The 6708-ZZ is an ultra-thin section deep groove ball bearing engineered for applications where axial space is severely limited yet reliable rotary support is required. Featuring double metal shields (ZZ), this configuration provides effective protection against coarse debris while maintaining minimal frictional torque for high-speed operation. With a 40mm bore, 50mm outer diameter, and an exceptionally slim 6mm width, it is the preferred solution for optical instruments, medical imaging equipment, and lightweight conveyor rollers where compact packaging cannot compromise rotational precision.
