6913 Deep Groove Ball Bearing | Open, ZZ, 2RS Ultra-Thin Precision Bearings
The 6913 deep groove ball bearing is a high-performance ultra-thin precision part in the 6900 series, adopting reinforced raceway design and optimized rolling element arrangement to improve structural rigidity and steady medium-load capacity. Designed for ultra-compact, space-restricted installation scenarios, this single-row thin-wall bearing delivers low-friction smooth rotation, outstanding dimensional consistency and excellent anti-fatigue performance. It supports long-term ultra-quiet, high-speed cyclic continuous operation, widely used as a core rotary component for medium-sized miniaturized electromechanical equipment and industrial precision transmission systems. The 6913 series covers three classic industrial versions: open type, 6913ZZ double metal shield type and 6913-2RS double rubber sealed type, with five industrial-grade material options to adapt to economical, sanitary, wear-resistant and corrosive complex working conditions.
6913 Open / ZZ / 2RS Structural Features
6913 Open Type: The unsealed open structure achieves unobstructed air circulation and efficient heat dissipation, effectively avoiding heat accumulation during long-duration high-speed operation. It allows tool-free grease refilling and convenient daily maintenance without extra rotational resistance. Suitable for clean, dry indoor environments and fully enclosed precision equipment, it maintains stable running accuracy and consistent performance during long-cycle medium-load operation.
6913ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof precision bearing effectively blocks dry fine dust, floating micro particles and industrial debris. The non-contact protective structure retains original high-speed precision and rotational smoothness with minimal friction loss. Featuring stable durability and excellent cost performance, 6913ZZ bearings are widely applied in dry high-speed miniature motors, precision consumer electronics, automated micro components and compact industrial transmission systems.
6913-2RS Double Rubber Seals: This fully sealed model adopts double-sided contact rubber seals to fully isolate moisture, water splashes, oil mist and corrosive fine dust. It firmly locks internal lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. It stably adapts to humid, dusty and mildly harsh working environments for outdoor and industrial high-precision electromechanical devices.
6913 Bearing Material Performance
Carbon Steel: Cost-effective standard industrial material with uniform hardness and stable anti-fatigue ability. It provides reliable wear resistance and smooth high-speed rotation for conventional precision equipment, delivering excellent cost efficiency for mass electronic and industrial batch production applications.
304 Stainless Steel: Food-grade stainless steel with superior anti-oxidation and anti-rust properties. It resists surface corrosion and precision degradation in humid and open environments, ideal for food processing machinery, sanitary equipment and daily precision electromechanical devices.
316 Stainless Steel: Marine-grade corrosion-resistant material with strong resistance to acid, alkali and salt spray. It withstands mild chemical corrosion and coastal high humidity, perfect for marine precision parts, sanitary instruments and chemical processing equipment.
420 Stainless Steel: High-toughness martensitic stainless steel that balances moderate corrosion resistance and high surface hardness. It offers stable wear and impact resistance, maintaining accurate dimensional stability during long-term continuous high-speed operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It maintains precise and stable operation under severe wear and corrosive conditions, tailored for high-end ultra-thin precision industrial equipment.
Core Advantages And Industrial Applications
