7002 Angular Contact Ball Bearing | Compact High-Speed Precision Bearings
The 7002 angular contact ball bearing is a compact single-row precision bearing in the 7000 series, specially engineered for light-load, ultra-smooth and continuous high-speed mechanical operation. Different from higher-load 7003 models, the 7002 variant features a streamlined internal structure with optimized clearance design, perfectly balancing low friction and precise load bearing. It supports combined radial and single-direction axial loads, delivering outstanding rotational stability and minimal runout. With customizable sealing solutions and multi-grade material options, this compact bearing adapts to diverse light industrial and precision mechanical scenarios.
Available Sealing Types And Working Characteristics
7002 angular contact bearings come with three practical sealing configurations to suit different environmental conditions, ensuring stable operation and extended service lifespan:
Open Type: No protective seals, featuring unobstructed heat dissipation and ultra-low rolling resistance. It supports external circulating lubrication and regular grease replenishment, ideal for clean laboratory environments and high-precision high-speed equipment requiring strict heat control.
ZZ Metal Shield Type: Dual-sided non-contact metal shields that block dry dust and solid particles without compromising speed performance. With low operational resistance and no grease leakage, it is the optimal choice for dry indoor workshops and continuous-running light-duty automation equipment.
2RS Rubber Sealed Type: Double-sided contact rubber seals with excellent barrier performance. It effectively resists moisture, fine dust, oil contamination and mild corrosive substances, realizing long-term maintenance-free operation, suitable for variable and complex workshop environments.
Bearing Material Options And Matching Applications
Chrome Bearing Steel: Standard industrial-grade material with fine grain structure, offering excellent anti-fatigue performance and stable hardness under high-speed rotation. It maintains long-term precision with high cost performance, widely used in small precision motors, miniature machine tool parts, fan rotors and general light-load transmission equipment.
304 Stainless Steel: Features superior atmospheric rust resistance and oxidation stability, adapting to humid and dusty daily working environments. It is a budget-friendly anti-corrosion solution for civilian precision equipment, light automated devices and indoor electromechanical assemblies.
420 Stainless Steel: Integrates hardness and mechanical toughness, resisting frequent start-stop friction and weak chemical erosion. It guarantees consistent precision rotation, ideal for optical instruments, detection equipment and portable precision machinery.
440C Stainless Steel: High-hardness abrasion-resistant material with strong durability in damp and lightly corrosive environments, effectively preventing premature wear and precision failure for long-cycle automated equipment.
316 Stainless Steel: Premium corrosion-resistant material with excellent salt spray and acid-base resistance, applicable for food processing auxiliary equipment, marine miniature accessories and chemical precision testing devices.
Product Strengths And Industrial Applications
The 7002 angular contact ball bearing stands out for its compact size, ultra-low vibration, precise rotation and stable high-speed performance. Its flexible sealing and material customization enable strong environmental adaptability for light-load precision scenarios. Commonly utilized in precision automation components, optical equipment, small power machinery, instrumentation and light industrial transmission systems, it provides reliable, high-efficiency and cost-effective precision bearing support for various compact high-speed mechanical systems.
