Ultra-thin design with 7mm inner diameter for compact machinery and tight spaces. High-grade chrome steel construction ensures durability under continuous rotation. Available in ZZ (metal shield) or RS (rubber seal) variants for dustproof or waterproof needs.

Ideal for drones, medical devices, RC models, and micro motors. Smooth deep-groove raceway reduces friction by 30% compared to standard bearings. Heat-treated rings prevent deformation under high-speed operation (up to 18,000 RPM).
