Pulley T2.5 20 Teeth Hole 5mm: Reliability for synchronised transmissions
T2.5 timing pulleys are an essential component for those who require precise and reliable motion transmission. Thanks to their specific profile, they are designed to ensure optimal engagement with the belt, reducing kickback due to acceleration and changes of direction. With DHM, choose selected components to offer mechanical stability and a long service life in your automation projects.
What is the 20-Tooth T2.5 Pulley?
It is a transmission element made entirely of aluminium, characterised by a pitch of 2.5 mm. This standard is particularly appreciated in the hobby and industrial sectors for its ability to handle synchronised movements effectively. The 20-tooth structure provides an excellent compromise between movement resolution and fluidity, making it compatible with nylon-reinforced neoprene or polyurethane belts with a steel core.
Why choose our T2.5 pulley?
Designed to meet the precision requirements of modern mechanics, this pulley offers several technical advantages:
- Reduced Backlash: The design of the teeth is optimised to minimise positioning uncertainties when reversing motion.
- Lightness and Robustness: The aluminium construction ensures reduced inertia without sacrificing structural strength.
- Belt Protection: Equipped with a double side flange, it ensures that the belt stays perfectly in place even during rapid work cycles.
- Instant installation: Supplied complete with steel fixing screws for a secure hold on the 5 mm motor shaft.
Note on manufacturing tolerances
We work to ensure the highest quality consistency, however, due to possible variations between production batches, actual measurements may differ from those stated on the data sheet by ±2 mm (except for internal bore). If your project requires specific dimensions or precise millimetre tolerances, we recommend that you contact us prior to purchase for direct verification of stock measurements.
When to use the T2.5 20-Tooth Pulley?
The standard 5mm hole makes it ideal for direct mounting on the most common stepper motors (such as NEMA 17), finding application in:
- 3D printers and plotters: For handling motion axes requiring a T2.5 pitch.
- Small CNC systems: Perfect for pantographs and engravers where repeatability of motion is a priority.
- Robotic Prototyping: Used in automation systems requiring constant synchronous transmissions.
Package contains: 1 x Pulley T2.5 H6 hole 5 mm 20 teeth
