Description |
|
|
Pulley Type |
GT2.5 Timing Pulley (Synchronous
Wheel) |
|
Tooth Profile |
Rounded tooth profile (specific to
GT2.5, less anti-backlash than GT2) |
|
Tooth Pitch |
2.5mm (the distance between the
centers of two adjacent teeth) |
|
Number of Teeth |
20 Teeth |
|
Belt Width Compatibility |
Designed for 6mm wide timing belts |
|
Bore Diameter |
5mm (inner diameter, for mounting
on a 5mm shaft, e.g., NEMA 17 stepper motor) |
|
Outer Diameter (OD) |
Approximately 16mm (can vary
slightly by manufacturer) |
|
Material |
High-Quality Aluminum Alloy
(common) |
|
Flanges |
Dual flanges (to prevent belt from
slipping off) |
|
Shaft Fixing |
Typically uses 2 x M3 or M4 grub
(set) screws (often included) |
|
Precision |
Designed for reasonably accurate
power transmission and linear motion |
|
Backlash |
While GT2.5 has a rounded tooth
profile, it generally has slightly more backlash compared to the newer GT2
profile, which is optimized for minimal backlash in linear motion. |
|
Applications |
Older 3D printers, CNC machines,
robotics, and other automation projects where precise, non-slipping motion
transfer is required. Note: For new designs, GT2 (2mm pitch) is generally
preferred for better precision and backlash characteristics. |
|
Durability |
Durable and practical due to
aluminum construction. |
|
Color |
Silver (common for aluminum
pulleys) |
|
Weight |
Very lightweight, typically a few
grams. |
