Miniature Linear Guides Wide Rails

Linear guides (also known as slide rails or linear slides) are designed for precise linear motion and are used in high-precision applications. They provide higher load capacity and motion accuracy than linear bearings of the same size. These guides use rolling elements (such as steel balls) instead of an intermediate medium, allowing for smooth, precise movement even under high load conditions. They are commonly used in equipment like CNC machines, robotics, and automated systems.

The dimensional tolerance of L length is ±1mm and
The dimensional tolerance of E end distance is ±0.5mm

■ L Detailed dimension of dimension specified type
Dimension L specified type cuts both ends of the rail equally. Refer to the table below for the number of mounting holes (M) of the slide rail at this time.
In addition, E dimension is calculated with the formula below.
  
L : Guide Rail length
M: Guide Rail mounting holes
P: Guide Rail holes pitch

Rail End Cut	Left End Cut ES	Specify the edge distance in 0.5 mm increments. When the specified edge distance exceeds or is close to the hole spacing, cutting may result in hole breakage. EB + ES = 2E. In cases where cutting is not feasible, distribute the dimensions evenly according to the standards.

[Running Parallelism]
The values in the table are measured after the slide rail is fixed on the base.
When moving the slider within the entire length of the slide rail, measure the change of the upper surface C of the slider relative to the bottom surface A of the slide rail, and the change of the reference surface D of the slider relative to the reference surface B of the slide rail.
When moving the sliding block within the entire length of the slide rail, measure the change of the upper surface C of the slider relative to the bottom surface A of the slide rail, and the change of the reference surface D of the slider relative to the reference surface B of the slide rail.
