Features
Suited for Single Rail Applications
High Rigidity in the Rolling Direction
The Model HDR features a rigid design that can be used even in tables configured for one LM Guide. It enables single-axis tables to be compact and lightweight.
Ideal Applications
Other Single-Axis Configurations Where the Model HDR Excels
LM Rail Surface Protected from Foreign Materials
The ball raceways of the Model HDR are featured on the sides of the LM rail, making it difficult for foreign materials to reach them.
Applications where foreign materials might stick to the LM rail surface include
- Woodworking machine that may produce wood chips
- Tire manufacturing machines where rubber may get on the rail
- Resin molding machines where resin may get on the rail
To use the product more safely, plate covers can also be installed to improve the contamination protection performance.
Structure of the HDR
The Model HDR features raceways on the sides of the LM rail, which come into contact with the balls at a 45° angle. This design is resistant to tilt in the rolling direction.
DB Structure (Back-to-Back)
This contact structure is designed so that the raceways fully support the balls even when an MC moment is applied. As a result, this design is highly rigid and resistant to tilt in the rolling direction. It is often used in conjunction with angular ball bearings when the moment load is high.
4-Way Equal Load
The Model HDR is designed to equally bear loads applied to the LM block from four directions. (Four directions: radial, reverse-radial, horizontal) As a result, this model can be used in any orientation, enabling a wide variety of applications.
Globally Standard Dimensions
The Model HDR's dimensions conform to world-standard ISO specifications (ISO 12090-1:2011 Rolling Bearings). The Model HDR's dimensions conform to world-standard ISO specifications (ISO 12090-1:2011 Rolling Bearings).* US/UT and UV/UW types differ from ISO dimensions.

| The flange of this LM block has tapped holes. This type can be mounted from the top or the bottom. It is used in places where the table cannot have through holes for mounting bolts. | With this type, the LM block has a smaller width (W) and tapped holes. It is ideal for compact designs. | This type has a shorter height (M) than the R/LR and a more compact design. |
LM Blocks and LM Rails Available Separately
The Model HDR features a lineup of interchangeable LM blocks and LM rails that can be combined freely as long as they have the same model number.
