607 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Miniature Bearings
The 607 deep groove ball bearing is a high-performance miniature single-row bearing optimized for high-speed precision micro mechanical systems. As an upgraded model of the 606 bearing, it features a larger inner diameter, expanded rolling elements and enhanced structural rigidity, delivering higher load capacity and better running stability while retaining a compact lightweight design. Capable of bearing rated radial loads and auxiliary axial loads, it supports long-term low-noise, low-friction continuous operation. The 607 series offers three mainstream structural versions: open type, 607ZZ double metal shield type and 607-2RS double rubber sealed type, paired with five industrial-grade materials to meet diverse ordinary, sanitary and corrosive working scenarios.
607 Open / ZZ / 2RS Structural Features
607 Open Type: Adopting a fully open unsealed structure, this basic model features unobstructed heat dissipation and smooth lubricant circulation. It allows quick grease replacement and effortless daily maintenance without extra rotational resistance. It is widely used in clean, dry indoor environments and fully enclosed precision equipment, delivering consistent high-speed precision operation under regular maintenance cycles.
607ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this professional dust-proof structure effectively blocks fine dust, floating particles and dry workshop debris. The non-contact design preserves original high-speed performance and rotational accuracy with zero friction loss. Featuring high durability and cost efficiency, it is the ideal choice for dry production lines, miniature automation and general precision transmission equipment.
607-2RS Double Rubber Seals: Designed with double-sided contact rubber seals, this fully sealed variant provides full protection against moisture, splash water, oil dirt and corrosive fine particles. It effectively locks internal lubricating grease to avoid leakage and contamination, achieving long-term maintenance-free operation. It perfectly adapts to outdoor, humid and dusty harsh working conditions with strong environmental adaptability.
607 Bearing Material Specifications
Carbon Steel: Standard economical industrial material with uniform hardness and excellent anti-fatigue performance. It ensures stable high-speed operation and wear resistance for general micro equipment, featuring low cost and high practicability for mass civilian and industrial applications.
304 Stainless Steel: Universal anti-rust grade with outstanding atmospheric oxidation resistance. It prevents surface rust and precision degradation in humid and open environments, suitable for light industry, outdoor micro devices and conventional food-grade equipment.
316 Stainless Steel: Premium marine-grade corrosion-resistant material. It offers superior acid, alkali and salt spray resistance, tolerating mild chemical corrosion and coastal high-humidity environments for sanitary and marine precision equipment.
420 Stainless Steel: Martensitic high-toughness stainless steel that balances moderate corrosion resistance and high hardness. It delivers excellent wear and impact resistance, ideal for high-precision moving parts with long-cycle operation requirements.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It maintains precise operation under complex wear and corrosive conditions, tailored for high-end electronic and industrial precision devices.
