THK is now accepting orders for the Super-Low Waving Caged Ball LM Guide (Model SPH).

 The Super-Low Waving Caged Ball LM Guide is an LM Guide with ISO-compliant dimensions that demonstrates super-low waving. It has achieved super-low waving* that is best-in-class among linear motion guides by adopting an eight-row structure and small-diameter balls. This contributes to improved measurement accuracy, positioning accuracy, and machined surface quality, making it possible to address fields that require nanometer-level motion precision.

 The conventional Super-Low Waving LM Guide Model SPR/SPS was limited in application to guide sections of some equipment due to the use of proprietary THK dimensions, but the Super-Low Waving Caged Ball LM Guide has dimensions that conform to ISO standards (globally standard dimensions) and can replace existing products.
 In addition, the four-way equal load enables use in any orientation, making this product even more suitable for customers in the high-precision market—not only in semiconductor and LCD equipment-related applications, but also in machine tools.

 THK will continue to use the technology and know-how it has cultivated as a top manufacturer of machine components to contribute to the performance of a wide range of equipment.

 * Waving is a phenomenon in which the relative positions of the LM block and balls change due to the rolling of the interior balls (rolling elements) as the LM block moves on the LM rail, which affects straightness. Particularly in high-precision machinery, waving must be reduced as much as possible.
