1) driven axle to zero clearance small. After DuoCi process improvement, from QL series of fully to round has already achieved little axial zero clearance follower. Adapt to all kinds of precise positioning occasion.
2) double row subdivision design. 28 subdivision circumference for all to round when running smoothly, avoid to round up all the usually run jitter severe faults.
3) the wheels, small embedded bearing design. The whole round 28 a small rubber wheel were embedded 56 miniature bearing. The axis of sliding friction into the rolling friction is, make the lateral movement flexible smooth, truly realize all the lateral movement to round the resistance performance.
4) small wheels adopt selected high quality rubber, drum shape design, soft hard right grip, strong, run nearly mute. The measured in wood, ceramic tile, carpet on the surface of a good grip.
5) products for high temperature surface paint processing, beautiful and durable.
