Excellent load balance and moment load capacity<br />

Cylindrical rollers are arranged in a well-balanced<br />

form so that they can uniformly withstand loads in<br />

all directions. In addition, rows are arranged in<br />

such a way that the moment arm distance<br />

between the loading points is large under T0<br />

moment. A high moment load capacity can be<br />

obtained.<br />

When T0 moment is applied<br />

Excellent vibration characteristics<br />

As compared with ball types of the same size, these guides have higher rigidity and give smaller<br />

deformation under repeated fluctuating load. The natural frequency is high, and the vibration damping<br />

time is short.<br />

High running performance<br />

The optimum design based on the analysis of roller re-circulation behavior achieves smooth and quiet<br />

motion.<br />

Remark : Features mentioned above are those of <strong>Linear</strong> Roller <strong>Way</strong> Super X and <strong>Linear</strong> Roller <strong>Way</strong> X which are the typical roller guides.<br />
