The Bosch Rexroth LINEAR-SET LSATO-A-25-DD (R108762520) is a high-precision linear motion system designed for applications requiring smooth and accurate guidance. This linear set is constructed from lightweight aluminum and features a tandem, open design with two super linear bushings A, ensuring a high level of rigidity and load capacity. The inclusion of external seals provides additional protection to the internal components, enhancing the durability of the system. With a shaft diameter of 'd,' this linear set comes equipped with the capability for relubrication, allowing for maintenance and extended service life. The Series Super A bushings include a self-alignment feature that facilitates easier installation and can compensate for misalignment, resulting in smoother operation. The product has been engineered to handle dynamic load capacities effectively while maintaining a low friction force FR, which is critical for applications where efficiency and minimal resistance are essential. The LINEAR-SET LSATO-A-25-DD can operate within a wide range of ambient temperatures and is capable of handling maximum accelerations as well as breakaway forces without compromising performance. It offers impressive static and dynamic load ratings, making it suitable for long guides that require shaft support. Its ability to achieve high speeds up to 'vmax' meters per second showcases its versatility in various operational conditions, although it is noted that service life may be limited by increased wear on plastic parts under such circumstances. Weighing in at only 'weight,' this Bosch Rexroth linear set remains easy to handle while providing robust support for guided motion. Overall, this product represents an optimal solution for those seeking reliable linear motion technology combined with ease of maintenance and longevity.

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.
