FRICTIONAL RESISTANCE

IV. ARRANGEMENT

As the static and dynamic coefficient of frictions of the SBC linear guide are so small that they minimize the requied driving force and temperature increase. Frictional force depends on load, preload, velocity and lubrication. In general, the light load with high speed is more affected by the lubricant characteristic, while the medium or heavy load are more affected by the load.

SBC linear rail can be arranged in various configurations. As shown below, (1), (2), (3) and (4)are the most common methods. (5), (6), (7) and (8) are very effective methods when the height of the table is limited.

If a seal is applied, seal resistance has to be added up to the total required driving force. The seal resistance to motion is a factor of its contact area, pressure and lubrication. When heavy load or pre-load is given to the block, the resistance to motion of the linear guide increases, ■ If there are a pair of seals , 0.2~3.5(Kgf) must be added according to each model number.
