See the notes on installing Linear Sets with side opening.
For load in the direction of opening, please refer to the loading diagrams (see "Diagrams" section).
Impact of load direction on load rating of open Linear Bushings
The load ratings C and C0 apply for the main direction of loading ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fρ (dynamic load rating C) or fρ0 (static load rating C0).
Installing specific Linear Bushings can prevent reductions in load capacity (see Linear Set with side opening).
Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the super Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
| 1) | fs = factor |
| 2) | s = movement path |
Reduced load capacity with high load
If the load F on a Super Linear Bushing A is more than F > 0.5 x C, the dynamic load rating C decreases.
Definition of dynamic load ratings
Self-alignment feature
The self-alignment feature in the steel bearing plates and machined ball guide grooves ensure quieter travel. The flow chart shows a comparison with a conventional Linear Bushing. The example is based on a load of 800 N and misalignment of about 8 ft (caused by shaft deflection).
Due to the self-alignment feature, two super Linear Bushings must be used on at least one of the shafts in the guide.

Radial clearance
The radial clearance values shown in the table have been determined from statistics and correspond to values expected in practice. The adjustable Linear Sets come clamped to an h5 shaft (lower limit) and set to zero clearance.
Vertical dimension
The tolerance values for the vertical dimension "H" for the Linear Sets shown in the table have been determined from statistics and correspond to values expected in practice.
Bolts
We recommend bolts in accordance with ISO 4762-8.8 for fastening the Linear Sets.
Lubrication
On-shaft relubrication on relubricatable Linear Bushing only until lubricant seeps out.
Notes on installing Linear Sets with side opening
No reference edges:
Straighten the first shaft using the shaft support rail and fasten it in place. Align the second shaft parallel to the first and fasten it in place. Slide the Linear Sets onto the shaft and fasten them to the machine table.
With reference edges:
Press the first shaft with shaft support rail onto the reference edge and fasten the shaft support rail in place. Align the second shaft parallel to the first and fasten the shaft support rail in place. Slide the Linear Sets onto the shafts. Next: with one reference edge on the machine base and one on the machine table: Press the Linear Sets on the first shaft onto the reference edge of the machine table and fasten into place. Fasten the Linear Sets on the second shaft to the machine table. with just one reference edge on the machine base: Fasten Linear Sets to the machine table.
