1" Garage Door Torsion Tube Shaft – Hollow Steel Counterbalance Shaft

This 1" tube shaft is designed for compatible garage door torsion spring and counterbalance systems.

The hollow steel shaft runs through the torsion spring assembly and provides the mounting surface for compatible cable drums, bearings, spring cones, shaft collars, and related counterbalance hardware.

Tube shafts are commonly used on residential and light commercial sectional garage doors where a standard 1" torsion shaft configuration is required.

Tube Shaft vs. Solid Shaft

A tube shaft is hollow and is commonly used on standard residential and lighter commercial torsion systems.

A solid shaft may be required for heavier commercial doors, keyed sprocket applications, high-load systems, or configurations where the operator or door hardware specifically requires a solid keyed shaft.

Do not substitute a tube shaft for a solid keyed shaft application without confirming the complete door-system requirements.

Compatibility

Before ordering, verify:

• Required shaft diameter

• Required shaft length

• Existing shaft type

• Cable drum bore

• Bearing bore

• Spring cone compatibility

• Door weight

• Lift configuration

• Operator or hoist requirements

This product is designed for components requiring a 1" tube shaft.

Important Installation Note

The torsion shaft is part of the garage door counterbalance system and may be under significant spring tension.

Torsion spring and shaft installation should be performed by a trained garage door technician. Properly secure the door and fully release spring tension using approved procedures before removing or servicing the shaft.
