Locking Capture and Incised Channel |
The Tightrope Walker:
"Balance
is everything" - if your bearings are undersized, you will have
balance problems. The width of an altitude bearing emulates a balance
pole used by tightrope walkers. The pole spreads balance out over
a large base. Too short, the tightrope walker can't balance. Think of
your own balance, you're easier to tip with your feet close together.
Altitude bearings function the same. Don't shortchange yourself, widen
your telescope's balance. And a bonus: larger bearings provide finer
incremental movement control.

Small factory under-balanced bearings with
Big Bearings 12" upgrade.
Small
factory bearings standard on mass produced Dobsonian telescopes are an
inherent design flaw causing balance problems. 12" Big Bearings solve
this issue, improving balance, motion, giving finer control, adding a
lock mechanism for eyepiece change.
All parts included: bearings, supports, support screws, teflon, bearings
laminate, fine tuning assembly. Requires glue for laminate (contact cement),
Philips screwdriver and 3/4" longer bearings bolts.
Standard 12"
and 18" Bearings.
Standard
12" and standard 18" altitude bearings with incised channels
for fine tuning guides and sideboard supports. Both 12" and 18"
designs incorporate cutouts to allow easy lifting and carrying of your
telescope. Inside braces (shown on left bearing) are individually cut
to precisely match your telescope tube outside diameter. Choose among
these options:
