The Bosch Rexroth LINEAR-SET LSGE-A-30-DD (R106663040) is a comprehensive linear motion system designed for precision and durability. This linear set is crafted from steel and features an adjustable super linear bushing A with a self-alignment feature, ensuring smooth and accurate motion. The lamellar graphite cast iron housing provides robust support, while the integrated wiper seals on both sides maintain cleanliness by preventing the ingress of contaminants, which is essential for maintaining the system's integrity and prolonging its service life. With a shaft diameter of 30 mm, this model comes equipped with two seals that contribute to its normal precision rating. The set is engineered to handle dynamic load capacities effectively, with specific load capacity values depending on the direction of loading. For instance, certain factors need to be applied if the loading direction deviates from the main direction. The LINEAR-SET LSGE-A-30-DD can withstand maximum accelerations (amax) and operate within a permissible ambient temperature range, ensuring reliability across various working conditions. The outer diameter D and breakaway force are specified to meet application requirements, while the maximum permissible linear speed (vmax) highlights its capability for high-speed operations. This product also boasts an impressive static load rating C and comes clamped to an h6 shaft lower limit with zero-clearance pre-set. It is suitable for applications requiring precise guidance with minimal frictional drag, which is quantified in the provided specifications. The weight of the unit is carefully considered to balance durability with ease of handling, making it ideal for various industrial applications. Additionally, it features an adjusting screw for radial clearance adjustments to achieve zero-clearance or preloaded guides as needed by specific applications. With its comprehensive design and robust build quality, this Bosch Rexroth linear set ensures reliable performance in demanding 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.
