Y/A axis carriages:

• Machined out of 1" thick aluminum for highest ridigity.

• Integrated primary belt drive.

• Integrated secondary constant-pressure rack & pinion drive system.

• Symmetrical motor force engagement design for both directions.

• Z-axis stepper mounting shelf with integrated thrust bearings.

• RM3 12mm main bearings and RM2 3/8" bearings for Z-axis gantry motion.

• Integrated mounts for hall effect home switches and e-chain shelf.

• Fully assembled, ready to be placed on the rails.

• Available in Nema 23 and Nema 34 stepper sizes.

• Polished aluminum faces as shown.

• Belt tensioning tool.

NOTE: Some images are shown with optional brygga electronics set.

Placement of Y/A carriages onto the rails:

Loosen the set screws on both bottom spacers of the large bearings.

Do not loosen the set screw on top bearing!

Using a 3/4" wrench, loosen the bottom main bearing bolts.

Loosen the bolts to slightly tilt them down.

Place the top bearings of the carriage on the rail.

Keeping the bolts tilted, align the bottom bearings with the bottom rail.

Using the set screws, raise bottom bearings up against the rail. Slowly tighten one of the bearing bolts while checking bearing pressure on the rail. Back off if it is too tight, loosen set screw an eigth of a turn and slowly re-tighten bolt again while checking bearing pressure. Repeat until you have a snug but not too-tight setting.

Repeat procedure for the other bearing.

DO NOT lock the bearings on the rails! Damage to bearings or other parts could occur!

You should be barely able to turn the bottom bearings with your figers once everything is tightened down.

Once set, roll the carriages by hand on the rails and check for tight spots. If necessary, re-adjust bearing pressure for those tight spots.
