20Teeth Perlin Pulley GT2 without teeth 3mm Bore for Belt 6mm Idler Wheel
The 20 Teeth GT2 Smooth Idler Pulley with 3mm Bore is a precision-engineered idler wheel designed to guide and tension 6mm GT2 timing belts in motion control systems. Featuring a smooth, toothless surface and a 20-tooth equivalent diameter, it minimizes belt wear while ensuring quiet, low-friction operation. The 3mm inner bore allows easy installation on shafts, bolts, or mounting screws commonly used in 3D printers, CNC machines, and automation equipment. Manufactured from durable aluminum alloy or metal, this passive idler pulley maintains proper belt alignment and tension, making it an essential component for reliable linear motion performance.
بكرة التوجيه GT2 الملساء المكافئة لـ 20 سنًا بفتحة داخلية 3 مم هي عجلة توجيه دقيقة مصممة لدعم وشد أحزمة التوقيت GT2 بعرض 6 مم في أنظمة الحركة الخطية. تتميز بسطح أملس خالٍ من الأسنان، مما يقلل من تآكل الحزام ويوفر تشغيلًا هادئًا باحتكاك منخفض. تسمح الفتحة الداخلية بقطر 3 مم بتركيبها بسهولة على الأعمدة أو البراغي المستخدمة في الطابعات ثلاثية الأبعاد وآلات CNC ومعدات الأتمتة. تُصنع من الألمنيوم أو السبائك المعدنية المتينة، وتساعد على الحفاظ على محاذاة الحزام وشده بشكل صحيح لضمان أداء موثوق ودقيق.
The 20 Teeth GT2 Smooth Idler Pulley is a passive belt-guiding component designed for use with 6mm wide GT2 timing belts in precision motion systems. Unlike standard drive pulleys, this idler features a smooth, toothless surface that supports the belt without engaging its teeth directly.
Its outer diameter corresponds to a 20-tooth GT2 pulley size, ensuring consistent belt routing and maintaining proper tension throughout the motion system. The smooth design minimizes friction, reduces operating noise, and helps extend belt life by preventing excessive tooth wear.
With a 3mm bore diameter, the pulley can be mounted easily on M3 bolts, shafts, or custom tensioning mechanisms. Constructed from durable aluminum alloy or metal, it offers excellent wear resistance and reliable performance in continuous-use applications.
This idler pulley is commonly used in 3D printers, CNC machines, laser engravers, robotics projects, and other linear motion systems, where precise belt alignment and smooth operation are essential.
