SKU CH-PFBB-3FX0Y

Carbon steel torsion springs maintain tension on GT2 timing belts up to 6 mm wide, supplied in a pack of 30 pieces

  • Fits GT2 belts up to 6mm wide for secure tensioning
  • Carbon steel construction delivers strong elasticity and fatigue resistance
  • Compact 12 x 12 x 8 mm size installs in tight printer frames
  • Spring inner diameter 3 mm and outer diameter 5.2 mm match standard GT2 profiles
  • Pack of 30 springs provides enough spares for multiple printer builds

30 GT2 Timing Belt Tensioner Springs

This pack contains 30 carbon steel torsion springs designed for 3D printer timing belt systems. Each spring measures 12 x 12 x 8 mm with a 5.2 mm outer diameter and 3 mm inner diameter. The wire diameter is 1 mm. They fit belt widths up to 6 mm.

Suitable for builders maintaining multiple printers

These springs suit users who need a ready supply of replacement tensioners for GT2 belt systems. The carbon steel construction provides elasticity and fatigue resistance for regular motion cycles. Buyers who need tensioners for wider belts or different belt profiles should look elsewhere.

Handles standard GT2 belt tensioning

The 30 piece quantity provides enough spares for several printers or extended maintenance intervals. Springs install directly into existing tensioner mounts sized for the 5.2 mm outer diameter. They run out when belt widths exceed 6 mm or when mount dimensions differ from the 12 mm housing.

Questions about this item

What belt width must my 3D printer already use for these springs to fit?

The springs fit GT2 timing belts with a width of 6 mm or less.

Will the 5.2 mm outer diameter and 3 mm inner diameter work with the GT2 idler bearings I already have?

The spring inner diameter of 3 mm slides onto standard GT2 idler bearings, while the 5.2 mm outer diameter clears most bearing housings.

How can I confirm the 30 springs are tensioning the belt correctly after installation?

The belt should run taut without slack, the springs should compress evenly to about 8 mm height, and the printer should move smoothly without skipped steps.
