Needle Bearing 3x5x7 is a compact hardened steel bearing used in compatible 3D printer extruder assemblies, including Voron Stealthburner, Clockwork, BMG-style, Btech-style, and CR10S Pro setups. It is designed for small drive mechanisms where smooth rotation, compact sizing, and proper fitment matter.

This Needle Bearing 3x5x7 is a compact hardened steel bearing used in compatible 3D printer extruder assemblies. It is commonly used in small drive mechanisms where a 3mm inner diameter, 5mm outer diameter, and 7mm length bearing is required.
This bearing is intended for compatible direct-drive and Bowden-style 3D printer extruders, including Voron Stealthburner, Voron Clockwork, BMG-style extruders, Btech-style extruders, and CR10S Pro-style drive assemblies. Always confirm the required bearing size for your exact extruder before ordering.
The Needle Bearing 3x5x7 size makes it useful in compact extruder drive assemblies where space is limited. For accurate fitment, confirm your printed part, shaft, and extruder design call for a 3mm inner diameter, 5mm outer diameter, and 7mm bearing length.
The current product page identifies this part as used on the Voron Stealthburner. Voron’s own StealthBurner documentation also highlights careful bearing handling during assembly, including avoiding damage when pressing bearings onto shafts. You can review the official Voron StealthBurner assembly manual for build-specific guidance.
This bearing is listed as hardened steel, making it suitable for compact drive applications where strength and wear resistance are important. Needle-style bearings are often chosen where a small bearing package is needed for rotating shafts or drive components.
Because many extruder designs use similar-looking but different-sized bearings, do not rely on appearance alone. Measure your existing bearing or check your extruder bill of materials before ordering. If your build requires a different size, browse our bearings and pulleys category for other options.
Each order is handled by dnb3D in Marathon, Ontario, Canada. This small replacement part is a practical item to keep on hand for printer maintenance, extruder rebuilds, and Voron-style toolhead assembly work.
Below are the confirmed and recommended specifications for this Needle Bearing 3x5x7. Please verify the inner and outer diameter values before publishing, as the current live page appears to have the ID and OD reversed in one location.

Before installing this Needle Bearing 3x5x7, confirm that your extruder, toolhead, or printed part is designed for a 3mm ID x 5mm OD x 7mm bearing. Similar-looking bearings can have different dimensions, so measuring the original bearing or checking your extruder bill of materials is recommended.
Install the bearing squarely and avoid forcing it into printed parts, shafts, or housings. If the fit is too tight, inspect the printed part for excess material, elephant foot, shrinkage, or dimensional inaccuracy before applying pressure. Pressing a bearing onto an oversized shaft or into an undersized hole may damage the bearing or the printed component.
For Voron Stealthburner, Clockwork, BMG-style, Btech-style, and CR10S Pro-style assemblies, follow the correct build manual or extruder instructions for your specific setup. Do not assume compatibility based on product appearance alone.
Keep bearings clean and dry before installation. Avoid dropping, crushing, contaminating, or exposing the bearing to dust, moisture, oils, solvents, or abrasive debris. Store unused bearings in a small sealed bag or parts organizer until needed.
If your extruder develops noise, rough movement, inconsistent filament feeding, or visible bearing wear, inspect the bearing and related drive components. Replace worn bearings as needed and check that shafts, gears, printed housings, and tension settings are properly aligned.
