Linear Guides - For heavy load, with dust protection seals or metal scrapers.

Check FAQ of this product (1 item)

MISUMI

Linear guides of more robust sizes ideal for heavy loads, with the option of selecting them with standard block, or wide blocks. Configurable with seals for dust protection or with metal scrapers for solid bodies on the rail. Selectable lubricant type, even with MX constant lubrication accessory. Blocks and rails cannot be purchased separately.

[ ! ]Blocks and rails are not sold as separate items. Normal Clearance Type has guaranteed radial clearances and accuracies as sets of blocks and rails.
■Precautions for Use
[ ! ]Blocks are equipped with retainers (wire) to prevent balls from derailing. For blocks, see >> Click here
[ ! ]Radial clearances and accuracies are not guaranteed if the blocks and rails are interchanged from the original set combinations.
[ ! ]Straight grooves are provided on datum planes. Be sure to match the datum lines when using.
[ ! ]Rails cannot be connected end to end.
[ ! ]Running parallelism is the value measured after the rail is mounted. (it is not the value measured before the rails are fastened with screws.)
■Others
· Filled with Lithium soap based grease (Alvania Grease S2 by Showa Shell Sekiyu K.K).
· Grease Fittings: Straight Type for H24 and Angled Type for H28 and H33.
· Grease Fitting is screw-in type, and thus, can be repositioned.

Technical Information

Characteristics of Linear Guides

Linear guides utilize steel balls that roll on ground raceways, and the balls are recirculated using plastic return caps.
End seals prevent foreign materials from entering into the blocks.
Load ratings are the same for all four directions (radial, reverse-radial, and lateral directions). Can be used in any orientation.

Preload (Radial Clearance)

Type of guide	Preload	Height H Dimension	Radial Clearance (µm)
Linear guide medium/heavy load	Normal clearance	24	-4 ~ +2
		28	-5 ~ +2
		33	-6 ~ +3
	Light preload	24,28	-4 ~ 0
		30 ~ 42	-5 ~ 0
		42*	-7 ~ 0

* marked size is for Ultra Heavy / Extra Super Heavy Load

Clearance and preload of MISUMI Linear Guides are controlled with minute ball size adjustments.
Increased rigidity and reduced elastic deformation will result by preloading (negative clearance).
In general, selecting some preloads would have a positive effect on the accuracy and service life of the Linear Guides.
Blocks and rails manufactured by MIUSMI guarantee their own radial clearance (preload) and accuracy as sets of blocks and rails. Be sure to use the blocks and rails in sets.

Types of Greases

The following types of greases are used in MISUMI linear guides.

Grease	Linear Guide	Grease Model	Features
Standard	Miniature	Multemp Grease PS2 (Manufactured by Kyodo Yushi)	Grease with excellent low temperature and low torque properties.
	Miniature with MX lubrication unit	Tufflix MP2 (Manufactured by JX Nippon Oil & Energy)	Reduces temperature rise in the bearing area; extends bearing life and reduces grease replenishment interval and maintenance work.
	Medium Load Heavy Load	Albania Grease S2 (Manufactured by Showa Shell Sekiyu)	It has excellent lubrication and shows excellent performance under normal and heavy load conditions.
Type L	Miniature/Medium/Heavy Load	ET-100K (Manufactured by Kyodo Yushi)	It has excellent heat resistance, oxidation stability, adhesion and tackiness. It is also a low dispersion, low leakage grease.
Type G	Miniature/Medium/Heavy Load	LG2 (Manufactured by NSK Ltd.)	It produces little dust and has excellent wear resistance and rust resistance properties.

Maintenance

The grease forms an oil film on the steel balls and on the slideways of the linear guide, reducing friction.

Loss and deterioration of the grease will greatly affect the service life of the linear guide, so it must be lubricated on time depending on the conditions of use.

MISUMI linear guides are lubricated with standard grease at the time of shipment, so they can be used as is.

Recommended lubrication intervals

Lubricate every 6 months. If linear guide is used for long distances, it is recommended to lubricate every 3 months, or if it is used more than 1000 km in a period, we recommend every 1000 km.

*The above is the distance-based lubrication interval. If the grease deteriorates or is heavily contaminated due to the operating environment, it may be necessary to shorten the lubrication interval.

By using a lubrication unit, it is possible to extend the lubrication interval considerably.

MX Lubrication Units

Features

Long-term Maintenance-Free Condition

The special polyurethane in MX Lubrication Unit impregnates grease, and its micropore structure provides an optimal amount of grease on the raceway surface. A constant oil film is formed between steel balls and the raceway, enabling long-term maintenance-free operation.

Cost Benefit

Extended lubrication intervals result in reduce maintenance cost.

Short Lead Time

Ship time is the same as that of standard products.

Structure

Special polyurethane (yellow color) has interconnected micropores and has excellent water-holding capacity. This allows the unit to hold more grease.

Test Results

The linear guides with MX lubrication unit achieved 2,000 km of travel, more than the standard units without grease

Test conditions

Sample	SXR24

Double-Sealed

- Double gasket design with two layers of side gaskets increases the sealing efficiency and prevents ingress of foreign materials into the block.

- Can be used where dust and machining chips exist.

[!]Sliding resistance of Double-Sealed Type is higher than that of Standard Type.

With Metal Scrapers

- Larger debris adhering to the rail can be removed by attaching metal scrapers to the outside of the side seals.

- Can be used in areas with high temperature dusts such as welding spatter.

Cautions

If the linear guides are handled incorrectly, the quality may deteriorate. When using MISUMI linear guides, consider the following points:

Be careful when removing the blocks

MISUMI linear guidesare equipped with a retainer, so that the balls will not fall out even if the block is removed from the rail. However, if the block is removed from the rail at high speed or inserted at an angle, the balls may fall out. Be careful when removing and installing the blocks.

Blocks and rails not sold separately

Linear guides MISUMI are only sold as a block and rail assembly. For resin retainer type only, blocks and rails can be purchased separately.

Please do not replace with another product

The radial clearance and accuracy of MISUMI linear guides are guaranteed as a block and rail assembly, so the accuracy is not guaranteed when combined with another product.

Please check the reference surface before installation.

Linear guides have reference planes on both the rail and the block (the side with a straight groove is provided). When installing the linear guide, correctly align this reference surface with the mounting reference surface of the table and base and secure it. For more details, refer to"Installation" in "Support Information".

Please do not add rails

MISUMI linear guides are shipped with chamfered edges on the end of the rail. The use of additional rails is not covered under warranty.

Secure all rail mounting holes.

The rail curvature is corrected with all mounting holes clamped. Accuracy is guaranteed under these conditions.
