6803 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6803 deep groove ball bearing is a high-precision ultra-thin component in the 6800 series, featuring an ultra-slim cross-section and optimized low-friction raceway design. Different from standard thin-wall bearings, the 6803 model provides extreme space-saving installation while retaining excellent rotational stability and anti-fatigue performance. It supports long-term ultra-quiet, high-speed operation under light and medium loads, making it an ideal compact rotary solution for miniaturized and space-constrained precision machinery. The 6803 series comes with three mainstream industrial configurations: open type, 6803ZZ double metal shield type and 6803-2RS double rubber sealed type. Five industrial-grade material options fully adapt to economic, sanitary, wear-resistant and corrosive working environments for diverse precision applications.
6803 Open / ZZ / 2RS Structural Features
6803 Open Type: The unsealed open structure ensures unobstructed airflow and rapid heat dissipation, effectively preventing heat accumulation during continuous high-speed operation. It allows straightforward grease replenishment and daily maintenance without increasing rotational resistance. Designed for clean, dry indoor environments and fully enclosed precision devices, it maintains stable accuracy and consistent performance during long-cycle light-load operation.
6803ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof precision bearing effectively blocks fine dry dust, micro debris and floating particles. The non-contact structure preserves original high-speed precision and smooth rotation with minimal friction loss. Featuring reliable durability and excellent cost performance, 6803ZZ bearings are widely used in dry automation equipment, miniature drive motors, consumer electronics and compact precision transmission systems.
6803-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to isolate moisture, splash water, oil mist and corrosive fine dust. It tightly locks internal lubrication grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh working conditions for portable and outdoor precision electromechanical devices.
6803 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 precision equipment, offering optimal cost efficiency for mass consumer and industrial batch applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It prevents surface corrosion and precision degradation in humid environments, suitable for food processing micro equipment, sanitary machinery and daily precision devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with excellent acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal humidity, ideal for marine precision accessories, sanitary processing equipment and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel balancing moderate corrosion resistance and high hardness. It features stable wear and impact resistance, maintaining precise dimensional accuracy during continuous high-speed operation.
440 Stainless Steel: Ultra-high hardness stainless steel with outstanding abrasion resistance. It sustains stable and accurate operation under severe wear and corrosive conditions, customized for high-end ultra-thin precision industrial and electronic equipment.
Core Advantages And Industrial Applications
The 6803 deep groove ball bearing features an ultra-thin lightweight structure, space-saving installation, ultra-low noise and consistent high-speed precision performance. Three sealing options and five material grades cover economic, anti-rust, wear-resistant and anti-corrosion application scenarios. It is extensively applied in miniature precision motors, smart wearable devices, consumer electronics, small household appliances, miniature medical equipment, automated precision components and light-duty food processing machinery, providing compact, low-noise and long-lasting precision rotation solutions for modern miniaturized mechanical systems.
