In the case of Longer lengths, please contact us.

The kit includes 1 block. For additional blocks, please purchase a single block model.

The reference surface is set on the side of the block and slide rail with the linear groove. When used, make sure to align the two reference surfaces with each other.

The running parallelism is the value after the slide rail is fixed. (It is not the value before the screws of the slide rail are tightened.)

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.

Example of Use

Mechanism name: Belt-driven handling device
Feature of Linear Guides 1: Suitable for medium precision and medium frequency driving and positioning.
Feature of Linear Guides 2: A linear guide is configured in the center to achieve miniaturization.

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, the installation of the Linear Guides needs to meet the following four points:

① Linear Guides Whether the shape of the mounting surface produces 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
