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.

⚠️ 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.
