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
here.
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 lifeThe 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.
③ Operating time life
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.
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.

■ 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.
■ 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:

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
② Keep the flatness of the workpiece mounting surface at about 5μ, otherwise the slider will be slightly deformed
③ Whether the error values of guide parallelism and fitting height are within the allowable installation values
④ Use the standard of Linear Guides
