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

产品概述

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 毫米) bore, 1/4″ (6.35 毫米) 外径, and a slim width of just 2.38 毫米 (3/32″) or 2.779 毫米 (7/64″) for shielded variants.

主要特点:

• Ultra-Compact
  With its 1/8″ bore and 1/4″ 外径, 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.

• 高速
  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
  Chrome Steel, Stainless Steel, and Hybrid Ceramic — The FR144 platform offers multiple material configurations to match your specific operating environment.
• 光滑的, Quiet, 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.
