Precision Needle Bearings for Extruder Upgrades

These 3x5x7mm metal needle bearings are designed as direct replacements for worn or damaged sleeves in Btech dual-gear extruders. They restore smooth filament feed and improve dimensional accuracy during printing. Available in packs of 10 or 15 pieces for convenient maintenance.

Ideal for DIY Maintenance and Spare Stock

Suited for hobbyists and makers who service their own direct-drive extruders and want inexpensive spares on hand. Not suitable for printers that use different bearing dimensions or bushing-style extruders without modification. Buyers needing sealed or flanged variants should look elsewhere.

Compact Hardware for Direct-Drive Builds

Each bearing measures 3mm inner diameter, 5mm outer diameter and 7mm length, fitting the standard cavity in compatible dual-gear assemblies. The lightweight metal construction adds minimal mass to the moving carriage. No lubrication or additional hardware is included in the package.

Can I mix these new bearings with the original ones still in my printer?
