62201 Deep Groove Ball Bearings

62201 Deep Groove Ball Bearing | Open, ZZ, 2RS High Load Bearings

The 62201 deep groove ball bearing is a thickened, high-load precision component featuring a widened ball groove design, optimized for higher radial load capacity compared to standard thin-wall bearings. Engineered with enhanced structural rigidity and stable anti-fatigue performance, this single-row bearing supports long-term high-speed, ultra-quiet continuous operation under medium-heavy loads. Tailored for compact mechanical systems requiring greater load-bearing performance in limited installation space, the 62201 series covers three mainstream industrial configurations: open type, 62201ZZ double metal shield type and 62201-2RS double rubber sealed type. Available in five industrial-grade materials, it adapts to economical, sanitary, high-wear and corrosive industrial working environments for diversified precision mechanical applications.

62201 Open / ZZ / 2RS Structural Features

62201 Open Type: The unsealed open structure delivers unobstructed air circulation and excellent heat dissipation, effectively eliminating thermal accumulation during prolonged high-speed and high-load operation. It allows tool-free grease replenishment and simple routine maintenance without extra rotational resistance. Ideal for clean, dry indoor industrial environments and fully enclosed precision machinery, it maintains stable running accuracy and consistent performance during long-cycle heavy-load operation.

62201ZZ 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 protective structure preserves original high-speed precision and rotational smoothness with minimal friction loss. Combining durable service life and outstanding cost performance, 62201ZZ bearings are widely applied in industrial micro motors, transmission equipment, precision automation components and dry operational mechanical systems.

62201-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals to comprehensively isolate moisture, water splashes, oil mist and corrosive fine dust. It tightly locks internal lubricating grease to prevent leakage, oxidation and aging, enabling long-term maintenance-free operation. It stably adapts to humid, dusty and mildly harsh working conditions for outdoor, portable and industrial heavy-duty precision electromechanical equipment.

62201 Bearing Material Performance

Carbon Steel: High cost-performance industrial base material with uniform hardness and stable anti-fatigue properties. It provides reliable wear resistance and smooth high-speed rotation for conventional mechanical equipment, ensuring stable operation for mass industrial batch applications with superior cost efficiency.

304 Stainless Steel: Food-grade stainless steel with excellent oxidation and rust resistance. It avoids micro corrosion and precision degradation in humid and open environments, perfectly suited 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 erosion and coastal high humidity, ideal for marine precision parts, sanitary instruments and chemical processing miniature equipment.

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 high-load 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 corrosive conditions, customized for high-end industrial precision mechanical systems.
