F623 2rs Bearing Product Overview & Core Advantages

The F623 2rs is a metric miniature ball bearing engineered for compact applications demanding reliable performance. This single row, sealed bearing is designed primarily for radial loads and offers a robust solution in a minimal footprint. Its key advantages include a high limiting speed of 50,000 rpm and a sealed construction that protects against contamination, ensuring long service life and consistent operation in demanding environments. Manufactured from high-grade chrome steel with a stainless steel cage, it provides excellent durability and corrosion resistance, making it an ideal choice for high-precision, high-reliability applications where space is at a premium.

F623 2rs Bearing Model Code Explained, Specifications & Naming Convention

Model Segment Technical Meaning
F623 Denotes the bearing series and size. "F" often indicates a flanged design, with a 3mm bore, 10mm outside diameter, and 4mm width.
2RS Signifies that the bearing is equipped with two rubber seals (RS), one on each side. This provides superior protection against dust, moisture, and other contaminants, helping to retain lubrication and extend bearing life.

F623 2rs Bearing Structural Features & Performance Benefits

  • Compact & Flanged Design: The integral flange (11.5mm outer diameter) simplifies mounting and positioning, providing excellent axial location and stability within the housing, which is critical for miniature applications.
  • Robust Load Capacity: With a dynamic load rating of 121 lbf and a static load rating of 39 lbf, this bearing is capable of handling significant radial loads for its size, ensuring reliable performance under stress.
  • High-Speed Capability: The combination of a stainless steel cage, seven precision balls, and an ABEC1 tolerance class enables a high limiting speed of 50,000 rpm, making it suitable for high-speed spindles and motors.
  • Sealed & Protected: The double rubber seals (2RS) effectively shield the internal components from contaminants. This design retains the required lubrication, reduces maintenance needs, and allows for operation in a wide temperature range from -30°C to 110°C.
  • Precision Internal Clearance: The specified radial internal clearance (MC3 group: 0.002mm to 0.013mm) ensures smooth, low-noise, and low-vibration operation, which is essential for sensitive electronic and precision equipment.

F623 2rs Bearing Typical Application Areas

  • Small Electric Motors: Ideal for brushless DC motors, stepper motors, and cooling fans where high speed and compact size are paramount.
  • Precision Instruments: Used in optical encoders, medical devices, and laboratory equipment that require smooth, reliable, and quiet rotational motion.
  • Office Automation & IT Equipment: Commonly found in printers, scanners, and hard disk drives.
  • Robotics & RC Models: Suitable for joints, gears, and small drives in robotic arms, drones, and hobbyist models due to their light weight (1.85 g) and high performance.
  • Small Power Tools & Pumps: Applicable in miniature drills, grinders, and small fluid pumps that operate at high speeds.
