■ Detailed dimension of L 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 rail at this time.
In addition, Dimension E's calculation formula is as follows

2-Block Specifications	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 Specifications	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 Specifications	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.

Low temperature black chrome plating (rail)	R	The rail undergoes low temperature black chrome plating surface treatment
Rail End Cut	Left End Cut ES	Specify the edge distance in 0.5 mm increments. When the specified edge distance exceeds or is close to the hole spacing, cutting may result in hole breakage. EB + ES = 2E. In cases where cutting is not feasible, distribute the dimensions evenly according to the standards.

*The precision of the Economy series products has been improved.

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.

■ 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.




■ About maintenance (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 listed below at the time of shipment, so they can be used directly.
Miniature Linear Guide: Lithium Soap-based Grease (MULTEMP Grease PS2)
Medium· and Heavy Duty Linear Guide: Lithium Soap-based Grease (Showa Shell Petroleum Albania Grease S2)
② Recommended Grease Injection Interval:
  Usually every 6 months.
For longer moving distance, 3 months, or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail.
  *The above is the grease injection 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.
