16	7.2	14.3	86.0	86.0	305.2	228.3	228.3	610.4	0.3	2.95

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.

5The allowable static moment when two blocks are in close contact is not a guaranteed value but a reference value.

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 H12 under normal driving conditions: 5.3/2 = 2.65 (Approx. 271 kg)
The actual friction resistance (required thrust) when using a linear guide will vary depending on the load and other factors.

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) ≤ (M_A, M_B, M_C)/fs

fs: Static Safety Factor Co: Basic Static Load Rating
M_A, M_B, M_C: Allowable Static Moment (N⋅m)

Friction Resistance (Required Thrust Force)

・In linear guides, the rolling elements perform rolling motion, resulting in lower frictional resistance compared to sliding guides.
However, this can vary depending on the applied load, speed, and the characteristics of the lubricant.
Especially when a moment load is applied or preload is applied, friction resistance increases. Although seal resistance varies depending on the seal lip press-fit allowance
and the condition of the lubricant, it is not proportional to load and always shows a constant value. Friction resistance is obtained by the following formula.

F＝μ・w＋f

F: Friction Resistance (N)
μ: Dynamic Friction Coefficient
w: Load (N)
f: Sliding Resistance (Seal Resistance)

Dynamic Friction Coefficient

Type	Dynamic Friction Coefficient (μ)
Miniature Linear Guide	0.004 to 0.006
Linear Guides for Medium Load	0.002 to 0.003

Calculation Example

Condition: Miniature linear guide (standard rail) assembly height (H): 10: Sliding resistance (seal resistance): 0.5 (N)
Dynamic Friction Coefficient (μ): 0.005
Load: 150 (N)

F (Friction Resistance)＝0.005×150+0.5＝1.25(N)

Mounting and Handling
■ 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.

Fig. Ａ

Fig. Ｂ

■ Precautions for Use
[ ! ] Blocks are equipped with a retainer to prevent balls from derailing (wires).
[ ! ] 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 planes for use.
[ ! ] Rails cannot be connected end to end.
[ ! ] The accuracy of Linear Guide is guaranteed after mounting the rail (after it is fastened with 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.

■ About Grease

Filled with a standard grease: lithium soap based grease (Multemp Grease PS2 by KYODO YUSHI) before shipment.
Greasing with a different brand of grease is not recommended. Please use the same brand of grease.
Apply grease directly to the rail. After applying, move the block to let the grease absorb.

■ Standard Grease Fitting Position

The miniature type does not come with a grease fitting or greasing hole.
