with or without an outside 1/8" thick by 3/16" tall lip (as shown), and with or without supports (supports include teflon pads). Kits arrive rough sanded and assembled. Finished arrive ready to use.
