Linear Guides Long Blocks

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 Guides rail.

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.)
Since this product has no surface treatment, please be sure to take anti-rust measures.
Dimension E of length specified type needs to be calculated. Please refer to "detailed dimension of Dimension L specified type" for calculation method

■ L Detailed dimension of dimension specified type
Dimension L specified type cuts both ends of the rail equally. Refer to the table below for the number of mounting holes (M) of the slide rail at this time.
In addition, E dimension is calculated with the formula below

Alterations

2 Block Specification	B2	1 block added to 1-block product to ship as 2 block item. If the rail is too short to fit multiple blocks, the blocks will be shipped in a separate package.
3 Block Specification	B3	2 blocks added to 1-block product to ship as 3 block item. If the rail is too short to fit multiple blocks, the blocks will be shipped in a separate package.
4 Block Specification	B4	3 blocks added to 1-block product to ship as 4 block item. If the rail is too short to fit multiple blocks, the blocks will be shipped in a separate package.
Preload adjustment	ZA Light Preload	Change “No Preload Prodcut” -> “Light Preload Product” or “Medium Preload Product”
	ZB Medium Preload
Rail Ends Cut	ES Left End Cut	ES & EB will be the distance from the edge to the center of the left-hand hole and the right-hand hole respectively.  Only either ES or EB can be selected. When ES or EB is indicated, the distance from the edge to the center of the opposite side will be changed but the total rail length will remain unchanged.

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

The service life of linear guide is divided into 3 categories as follows:
① Operating distance life② Rated life③ Operating time life

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.


■ About maintenance of Linear Guides (supply of grease)
① Grease forms an oil film on the surface of the Linear Guides 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:

Precautions

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