The 6702 is a high-precision open-type thin-section bearing designed for advanced mechanical systems that prioritize ultra-low starting torque and unrestricted lubrication access. By omitting integrated seals or shields, this model achieves the lowest possible rotational friction, making it an ideal candidate for high-speed oil-bath environments and sensitive measuring instruments. With a 15mm bore and a slim 4mm profile, the 6702 serves as a critical rotational support for hollow-shaft encoders, robotic joints, and aerospace-grade telemetry systems.
