636 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Mini Bearings
The 636 deep groove ball bearing is a high-precision miniature component in the 6300 series, featuring optimized raceway geometry and upgraded rolling element configuration for enhanced stability and low-friction operation. This single-row deep groove ball bearing delivers ultra-quiet, consistent high-speed performance and reliable anti-fatigue durability under long-term light cyclic loads. Compact in size and lightweight in structure, it serves as an essential rotary part for mini precision electromechanical systems. The 636 series comes in three standard configurations: open type, 636ZZ double metal shield type and 636-2RS double rubber sealed type, with five industrial-grade material options to suit economical, sanitary, wear-resistant and corrosive working environments for diverse miniature industrial applications.
636 Open / ZZ / 2RS Structural Features
636 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation during continuous high-speed operation. It allows easy grease replacement and routine cleaning without adding extra rotational resistance. Suited for clean, dry indoor workshops and fully enclosed precision micro machinery, it maintains stable running accuracy and long-term operational consistency under light-load cyclic working conditions.
636ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks fine dry dust, tiny floating particles and micro workshop debris. The non-contact design preserves original high-speed precision and rotational smoothness with zero friction loss. Offering reliable durability and excellent cost performance, 636ZZ bearings are widely used in dry micro automation equipment, small DC motors, precision electronic devices and general miniature transmission systems.
636-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, splash water, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage and aging, enabling long-term maintenance-free operation. It perfectly adapts to humid, dusty and mild outdoor working scenarios for miniature precision mechanical equipment.
636 Bearing Material Performance
Carbon Steel: Cost-effective standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for conventional light-load miniature equipment, providing outstanding cost performance for mass consumer electronics and general industrial applications.
304 Stainless Steel: Food-grade stainless steel with excellent oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, ideal for food processing micro devices, light industry and daily precision miniature machinery.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high humidity conditions, suitable for sanitary miniature equipment, marine micro devices and light chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high surface hardness. It features stable wear and impact resistance, maintaining accurate dimensional stability during long-cycle continuous operation of miniature precision parts.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance and structural stability. It sustains precise and stable operation under slight wear and complex corrosive environments, customized for high-end electronic and industrial precision miniature equipment.
Core Advantages And Industrial Applications
The 636 deep groove ball bearing features ultra-compact footprint, lightweight design, ultra-low noise and stable high-speed performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion miniature application scenarios. It is extensively applied in micro drive motors, precision instruments, consumer electronics, intelligent equipment accessories, small household appliances, miniature medical devices, automated precision components and food processing micro machinery, providing durable, low-maintenance and high-efficiency precision rotation solutions for modern light-load miniature mechanical systems.
