1If the desired rail length is not available in the standard length (selectable), please specify the length in 1 mm increments (dimension configurable).
2If a 3- to 4-block product is desired, please select a part number for a 1-block product and specify "B3 (3 blocks)" or "B4 (4 blocks)" for alterations.
[ ! ]Heat resistant temperature is 0 to 50°C.
[ ! ]Features resin retainers between the steel balls to prevent the balls from coming into contact with each other, thereby helping minimize noise during high-speed operation.
[ ! ]For the type with resin retainers, blocks and rails can be purchased separately.
[ ! ]Blocks and rails cannot be purchased separately for MISUMI Linear Guides other than those with resin retainers.

3For L Dimension Configurable Types, both ends of the rail are evenly cut. G dim. resulting from this cutting process will differ from those indicated on the above table.
!Grease fittings are screw-in types, and thus, can be repositioned.
!Correctly match the datum planes (the side with the straight grooves) of both the rail and block.
Standard Rail Length (Selectable) List
The table below lists the standard rail lengths for each size. Please select the rail length from here.
Lengths not listed in the table below can be custom specified in 1 mm increments.

4The basic load rating is the same for all four directions (radial, reverse-radial, and lateral directions) relating to blocks. Can be used in any orientation.
- The guideline for the allowable load and allowable moment of the linear guide is the value obtained by dividing each value (above table) by the static safety factor fs (below table).
Example: Allowable load (kN) for H30 under normal driving conditions: 29.6/2 = 14.8 (Approx. 1,510 kg)
Static Safety Factor (Lower Limits of fs)
| Condition of Use | Lower Limits of fs |
|---|---|
| For normal operating condition | 1 to 2 |
| When smooth running performance is required | 2 to 4 |
| When there is vibration or impact | 3 to 5 |
Allowable Load (N) ≤ Co/fs
Allowable Moment (N⋅m) ≤ (MA, MB, MC)/fs
fs: Static Safety Factor Co: Basic Static Load Rating
MA, MB, MC: Allowable Static Moment (N⋅m)

■Datum Plane and Mounting Direction
- Datum plane has the Datum Plane Mark (groove) on the block and rail (Fig. A). Be sure to match the datum planes for use.
- The mounting direction shown in Fig. B is acceptable. All the basic load ratings are same.


■ Precautions for Use
[ ! ]Blocks are equipped with retainers to prevent the balls from derailing.[ ! ]For Interchangeable, Light Preload Type, rails and blocks can be interchanged.
[ ! ] Straight grooves are provided on datum planes. Be sure to match the datum planes for use. Be sure to match the datum planes for use.
[ ! ]Rails cannot be connected end to end.
[ ! ]The accuracy of Linear Guides is guaranteed after mounting the rail (after fastening screws on the rail and pushing it onto the datum plane).
Minor bending of the rail will be adjusted by being secured and will not affect the performance.
■Others
- Filled with lithium soap based grease (Alvania Grease S2 by Showa Shell Sekiyu K.K) before shipment.
Greasing with a different brand of grease is not recommended. Please use the same brand of grease. - Angled Grease Fitting Type
- Grease fittings are screw-in types, and thus, can be repositioned.
■Standard Grease Fitting Position
- When the datum plane is in front, the grease fitting is attached in the direction shown in the diagram below.



| ●Advantages of Lubrication Unit KL: Provides long term maintenance-free operation. Reduces maintenance cost. Most suitable where the design does not allow lubrication. |
