Basic rating load / Application examples
Basic rating load
6 roller followers
The rating load can be changed, owing to the positions of the load and the roller followers.
- A direction: perpendicular to the flat part of the post (roller follower)
- B direction: perpendicular to the center of the post (between the roller followers)
Life time calculation
Life time calculation is followed by the radial load calculation to the shaft guide housing. However, a guideline is the shorter one of the calculations "1.basic rating life" or "2.oscillation life". In case the stroke is too short, the guideline is "2.oscillation life".
Relationship between the oscillation
coefficient and half of oscillation
angle (outline)
1.Basic rating life
Basic rating life means the total rotation number 90% of a group can rotate under the same condition without any flaking by the rotation wearout.
2.Oscillation life calculation

Actual examples of shaft guide
Elevation stage with single axis
Applicable for the large shaft Z axis elevation stage or the Z axis feeding device by the reasons that 1) up to φ150 shaft can be handled and 2) the hexagonal post structure contributes to the rotation stop.
- Over φ100 is upon request.
Large die set
Suitable for the guide post of large die set or 3-plate die set by its long stroke with retainer-less structure.
- Please contact us for the long stroke specifications due to our manufacturing equipment limit.
Servo-press unit
Construction of the shaft guide (hollow shaft type) with precision ball screw. We also merchandize high-rigidity and no-backlash servo press. Please refer to "Precision servo press catalog".
