6307 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Bearings
The 6307 deep groove ball bearing is a high-strength medium-large size model in the 6300 series, equipped with enlarged rolling bodies and thickened reinforced raceway to achieve higher load capacity and structural rigidity than standard bearings. This single-row deep groove ball bearing provides excellent radial and axial load-bearing performance, superior anti-fatigue stability and low-friction rotation, supporting long-term low-noise, high-speed operation under continuous medium and heavy cyclic loads. As a core rotary component for industrial mechanical transmission systems, the 6307 bearing balances stable high-speed performance and heavy-load durability. It is available in three mainstream configurations: open type, 6307ZZ double metal shield type and 6307-2RS double rubber sealed type, with five industrial-grade material options to adapt to economic, sanitary, wear-resistant and corrosive industrial working conditions.
6307 Open / ZZ / 2RS Structural Features
6307 Open Type: The unsealed open structure delivers unobstructed air circulation and efficient heat dissipation, effectively avoiding heat accumulation during long-duration high-speed operation. It allows convenient grease replacement and simple routine maintenance without increasing rotational resistance. Suitable for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and consistent performance under long-cycle heavy-load operation.
6307ZZ Double Metal Shields: Featured with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks dry fine dust, floating micro particles and workshop debris. The non-contact design retains original high-speed precision and smooth rotation with minimal friction loss. With reliable durability and high cost performance, 6307ZZ bearings are widely used in dry automated production lines, medium-large industrial motors, power transmission systems and general heavy electromechanical equipment.
6307-2RS Double Rubber Seals: This fully sealed version adopts double-sided contact rubber seals to isolate moisture, splash water, oil mist and corrosive dust comprehensively. It locks internal lubricating grease firmly to prevent leakage and aging, realizing long-term maintenance-free operation. It is ideal for humid, dusty and outdoor harsh working environments for industrial precision machinery.
6307 Bearing Material Performance
Carbon Steel: High cost-effective industrial standard material with uniform hardness and stable anti-fatigue performance. It offers reliable wear resistance and smooth high-speed rotation for medium and heavy-duty machinery, serving as the best choice for mass industrial and commercial economical 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, widely applied in food processing machinery, sanitary production equipment and daily precision mechanical devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands mild chemical erosion and coastal high humidity conditions, perfect for marine auxiliary equipment, sanitary processing machines and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel combining moderate corrosion resistance and high surface hardness. It delivers outstanding wear and impact resistance, ensuring stable dimensional accuracy during long-term heavy-load cyclic operation.
440 Stainless Steel: Ultra-high hardness stainless steel with superior abrasion resistance and structural stability. It maintains precise operation under severe wear and complex corrosive environments, customized for high-end heavy-duty industrial precision equipment.
Core Advantages And Industrial Applications
The 6307 deep groove ball bearing features excellent heavy-load capacity, high structural rigidity, ultra-low noise and durable high-speed stability. Three professional sealing structures and five material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively used in industrial heavy-duty drive motors, automation transmission systems, engineering auxiliary machinery, precision testing instruments, food processing equipment, medical devices and outdoor industrial facilities, providing stable, low-maintenance and high-efficiency precision rotation solutions for modern medium and heavy-duty mechanical systems.
