Product Q&A

Q:What are the exact dimensions and load capacity of the 629 deep groove ball bearing?

The 629 bearing features a precise 9mm inner diameter, 26mm outer diameter, and 8mm width. It offers a dynamic load rating of 4.60 kN and a static load rating of 1.97 kN, designed for stable, lightweight load distribution.

Q:Is the 629 bearing suitable for high-speed RC models and 3D printers?

Yes, absolutely. With high-precision manufacturing and an operational limit speed of up to 32,000 RPM (grease lubricated), it provides the low friction and high stability required for 3D printer extruders and RC car/drone components.

Q:Can Welink Bearing provide custom seals or clearance specifications for bulk orders?

Yes, we offer full OEM/ODM customization. You can choose specific seal types (such as 2RS rubber or ZZ metal shields) and internal clearances (like C3) to match your exact environmental and operational needs.
