Where the 625 Bearing is Commonly Used:

Due to its small size and precision, the 625 bearing is typically used in applications that require low friction, compact design, and moderate speed. Here are some common uses:

1. Electric Motors and Tools

• Small DC motors (used in fans, drones, hobby electronics)
• Rotary tools (like Dremels)
• Compact power tools

2. 3D Printers and CNC Machines

• Linear motion components (e.g., rollers, guide rails)
• Stepper motor support
• Filament feed mechanisms

3. Robotics and Hobby Electronics

• Robot wheel hubs
• Arm joint pivots
• Gearboxes and drive systems

4. Skate Equipment

• Mini scooters or skate bearings (less common than standard 608)
• Some inline skates with specialized requirements

5. Office Equipment

• Printers and scanners (for carriage movement and rollers)
• Small fans

6. Medical Devices

• Dental tools
• Small motor-driven pumps or instruments

Variants and Materials

• 625ZZ: Shielded on both sides (for dust protection)
• 625-2RS: Sealed on both sides (for better protection against moisture/dirt)
