Work / Who Are We?
"Thank you for those
amazing altitude bearings! They are perfect." - B. Gentile 8/20/18
up from 5" to 12" bearings.
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,
