High positioning accuracy, high rigidity, high speed, and easy maintenance.
High Positioning Accuracy
Linear guides have very low friction resistance during motion, allowing the table to be driven with minimal power compared to sliding friction. Due to the low friction resistance, the frictional heat generated during motion is also reduced. Compared to conventional sliding friction, the wear on the rolling contact surfaces of the rails is significantly decreased, maintaining high positioning accuracy and low wear even during prolonged operation.
High Rigidity
The block and rail have a circular arc groove shape, allowing them to bear loads from all directions. With a DF structure, they exhibit excellent error absorption capabilities. By applying pre-load, it is possible to achieve high rigidity.
Easy Maintenance
In the case of sliding guides, it is necessary to constantly form an oil film on the sliding surfaces and to force a large amount of lubricating oil, which requires significant time and cost for maintenance. Linear slides only require regular lubrication, making maintenance easy while also maintaining the machine's operational accuracy.
High Speed
The block, rail, and balls have a rolling contact structure, resulting in a low coefficient of friction and minimal frictional heat generation. Machines can operate with small power, leading to significant energy savings, making them more suitable for high-speed motion compared to sliding guides.
