FR10 Flange Ball Bearings

FR10 Flange Deep Groove Bearing | Open, ZZ, 2RS High Precision Miniature Bearing

The FR10 flange deep groove ball bearing is a heavy-duty miniature flange bearing designed for compact micro mechanical systems requiring larger inner diameter, higher radial load capacity and stable long-term high-speed operation. Adopting a thickened one-piece flange and high-precision polished raceway structure, this bearing delivers excellent rigidity, ultra-low vibration and consistent rotary stability during continuous cyclic work. The integrated flange eliminates extra positioning hardware, streamlines assembly processes, and effectively prevents shaft offset and axial play in space-constrained precision equipment layouts. Available in three mainstream industrial versions: FR10 open type, FR10ZZ double metal shield type and FR10-2RS double rubber sealed type, it reliably operates in dry, dusty, humid and mildly corrosive indoor and outdoor environments. Supplied in carbon steel, 304 stainless steel, 316 stainless steel, 420 stainless steel and 440 stainless steel, the FR10 covers full-spectrum industrial needs for economical, sanitary, wear-resistant and anti-corrosion miniature precision applications.

FR10 Open / ZZ / 2RS Structural Features

FR10 Open Type: The open unsealed structure allows unobstructed air flow and rapid heat dissipation, effectively avoiding thermal saturation and precision drop during prolonged high-load high-speed operation. It supports easy grease replenishment and tool-free daily maintenance without increasing rotational resistance. Perfect for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and long-cycle operational consistency.

FR10ZZ Double Metal Shields: Equipped with dual non-contact steel shields, the FR10ZZ efficiently blocks dry fine dust, floating particles and micro industrial debris. The non-contact protective design retains original high-speed smoothness with minimal friction loss, ensuring stable high-precision operation. Featuring outstanding durability and cost performance, this model is widely used in dry industrial environments and long-running miniature automation equipment.

FR10-2RS Double Rubber Seals: The fully sealed 2RS structure adopts double-sided contact rubber seals to isolate moisture, water splashes, oil mist and corrosive particles. It locks internal lubricant firmly to prevent grease leakage, oxidation and aging, achieving long-term maintenance-free performance for humid, dusty and complex working scenarios.

FR10 Bearing Material Performance

Carbon Steel: High cost-effective industrial material with uniform hardness and stable anti-fatigue performance. Carbon steel FR10 bearings offer reliable wear resistance and smooth rotation, ideal for mass production and budget-sensitive miniature automation projects.

304 Stainless Steel: Food-grade rust-proof stainless steel with excellent oxidation resistance. It withstands mild humid corrosion, suitable for food processing equipment, medical devices and sanitary-grade precision mechanical systems.

The FR10 miniature flange bearing features a thickened reinforced structure, upgraded heavy-load capacity, integrated flange positioning, ultra-quiet operation and durable high-speed stability. Multiple sealing types and diverse material grades fully meet industrial requirements for cost efficiency, sanitation, wear resistance and corrosion protection. Widely applied in medium-load miniature motors, large-size drone precision assemblies, robotic micro transmission joints, optical detection instruments, micro transmission systems, high-precision power tools and medical automation equipment, the FR10 acts as a core rotary and positioning component for compact space-limited mechanical structures. It delivers low-noise, high-efficiency and low-maintenance precision rotation solutions for modern industrial, commercial and sanitary miniaturized automation devices.
