Radial Roller Bearing Family (60XX, 24 Sizes)

Various sizes of full complement print-in-place roller bearings in standard 60XX ball bearing packages.

The bearing names reflect their ball bearing equivalent package dimensions, making it easy to use these as drop-in replacements where only radial load capacity is required. These are roller bearings — not ball bearings — and are designed to handle light radial loads only. Ball bearings are notoriously difficult to print successfully, making roller bearings a practical and more reliable alternative for FDM printing. The trade-off is that roller bearings cannot carry axial (thrust) or moment loads, so these are best suited for applications where only radial support is needed.

For bearings which can handle radial, axial, and moment loads use these Cross Roller Bearings. They require minor assembly (snaps together, no glue), but they are all around perform better and are more similar to ball bearings. 

⚠️ Please note: These are plastic bearings. They will not match the smoothness, quietness, or longevity of precision metallic bearings. Applying a grease (such as silicone grease) to the rollers is strongly recommended to reduce noise and wear.

Features:

• Print-in-place — no assembly required
• Inseparable construction
• No supports or rafts needed
• Approx. radial play: 0.7mm (0.03in)

Available sizes:

* Inner diameter (ID) is increased by .13mm (.005") and outer diameter is decreased by .25mm (.010") from nominal to reduce interference. Calibrate your X and Y steps if fits are too tight.
