Altitude Bearings
"Thank you for those amazing altitude bearings! They are perfect." - B. Gentile 8/20/18

Big Bearings Upgrade
Move up from 5" to 12" bearings.
In addition to below: Now also available for inside bearings on 10" SkyWatcher collapsible! Just specify in your order.

Upgrade your
5"-5.5" factory installed bearings with this "drop in" replacement 12" bearing. You'll have smoother motion, finer control, greatly improved balance without springs or counterweights, and no lateral slippage. Bearing mounts on exisiting the altitude bearing and ride outside your mount's side-walls on a support bracket with teflon pads. Once installed, remove the factory bearing pads so the Big Bearing rides freely. We can even do this for mounts with interior bearings - ask us. Requires a drill and Phillips screwdriver. Available finished ready to install or as a kit, rough sanded. All come with telon, FRP bearing strips and screws..
