What is the GreyT Turret (11” ID)?
The GreyT Turret (11” ID) is the second iteration of the GreyT Turret. With this new
design, there are fewer parts making the system much less complex and more robust
overall. Just like the original, the new GreyT Turret (11” ID) is one of the simplest and
most accessible turreting systems on the market. It can be used to aim a shooter or
other mechanism in a different direction than your robot is facing. Combine with vision
to get automated targeting, or control manually to point a mechanism wherever you’d
like!
Notable Improvements and features:
• Smooth Rotation
• Compatible with VersaPlanetary
• Compatible with GreyT Shooter (9.5”)
• Easier to assemble and maintain
• Fewer parts on the bearing stack-up
• Compatible with thin section bearings
• No longer have to tension any chain

Step 1
Bolt the GreyT Turret Ring and the GreyT Base plates together. The plates can be bolted
to whatever tubes the turret is mounted to, if desired.
Note: The Turret Ring plate has a smaller turret hole then the Turret Base� Make sure
that the turret is assembled with the plates oriented correctly�

Step 2
Press the 1/2” ThunderHex ID x 1-1/8” OD Flanged Bearing in to the assembly from Step
1. For this turret, the bearing must be pressed in from the bottom of the assembly.
Note: If you plan on using the turret with a compatible thin section 12�5” OD bearing
(SA120XPO), the Turret Base and Ring plates will have to be tapped together� This will
allow you to use #10-32 x 3/8”L Bolts (WCP-0252) to constrain the thin section bearing�

Step 3
Slide the 1/4”-20 x 1-1/4”L Bolts through the holes marked in green below. Slide all
components on to the bolt as shown in the image below. Make sure there is one 0.03”
thick Steel Washer between the plate and each 1/4” ID x 3/4” OD Radial Bearing.
Repeat this step for the remaining seven bearing bolt holes.
While assembling the parts in this step, use a piece of tape to hold the head of the bolt in
place so that the bolt does not fall out. This will also help in future steps.
Warning: Failure to install the washers will greatly increase the friction in the system
and may result in the turret not being able to rotate.

Step 4
Rest the assembly from Step 2 on top of the 1/4” ID x 3/4” OD Radial Bearings installed
in Step 3. This step is assembled upside down, meaning that the Turret Ring plate will be
the plate that rests on the 1/4” ID x 3/4” OD Radial Bearings.

Step 6
Install the Turret Gear (140T) sections as shown in the image below. The c-bores on the
gearsectionsshouldslottogethermakingthegearasingle,at1/8”thickplatewhen
bolted down.
Once the gear sections are fully seated, tighten the nuts until there is no wiggle in the
bolts.
Note: Make sure not to overtighten the 1/4”-20 Nuts as this may cause the bearings to
clamp the Turret Ring plate, creating unnecessary friction in the assembly�

Step 7
Slide the 10T Steel Spur Gear and Clamping Shaft Collar onto the VersaPlanetary with
Falcon 500. Then bolt the VersaPlanetary to the assembly from Step 6 using the 3/8” OD
x 1-1/4”L Spacers and #10-32 x 1-3/4”L Bolts.
Slide the Clamping Shaft collar and 10T Steel Spur Gear up until the spur gear is resting
against the ThunderHex bearing installed in Step 2. Tighten the Clamping Shaft Collar to
keep the gear in place.
Note: The 10T Steel Spur Gear must mesh with the gear sections installed in Step 6�

FAQ
Q: Are the 3D printed washers between the bearings needed?
A: Yes, these washers are required. They prevent the bearings from rubbing against each
other. This may cause the turret to not rotate or be hard to rotate, even by hand.
