ProAm SolidTrax Dolly Wheel Assembly 70lbs

The ProAm SolidTrax Dolly Wheel Assembly is a universal track wheel assembly built for camera support systems. It features a robust aluminum bracket with four 53mm polyurethane wheels and eight precision bearings. The unit supports equipment weighing up to 70lbs (31.75kg) and operates on tracks ranging from 3/4" to 1.5". Sold individually, it allows builders to customize dolly length and configuration.

Filmmakers needing smooth track movement

This assembly suits filmmakers and photographers building DIY or professional dolly rigs who need quiet, vibration-free travel across variable track widths. The 70lb capacity handles many cinema cameras and accessory loads. It is not for buyers needing motorised drive systems, integrated braking, or a complete dolly platform with included track sections. Solo operators requiring ultra-compact folding mechanisms should evaluate dedicated portable sliders instead.

Verify track compatibility and mounting pattern

Confirm your existing track tubing or rail system falls within the 3/4" to 1.5" width range for proper wheel engagement. Check that your dolly chassis or mounting plate aligns with the bracket's multiple mounting points for secure attachment. Ensure the combined weight of your camera, lens, and accessories does not exceed the 70lb limit per wheel assembly used in your configuration.

Questions about this item

What mounting hardware do I need to attach the 53 mm polyurethane wheels to my track system?

The aluminium bracket includes multiple mounting points so you can bolt or clamp the assembly directly to your dolly platform or rig.

Will the 53 mm wheels run smoothly on my existing 3/4 inch aluminium track?

Yes, the assembly is designed to traverse track sizes from 3/4 inch up to 1.5 inch without modification.

How can I verify the dolly is gliding correctly after I install the four wheel assemblies?

Push the loaded rig along the track; it should move silently with no vibration and support up to 70 lbs without binding.
