6713 Deep Groove Ball Bearing | Open, ZZ, 2RS Thin-Wall Precision Bearings
The 6713 deep groove ball bearing is a large-bore heavy-duty thin-wall precision component in the 6700 series, engineered with thickened raceways and upgraded rolling elements to maximize structural rigidity and medium-heavy load capacity. Retaining the series’ signature ultra-slim lightweight profile, this single-row bearing solves strict space-limited installation requirements for modern compact precision machinery while delivering exceptional anti-fatigue stability and low-friction rotational performance. It supports long-term continuous low-noise, high-speed operation under stable medium-heavy cyclic loads, serving as a critical core rotary part for high-precision automation and compact electromechanical systems. The 6713 series includes three mainstream industrial configurations: open type, 6713ZZ double metal shield type and 6713-2RS double rubber sealed type, with five industrial-grade materials to adapt to economical, sanitary, wear-resistant and corrosive complex working environments.
6713 Open / ZZ / 2RS Structural Features
6713 Open Type: The unsealed open structure enables unobstructed air circulation and efficient heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed operation. It allows fast grease replacement and hassle-free daily maintenance without generating extra rotational resistance. Designed for clean, dry indoor workshops and fully enclosed slim precision equipment, it maintains stable running accuracy and consistent performance during long-cycle medium-heavy load operation.
6713ZZ 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 workshop debris. The non-contact design preserves original high-speed precision and rotational smoothness with minimal friction loss. Featuring reliable long-term durability and superior cost performance, 6713ZZ bearings are widely applied in dry precision automation systems, slim high-power drive motors, precision electronic devices and compact heavy-duty transmission equipment.
6713-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, splash water, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, realizing long-term maintenance-free operation. It perfectly adapts to humid, dusty and mildly harsh outdoor working conditions for compact high-precision electromechanical equipment.
6713 Bearing Material Performance
Carbon Steel: High cost-performance standard industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for conventional medium-heavy load precision equipment, providing optimal cost efficiency for mass electronic products and general industrial 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, suitable for food processing micro equipment, sanitary machinery and daily slim precision devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands mild chemical erosion and coastal high 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 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 complex corrosive environments, customized for high-end industrial and electronic slim precision equipment.
