- Designed to ISO standards, provides the compatibility with existing linear guides offering flexibility across applications.
- Features with our eight-row design to minimize waviness to ensure precision at the nanometer range.
- Choose from standard sizes 25-45 with the options for standard or extra-length guide carriages to accommodate diverse load capacities.
With the new SPH series THK offers a newly developed eight-row linear guide with Caged Ball that offers ultra-low waving during linear movements with standard dimensions compliant with the ISO standard.
Caged Ball LM Guide
ISO-Compliant Dimensions Super-Low Waving Model SPH
By adopting eight rows of raceways and small-diameter balls, the number of load-bearing balls within the LM block has been increased. This in turn enables the highest level of waving performance among THK LM Guide products, with super-low waving on a nanometer-level scale.

ISO-Compliant Dimensions
Dimensions conform to globally standard ISO specifications (ISO 12090-1:2011 Rolling Bearings) even with an eight-row structure. This product comes in four sizes ranging from 25 to 45, and a lineup of six block types is available: C/LC, V/LV, and R/LR.
Available Versions
SPH-C/LC
The flange of the LM block has tapped holes. It can be mounted from the top or the bottom. It is used in places where the table cannot have through holes for mounting bolts.
SPH-V/LV
The LM block has a smaller width (W) and tapped holes. It is used in places where the space for table width is limited.
SPH-R/LR
The LM block has a smaller width (W) and tapped holes. It is used in places where the space for table width is limited. It maintains the same height dimension as the Full-Ball LM Guide Model HSR-R.
