Plastic Clamping Blocks

[Ben Martin]

We're running four of the gearboxes and one of the bearing blocks--happy with the results.

I'll echo everyone else's comments about tightening on the gearboxes--we have to make sure everyone has proper training before they attach/detach any bolts from the gearbox due to risk of deforming the plastic.

Running 4 aluminum clamping bearing blocks on the drive train, 1 plastic clamping gearbox as the first stage of the lift.

For the drive train blocks, we had to shave away some powder coat in order to get these on after powder coating. No big deal - they are tight-toleranced for a reason.

There wasn't much finagling to get the plastic clamping gearbox onto the powder-coated rail it lives on. It still slides for tensioning, but takes a lot more force (expected).

Do any teams have experience with these plastic bearing blocks on powder coating?
