Product Overview

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.

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

Product Features

Feature 1: New construction, greatly reducing noise and improving smoothness.
Feature 2: The slide rail and the slider are in contact with each other through the rolling ball, so the shaking is small, and it is suitable for equipment with precision requirements.
Feature 3: Due to a point-to-surface contact, the frictional resistance is small, and it can perform subtle movements to achieve high precision positioning of the control device.
Feature 4: It has a large allowable load because the force on the rotating surface is dispersed due to the rolling groove of the ball.
Feature 5: It is suitable for high speed motion because it is not easy to produce friction heat when operating and not easily deformed by heat.

Usage Method

■ About use
① MISUMI's linear guide is installed with a retainer. Although the ball is not easy to fall off when the slide block is removed, the ball may fall off if the slider is removed from the rail at high speed, or tilted into the slide rail. Please disassemble the slider with care.
② Be sure to avoid colliding the ball back groove cover, otherwise it will affect the ball cycling, resulting in poor sliding.
③ If you have anti-rust requirements, please choose the Vacuum Chrome Plating Surface Treatment or Stainless Steel SUS440C products.
MISUMI Miniature Linear Guide Slider Precautions

■ About maintenance (supply of grease)
① Grease forms an oil film on the surface of the linear guide ball and rail surface to effectively reduce friction and prevent sintering.
Decrease and aging of grease will greatly affect the life of the linear guide, so please add grease at the right time according to the service conditions.
MISUMI's linear guides are sealed with the greases listed below at the time of shipment, so they can be used directly.
② Recommend grease filling interval:
Usually every 6 months.
For longer moving distance, 3 months, or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail.
*The above is the grease injection interval under the moving distance standard. Depending on the operating environment, the grease injection interval must be shortened appropriately when the grease is aging and dirty.

Precautions

For normal use, the installation of the linear guide needs to meet the following four points:

① Whether the shape of the mounting surface produces interference
Flatness of MISUMI mounting surface

② Keep the flatness of the workpiece mounting surface at about 5μ, otherwise the slider will be slightly deformed
MISUMI parallelism error tolerance

③ Whether the error values of guide parallelism and fitting height are within the allowable installation values
Allowable height error tolerance of linear-guides
