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.

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.

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.

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

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

Can the corresponding MISUMI 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 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.

(!) Since support from Microsoft will end on January 14 2020, Windows 7 user might not be able to use MISUMI website effectively. Please consider to update your system as ‘MISUMI Website system requirement’.

Product Description

Linear Guides Standard Block-Low Profile
These linear guides or linear slides are an economy item, The price is cheaper than the MISUMI standard product.They offer a wide variety of sizes to choose from.
[Feature]
● Rail Length Minimum/Maximum (mm.): 160 and 520
● Assembly Height (mm.): 24, 28, 33, and 42
● Option: Set (Rail + Block) / Block only
● Material: Carbon Steel
[Application]
It is used in a variety of machines such as CNC machines, 3D printers, measuring instruments, and so on.

Product Overview

Linear Guides, also known as slide rail or linear slide, which is used for linear reciprocating motion, has higher rated load and linear motion precision than linear bearings under the same moving component volume. Also, it bears a certain torque load, achieving high-precision linear motion under high load.
Used to support and guide moving parts, Linear Guides make reciprocating linear motion in a specified direction. It is mainly used in mechanical structures with high precision requirements. Rolling steel balls are used instead of intermediate medium between the moving element and the fixed element of the linear guide rail.

Product Features

Feature of Linear Guides 1: Standard rails are equipped with dust covers to prevent dirt from accumulating in the mounting holes when the equipment is in use.
Feature of Linear Guides 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 of Linear Guides 3: Due to a point-to-surface contact, the frictional resistance is small, and it can perform subtle movements to achieve device positioning.
Feature of Linear Guides 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 of Linear Guides 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.

Selection Calculation

The service life of linear guide is divided into 3 categories as follows:
① Operating distance life

When the linear guide makes the linear reciprocating motion under load, the repeated stress is often applied to the rolling element (steel ball) or rolling surface (slide rail), resulting in scale-like damage, which is called fatigue stripping of material. The total moving distance before the initial stripping is called the service life of linear guide.

② Rated life

The rated life refers to the total travel distance reached by a group of linear guides moving under the same conditions, with 90% not stripping. The rated life can be calculated with the following formula based on the basic dynamic rated load and the load applied on the linear guide.

The load shall be calculated before using a linear guide. It is not easy to calculate the load during the linear reciprocating motion, because there may be vibration or impact during the motion, requiring a full consideration to the distribution of vibration or impact relative to the linear guide. Operating temperature and other factors also have great influence on the service life. Taking all these conditions into account, the above calculation formula is changed into the following one.
Rated life

③ Operating time life

The service life can be calculated by obtaining the travel distance per unit time. When the length of the stroke and the number of strokes are determined, it can be calculated according to the following formula.

Usage Method

■ About use of Linear Guides
① MISUMI's Linear Guides 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 Low Temp. Black Chrome Plating Surface Treatment or Stainless Steel SUS440C products.

MISUMI Economy series Linear Guide Slider Precautions

■ About maintenance of Linear Guides (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 at the time of shipment, so they can be used directly.
② Recommend grease filling interval:

Usually, perform the grease filling maintenance once every 3 months.
The specific maintenance time shall be adjusted according to the actual situation. It is recommended to check the grease condition once every 100 km.
* The above is the grease filling 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 of Linear Guides, the installation of the linear guide needs to meet the following four points:

① Whether the shape of the mounting surface produces of Linear Guides interference
Required shape of linear guide mounting surface

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

Allowable height error tolerance of linear-guides

④ Use the standard of Linear Guides
