Can linear guides or sliders be purchased separately?

Taking into account the accuracy of products, single slider models clearly indicated in the catalog can be purchased, and no others can be purchased.

Can the stainless steel guide rails be guaranteed not to rust?

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.

What problems should be paid attention to when the linear guide is installed vertically?

Attention should be paid to prevent the slider from falling off and causing the balls to fall off during installation.

What does micro preloading in linear guide mean?

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.

Linear guide indicators include basic dynamic load rating and basic static load rating. Which indicator is the reference when selecting?

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.

Can the corresponding linear guide products be selected according to the third-party guide rail model?

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.

Can the rail or slider be repaired if it is damaged?

Repair service is not provided, re-purchase is recommended.

Can linear guide length be arbitrarily specified?

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.

Product Overview

Linear guide rails, also known as slide rails, linear guides, or linear slide rails, are used for linear reciprocating motion applications. They have a higher rated load than linear bearings while maintaining the same volume of moving components, as well as linear motion accuracy. They can also bear a certain amount of torque load, enabling high-precision linear movement under high load conditions.
Linear guide rails are used to support and guide moving parts, allowing them to move in a reciprocating linear motion along a specified direction. They are mainly used in mechanical structures that require high precision. The moving and fixed components of the linear guide rail do not use an intermediate medium, but instead employ rolling steel balls.

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 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.

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
Whether the mounting surface produces interference

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

③ Whether the error values of guide parallelism and fitting height are within the allowable installation values
MISUMI parallelism error tolerance

④ Use the standard installation method

Maintenance (supply of grease)
Grease forms an oil film on the surface of the linear guide ball and rolling 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.
Miniature: Lithium Soap based Grease
Recommended grease filling interval: Usually every 3 months
Depending on the operating environment, the grease injection interval must be shortened appropriately when the grease is aging and dirty.

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 Economy series Miniature linear guide rail adopts bearing steel. If you have anti-rust requirements, please choose the Low Temp. Black Chrome Plating Surface Treatment or Stainless Steel SUS440C products.

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.
