6700 Series Ultra Thin Section Deep Groove Ball Bearings

6700 series deep groove ball bearings are ultra thin-section miniature bearings designed for compact and limited installation space. Different from standard thick bearings, the 6700 series features extremely thin wall, lightweight structure and low load design. It is widely used in precision instruments, miniature motors, medical devices, optical equipment and small automated machinery. All 6700 bearings are made of high-purity GCr15 bearing steel to ensure stable rotation, low noise and long service life. We supply full range seal and clearance variants and support factory wholesale and mixed batch orders.

Product Features

Ultra Thin Wall Structure: Special thin cross-section design saves more installation space for compact precision equipment.
Light Load & Low Friction: Optimized internal structure ensures smooth, quiet and stable high-speed operation.
Multiple Protection Options: Open, ZZ dust-proof and 2RS waterproof sealed types for different working environments.
High Precision Performance: Fine grinding raceway reduces vibration, suitable for precision instrument operation.
Customizable Structure: Standard steel cage, nylon cage and C3 enlarged clearance are available on request.
Factory Stable Supply: Complete 6700 series models, support small mixed orders and bulk wholesale.

Application Range

6700 thin section bearings are widely applied in precision instruments, optical equipment, miniature motors, medical devices, office equipment, smart home appliances and small automated machinery. This series belongs to light-load precision bearings, not applicable for heavy-duty impact working conditions.
