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 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.

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

Frequently asked question (FAQ)

Question: Can linear guides or sliders be purchased separately?
Answer: Taking into account the accuracy of products, single slider models clearly indicated in the catalog can be purchased, and no others can be purchased.
Question: Can the stainless steel guide rails be guaranteed not to rust?
Answer: Stainless steel is a product that has a certain antirust function compared to carbon steel, but it cannot be guaranteed that it will never rust. Depending on the operating environment, there may also be short-term rust.
Question: What problems should be paid attention to when the linear guide is installed vertically?
Answer: Attention should be paid to prevent the slider from falling off and causing the balls to fall off during installation.
Question: What does micro preloading in linear guide mean?
Answer: MISUMI's linear guides control the clearance by selecting the size of the internal ball. Through the negative clearance, the rigidity is improved and the elastic displacement is reduced. This is preloading. Generally speaking, the life and accuracy of the micro preloading type will be better than that of the standard clearance type.
Question: Linear guide indicators include basic dynamic load rating and basic static load rating. Which indicator is the reference when selecting?
Answer: The basic dynamic load rating is used to calculate the rail life, and the basic static load rating is used to calculate the maximum allowable load.
Question: Can the corresponding linear guide products be selected according to the third-party guide rail model?
Answer: MISUMI offers third-party brand replacement services, so as long as the third party product model is given, we can replace it with corresponding MISUMI model. For details, please contact the customer service email or call the customer service phone.
Question: Can the rail or slider be repaired if it is damaged?
Answer: Repair service is not provided, re-purchase is recommended.
Question: Can linear guide length be arbitrarily specified?
Answer: It can be specified arbitrarily. However, MISUMI linear guides are divided into length fixed type and length specified type, and in case of length specified type, the length dimensions for length fixed type cannot be specified.
