  • Keeps belts taut with ten carbon-steel springs

  • Compact 12 mm body suits tight printer frames
  • 1 mm wire gives strong, fatigue-resistant tension
  • Silver finish resists corrosion in continuous use

GT2 Belt Tensioner Springs 10-Pack

This pack supplies ten carbon-steel torsion springs built for GT2 timing-belt systems on 3D printers. They suit hobbyists and small-shop operators who need reliable belt tension without machining custom parts. The springs arrive new and ready to install on compatible printers.

Capacity and Headroom

Each spring fits belts up to 6 mm wide and measures 12 mm long, 12 mm wide and 8 mm high with a 5.2 mm outer diameter, 3 mm inner diameter and 1 mm wire. The carbon-steel construction gives strong elasticity and fatigue resistance for continuous motion cycles. Ten pieces provide spares for multi-axis machines or future maintenance.

Spring Inner Diameter 3 mm

The 3 mm inner diameter is the critical dimension that determines whether the spring slides onto your tensioner shaft or idler pin. Verify this measurement against your printer's hardware before ordering; no other specification in the pack compensates for a mismatch.

Questions about this item

Will the 10 carbon-steel springs work with the GT2 belts already on my 3D printer?

Each spring fits belt widths up to 6 mm, matching standard GT2 timing-belt systems used on many printers.

How can I confirm the springs are seated correctly after installation?

The belt should run taut with no visible slack, and the spring coils should compress evenly without binding during axis movement.

Does the pack include any mounting hardware or just the 10 springs?

Only the 10 silver-coloured carbon-steel tensioner springs are supplied; brackets, screws or belts must be sourced separately.
