- Local availability and branch pickup from Samrand, Pretoria CBD or Cape Town to avoid long import lead times.
- Comprehensive ranges across HTD, GT2 and trapezoidal belts plus matched pulleys and tensioners for reliable motion transfer.
- Support for students and labs with education-friendly packs and clear compatibility guidance for common platforms like 3D printers and CNC routers.
Quick specification callouts
When you order timing belts pulleys online, key specs to confirm are belt profile (HTD/GT2/T), pitch (mm), belt width, pulley tooth count and bore/shaft size. Communica stocks a wide range-check the full collections to compare options.
| Profile | Common pitch | Typical use |
|---|---|---|
| GT2 | 2.0 mm | 3D printers, light motion systems |
| HTD | 3.0 mm, 5.0 mm | Higher torque drives, conveyors |
| Trapezoidal | Varies | Legacy machinery, general power transmission |

Sizing and compatibility essentials
Use these quick checks before you order timing belts pulleys online: confirm the belt pitch and width match the pulley, check the pulley bore or choose one with a removable bushing, and verify centre distance tolerance for tensioning. If you are retrofitting a 3D printer or robot, compare tooth count to keep the same gear ratio and steps-per-mm.
Need an example? If your printer currently uses a GT2 16-tooth pulley with a 2 mm pitch and you change to a 20-tooth pulley, step resolution changes proportionally - plan motor microstepping accordingly.

Selection criteria, calculations and accessory bundles
Choosing the right timing belt and pulley is simpler with a short checklist: belt profile (match to pulley), tensile strength for your torque, width for load capacity, and correct pulley bore or hub option. For most hobby to light industrial projects, GT2 (2 mm pitch) and HTD (3/5 mm) cover the majority of use cases.
Simple drive calculations
Use this pulley ratio formula to estimate output speed or torque changes:
Ratio = Driven pulley teeth / Driver pulley teeth
Example: Driver 16T, Driven 48T => Ratio = 48/16 = 3 (output speed 1/3, torque x3).
ASCII wiring/arrangement for a typical two-pulley belt run:
Motor Pulley (driver) =========== Belt =========== Driven Pulley (idler)
Accessory bundles & compatibility guidance
We bundle belts with matched pulleys, tensioners and mounting hardware so you get a tested combination - ideal for classroom kits or prototype runs. When you order timing belts pulleys online, consider adding idler pulleys and adjustable tensioners to simplify installation and extend belt life.
| Bundle | Includes | Good for |
|---|---|---|
| Printer GT2 kit | GT2 belt, 16T pulley, tensioner | Repairs & upgrades |
| HTD power kit | HTD belt (3 mm), pulleys, busing | Higher torque applications |
