Small Rollers Scroll Wheels Pulley's WITH BEARINGS FOR 3D PRINTER DELTA (KOSSEL)
The Small Rollers Scroll Wheels Pulley with Bearings is a replacement part for Kossel and other Delta 3D printers. Features an M6 screw diameter and 19mm wheel size with integrated bearings for smooth, friction‑reducing motion along the printer’s aluminum extrusions. Essential for maintaining the precision and stability of Delta kinematics such as Kossel K800. Easy to install and ideal for restoring worn‑out wheels or upgrading a printer’s carriage system.
بكرات صغيرة وبكرات وبولي بعجلات بمحامل هي قطعة غيار لطابعات كوسيل ودلتا ثلاثية الأبعاد. تتميز بقطر لولب M6 وحجم عجلة 19 مم مع محامل مدمجة لتوفير حركة سلسة وخالية من الاحتكاك على طول القضبان الألومنيوم للطابعة. ضرورية للحفاظ على دقة واستقرار أنظمة دلتا الحركية مثل Kossel K800. سهلة التركيب ومثالية لاستبدال العجلات البالية أو ترقية نظام العربة في الطابعة.
The Small Rollers Scroll Wheels Pulley with Bearings is a precision component designed specifically for Delta‑style 3D printers, particularly the Kossel K800 and its variants. These wheels act as the interface between the printer’s moving carriage and its vertical aluminum extrusions (typically 2020 or 2040 profiles). By rolling along the extrusions, they guide the print head with minimal friction and backlash.
Each wheel measures 19mm in diameter and is fitted with a high‑quality bearing to ensure smooth, quiet rotation. The M6 screw (likely the axle or mounting screw) provides secure attachment to the carriage. The wheels are often referred to as “V‑slot wheels” or “pulleys” and are critical for maintaining the precise movement required in Delta kinematics.
Over time, original wheels can wear out, develop flat spots, or accumulate dirt, leading to poor print quality. Replacing them with these bearings‑equipped rollers restores smooth motion, reduces vibration, and extends the life of the printer.
