The Bosch Rexroth LINEAR-SET LSATE-A-12-DD (R103261220) is a high-quality linear motion system designed for precise and smooth movement in various applications. This system features a lightweight precision tandem housing made from aluminum, which houses two super linear bushings A with self-alignment capabilities, ensuring optimal performance and reliability. The set includes an external reference edge and seals for protection against contaminants, making it suitable for environments where cleanliness is paramount. The linear set is equipped with a shaft diameter d and offers standard relubrication options to extend its service life. It is characterized by its ability to handle dynamic load capacities efficiently when both linear bushings are under equal load, with specific factors provided for non-main direction loadings to ensure accurate capacity calculations. The maximum acceleration (amax) and permissible ambient temperature range demonstrate the robustness of the unit under various operational conditions. With a breakaway force specified for size H, the LINEAR-SET LSATE-A-12-DD ensures low frictional start-up forces, while the maximum permissible linear speed (vmax) indicates its capability to operate at high speeds without significant wear on plastic components. Service life tests have shown impressive travel distances without failure, highlighting the durability of this system. Additionally, this linear set comes clamped to h shaft lower limit and set to zero-clearance, offering immediate precision upon installation. For applications requiring preloaded guides, an adjusting screw allows easy adjustment of radial clearance. The product's weight reflects its lightweight design without compromising strength or performance. This Bosch Rexroth linear set also comes with the option of being configured as a Linear Motion Slide, providing versatility for different application needs. Its dynamic longitudinal moment load capacity and static longitudinal moment load capacity further contribute to its overall robustness and suitability for complex loading scenarios in linear motion tasks.

Impact of load direction on load rating of closed Linear Bushings
The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.
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.
