The Bosch Rexroth LINEAR-SET LSA-A-40-DD (R103564020) is a high-quality linear motion system designed for precise and smooth linear movement in various applications. This linear set comprises an aluminum housing with an integrated super linear bushing A, which is renowned for its self-aligning feature, providing reliable guidance and reducing installation time. The robust construction includes two external seals that protect internal components from contaminants and extend the system's service life. The product is characterized by its lightweight precision housing made of aluminum, contributing to the overall efficiency of machinery by reducing inertia. It is equipped with a standard shaft diameter 'd' that ensures compatibility with a range of setups. The R103564020 model is capable of withstanding dynamic loads, as indicated by its dynamic load capacity 'C', which should be adjusted based on the direction of loading using specific factors provided for different shaft diameters. With a maximum acceleration 'amax' and a permissible ambient temperature range from -20°C to +80°C, this linear set can perform reliably in diverse environmental conditions. It has been engineered to maintain performance up to a maximum permissible linear speed 'vmax', although higher speeds can result in increased wear on plastic components. The static load rating 'C' further highlights the system's ability to handle loads without deformation or damage when stationary. This model boasts an impressive service life, having undergone tests that demonstrate longevity over significant travel distances without failure. Additionally, the LINEAR-SET LSA-A-40-DD features friction force characteristics that are essential for understanding the resistance encountered during operation when not under radial load. Weighing only 0.7 kg, it provides an optimal balance between strength and weight, making it suitable for precision guides where easy installation and fixed working bore diameter are crucial requirements.

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.
