6815 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6815 deep groove ball bearing is a top-tier super-large bore ultra-thin precision component in the 6800 series, designed with fully thickened raceway grooves and upgraded oversized rolling elements to maximize structural rigidity and heavy-load bearing capacity. It retains the series’ signature ultra-slim lightweight profile, perfectly solving extreme space-limited installation challenges for large compact precision mechanical systems. Optimized for long-cycle operation, this single-row thin-wall bearing delivers stable low-friction rotation, outstanding anti-fatigue performance and consistent dimensional accuracy, supporting continuous ultra-quiet, high-speed operation under heavy cyclic loads. The 6815 series offers three standard industrial sealing configurations: open type, 6815ZZ double metal shield type and 6815-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive complex industrial environments.
6815 Open / ZZ / 2RS Structural Features
6815 Open Type: The unsealed open structure features unobstructed air circulation and efficient heat dissipation, completely avoiding thermal accumulation during prolonged high-speed continuous operation. It enables fast grease replenishment and tool-free routine maintenance without increasing extra rotational resistance. Suitable for clean, dry indoor workshops and fully enclosed large slim precision equipment, it maintains stable running accuracy and consistent performance during long-term heavy-load operation.
6815ZZ Double Metal Shields: Fitted with dual-sided non-contact steel shields, this premium dust-proof bearing effectively blocks fine dry dust, floating micro particles and industrial debris. The non-contact protective design preserves original high-speed precision and rotational smoothness with minimal friction loss. Boasting exceptional long-term durability and superior cost performance, 6815ZZ bearings are widely deployed in dry precision automation systems, large slim high-power motors, precision electronic devices and compact heavy-duty transmission machinery.
6815-2RS Double Rubber Seals: This fully sealed high-end variant adopts double-sided contact rubber seals to comprehensively isolate moisture, splash water, oil mist and corrosive fine dust. It firmly locks internal lubricating grease to prevent leakage, oxidation and aging, achieving long-term maintenance-free operation. It reliably adapts to humid, dusty and mildly harsh workshop and outdoor working conditions for large-scale compact high-precision electromechanical equipment.
6815 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 heavy-load precision equipment, providing optimal cost efficiency for mass industrial and electronic batch 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 machinery, sanitary equipment and slim precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high humidity, perfect for marine precision parts, sanitary processing equipment and 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-term continuous precision operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains precise, stable operation under severe wear and corrosive environments, customized for high-end ultra-thin precision industrial equipment.
Core Advantages And Industrial Applications
The 6815 deep groove ball bearing integrates an ultra-thin space-saving structure, lightweight design, supreme heavy-load capacity, ultra-low noise and long-lasting high-speed stability. Three versatile sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion precision application scenarios. It is widely applied in large slim high-power precision motors, industrial automation transmission systems, smart mechanical components, high-end consumer electronics, miniature medical devices and food processing machinery, providing compact, low-maintenance and high-efficiency precision rotation solutions for modern space-limited heavy-duty precision mechanical systems.
