The Bosch Rexroth LINEAR-SET LSAE-A-30-DD (R103663020) is a high-quality linear motion set designed for various applications requiring precise and smooth linear movement. The set includes an aluminum lightweight precision housing with a super linear bushing A, which features self-alignment capabilities, ensuring optimal performance even in misaligned installations. The shaft diameter 'd' is accompanied by two external seals that offer protection against contamination, thereby extending the service life of the unit. This linear set is adjustable and relubricatable, catering to maintenance requirements and providing flexibility in use. It boasts a standard version with remarkable dynamic load capacity C and static load rating C, which are critical for sustaining loads during operation. These capacities are specific to the main direction of loading; however, they can be adjusted with multiplication factors provided for non-main direction loads. The LINEAR-SET LSAE-A-30-DD operates efficiently within a permissible ambient temperature range and can handle maximum accelerations (amax) without compromising integrity. It also features an outer diameter D suitable for its size category H, along with a specified breakaway force necessary to initiate movement. The maximum permissible linear speed (vmax) indicates the swift motion capabilities of the set while maintaining its longevity, as evidenced by extensive travel tests without failure. Additionally, this model has been engineered to offer minimal frictional drag under no radial load conditions and comes pre-clamped to ensure zero-clearance or preloaded guides upon delivery. The adjusting screw included allows for easy radial clearance adjustments when required. With its weight optimized for balance between sturdiness and ease of handling, the Bosch Rexroth LINEAR-SET LSAE-A-30-DD proves to be an excellent choice for those in need of reliable linear motion solutions.

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 .
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.
