Key Features

• High Load Capacity: Rolling elements maintain precise spacing between moving parts, reducing rotary friction while supporting both radial and axial loads — ideal for demanding mechanical applications.
• Durable Carbon Steel Construction: Manufactured from high-grade bearing and carbon steel for exceptional resistance to heavy-load deformation and long-term wear.
• Sealed Double-Shield Design: Pre-lubricated and double-shielded (ZZ) to lock in grease and keep out dust, debris, and contaminants — extending bearing lifespan significantly.
• High Precision Machining: Fine workmanship ensures tight tolerances, quiet operation, and a long service life in both high-speed and low-speed environments.
• Versatile Compatibility: Suitable for 3D printer axes, CNC router pulleys, skateboard wheels, sliding windows and doors, electric motors, fans, and more.
• Great Value Pack: Receive 10 bearings per order — always have spares on hand for maintenance and repairs.

Frequently Asked Questions

Q: What bearing models are included in this 10-pack of flange ball bearings?

A: This listing covers multiple deep groove flanged ball bearing models, including 626ZZ, 625ZZ, 685ZZ, 607ZZ, 623ZZ, 6900ZZ, 688ZZ, and 687ZZ. Please confirm the specific model variant you need before purchasing, as options may vary by selection.

Q: Are these bearings suitable for 3D printer upgrades and repairs?

A: Yes! These precision sealed ball bearings are widely used in 3D printer builds and repairs — particularly for tensioner pulleys, idler wheels, and motion system axes. Their double-shielded ZZ design keeps lubricant in and debris out, making them an excellent choice for FDM and CoreXY printers.

Q: What is the bore, outer diameter, and thickness of these flanged bearings?

A: The standard dimensions are: Inner bore: 6 mm, Outer diameter: 19 mm, Thickness: 6 mm. Please cross-reference these measurements with your application requirements before ordering.

Q: Do these bearings come pre-lubricated?

A: Yes. The double-shield (ZZ) design means these bearings are pre-greased at the factory and sealed to retain lubrication over time — minimizing maintenance and extending service life in most standard applications.
