GT2 2mm pitch closed-loop neoprene timing belts for FTC mechanisms. A lighter, more efficient alternative to chain — when installed correctly, timing belts require no tensioning.
Available in 5mm and 10mm widths. Choose by tooth count; pitch length (mm) = teeth × 2.
GT2 belts are not interchangeable with HTD 5mm belts. For HTD 5mm pitch, see HTD Timing Belts.
