Features of the LM Guide
Large permissible load and high rigidity
Accuracy averaging effect by absorbing mounting surface error
Ideal four raceway, circular-arc groove, two point contact structure
Superb error-absorbing capability with the DF design
Low friction coefficient
Wide array of options (QZ lubricator, Laminated contact scraper LaCS, etc.)
As a result, the following features are achieved:
Easy maintenance
Improved productivity of the machine
Substantial energy savings
Low total cost
Higher accuracy of the machine
Higher efficiency in machine design
Linear Guide Characteristics
Light movement with no clearance
As linear guides are rolling guides, they have no clearance and lighter movements than sliding guides.
Infinite linear motion is possible
Rolling guides such as cross-roller guides and ball guides have finite strokes, but the linear guide's balls recirculate endlessly, which means that the stroke can extend to however long the rail is made.
High permissible load
The linear guide's raceways are curved grooves, which provide surface contact between the balls and raceways. This makes the permissible load about 13 times greater than that of guide components with point contact, such as linear bushing. As a result, a linear guide can achieve a similar permissible load as a point-contact type through a more compact design.
Power-Flo Technologies is proud to partner with THK as they contribute to the improvement of infrastructure and more efficient expansion of industry.
