Product Q&A

Q:What makes the 674 miniature ball bearing suitable for instrumentation?

The 674 thin section bearing (4x7x2.5mm) is designed with an ultra-compact profile, low friction torque, and ABEC-5 high precision. This ensures smooth, vibration-free rotation, which is critical for precision medical instruments and aerospace devices.

Q:Can Welink Bearing customize the 674 bearing for high-speed micro motors?

Yes. As a direct manufacturer, we offer customized solutions for 674 bearings, including specific radial clearances (like C3), high-speed grease options (up to 50,000 RPM), and specialized cage materials to perfectly match your micro motor requirements.

Q:What are the differences between 674-ZZ, 674-2RS, and open type bearings?

The open 674 (4x7x2mm) is ideal for oil-lubricated enclosed spaces. The 674-ZZ (metal shields) offers low friction for high speeds, while the 674-2RS (rubber seals) provides maximum protection against dust and moisture. Both shielded and sealed versions have a 2.5mm width.

Q:Are your miniature deep groove ball bearings RoHS and REACH compliant?

Absolutely. All our bearings, including the 674 series, are manufactured from premium GCr15 steel or stainless steel and come with full ISO 9001:2015, RoHS, and REACH certifications, ensuring safe and compliant export to global markets.
