FR144 Miniature Flanged Deep Groove Ball Bearing 1/8″x1/4″x7/64″ for RC Models Robotics

製品概要

When designing miniature machinery and high-precision equipment, every component must justify its place—and the FR144 miniature flanged deep groove ball bearing more than earns its keep. The FR144 is an inch?series flanged miniature bearing with a 1/8″ (3.175 mm) bore, 1/4″ (6.35 mm) outer diameter, and a slim width of just 2.38 mm (3/32″) or 2.779 mm (7/64″) for shielded variants.

主な特長:

• Ultra-Compact
  With its 1/8″ bore and 1/4″ outer diameter, the FR144 is specifically designed for inch-based miniature mechanisms. This exceptionally compact geometry enables use in the tightest assemblies—RC car gearboxes, micro motor housings, 3D printer print heads, and medical device actuators—where larger bearings simply cannot fit.

• High Speed
  The FR144’s precision ground raceways, high-quality balls, and optimized internal geometry deliver outstanding high-speed performance. This speed capability makes the FR144 suitable for high-speed micro motors, dental handpieces, turbochargers, and other applications where rotational velocity is critical.

• Multi-Variant Flexibility
  クロム鋼, Stainless Steel, and Hybrid Ceramic — The FR144 platform offers multiple material configurations to match your specific operating environment.
• スムーズ, 静かな, Low-Vibration Operation
  The FR144’s deep groove geometry ensures smooth ball guidance, efficient load distribution, and minimal vibration. Precision ground raceways and quality balls result in quiet, consistent rotation with excellent radial and axial runout characteristics. For applications that demand the lowest possible noise, the Z4 vibration grade variant (SFR144ZZ) offers ultra-quiet performance.
