Gates 188-2GT-6 RF Closed Loop Belt

Genuine Gates 188-2GT-6 RF closed-loop timing belt for compact 2GT/GT2 motion assemblies: 188 mm loop length, 6 mm width, 2 mm pitch, round-tooth profile, black neoprene rubber construction with fiberglass tensile reinforcement.

Why use this belt

• Closed loop: molded endless belt for fixed-center short runs where you are not cutting belt to length.
• Gates PowerGrip GT2 family: low-stretch fiberglass cord and rubber body for repeatable positioning in small motion systems.
• Voron BOM-spec size: the 188 mm × 6 mm Gates GT2 loop is a common Voron motion belt size, also sold by Voron-focused suppliers as 188-2GT-6RF.
