6216 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Bearings
The 6216 deep groove ball bearing is a large-size heavy-duty precision model in the 6200 series, engineered with enlarged rolling elements and fully thickened raceway structure for maximized load capacity and structural rigidity. This single-row deep groove ball bearing delivers exceptional radial and axial load resistance, outstanding anti-fatigue performance and stable dimensional consistency during long-term high-speed, heavy-cycle operation. Designed for large-scale industrial mechanical systems, it balances heavy-load bearing capacity, low-friction rotation and extended service life. The 6216 series is available in three standard configurations: open type, 6216ZZ double metal shield type and 6216-2RS double rubber sealed type, with five industrial-grade materials to accommodate economical, sanitary, high-wear and corrosive industrial working conditions.
6216 Open / ZZ / 2RS Structural Features
6216 Open Type: Featuring an unsealed open structure, this bearing supports unrestricted air circulation and efficient heat dissipation to avoid thermal accumulation during continuous high-speed operation. It allows quick grease replacement and hassle-free routine maintenance without creating extra rotational resistance. Ideal for clean, dry indoor workshops and fully enclosed large precision machinery, it maintains stable running accuracy and consistent performance under prolonged heavy-load operation.
6216ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks fine dry dust, floating micro particles and workshop debris. The non-contact design preserves original high-speed stability and rotational smoothness with minimal friction loss. Offering excellent durability and cost efficiency, 6216ZZ bearings are widely applied in dry automated production lines, large industrial motors, heavy-duty transmission systems and general electromechanical equipment.
6216-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to achieve comprehensive isolation from moisture, splash water, oil mist and corrosive dust. It securely locks internal lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. It perfectly adapts to humid, dusty, splash-prone and harsh outdoor industrial environments.
6216 Bearing Material Performance
Carbon Steel: High cost-performance industrial standard material with uniform hardness and reliable anti-fatigue properties. It delivers stable wear resistance and smooth high-speed rotation for heavy-duty machinery, making it the optimal choice for mass industrial and commercial economical applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid and open environments, suitable for food processing machinery, light industry and sanitary precision equipment.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with excellent acid, alkali and salt spray tolerance. It withstands chemical erosion and coastal high humidity conditions, ideal for marine equipment, sanitary processing machines and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel with balanced corrosion resistance and high surface hardness. It features outstanding wear and impact resistance, maintaining stable dimensional accuracy during long-cycle heavy-load continuous operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains precise and stable operation under severe wear and complex corrosive conditions, customized for high-end heavy-duty industrial precision systems.
Core Advantages And Industrial Applications
The 6216 deep groove ball bearing features premium heavy-load capacity, ultra-high structural stability, low noise and long-lasting high-speed performance. Three diversified sealing structures and five professional material grades fully cover economical, rust-proof, wear-resistant and anti-corrosion industrial scenarios. It is extensively used in large industrial heavy-duty motors, automated transmission systems, engineering machinery, precision instruments, food processing equipment, medical devices and outdoor industrial facilities, providing stable, low-maintenance and high-efficiency precision rotation solutions for large heavy-duty mechanical systems.
