Frequently Asked Questions
Q: What is the difference between ZZ and 2RS mini ball bearings?
A: ZZ bearings feature metal shields on both sides, making them ideal for high-speed applications where heat dissipation is important. 2RS bearings have rubber seals on both sides, providing better protection against moisture, dust, and contaminants — great for outdoor or dusty environments.
Q: Which bearing model number should I choose for my project?
A: The model number indicates the bearing's inner diameter, outer diameter, and width. For example, 692 (2×6×3mm), 696 (6×15×5mm), and 699 (9×20×6mm) are popular choices. Check your equipment's specification sheet or measure the existing bearing to select the right size from the 682–699 series.
Q: Are these mini ball bearings suitable for 3D printers and RC vehicles?
A: Yes! JARBLUE mini ball bearings are widely used in 3D printers, RC cars, drones, and robotic builds due to their compact size, precision tolerances, and durable bearing steel construction. The 10-piece pack is perfect for stocking spares or completing a full build.
