The Bosch Rexroth LINEAR-SET LSG-A-12-DD (R106561240) is a high-quality linear motion set designed for precision applications requiring smooth and accurate guidance. This product features a closed linear bushing of size V from the Super A series, which includes an integrated self-alignment feature that enhances movement accuracy and reduces installation time. The set is comprised of a steel linear set with two seals, ensuring durability and protection against contaminants. The lamellar graphite cast iron housing provides a sturdy foundation for the super linear bushing A, which operates with a standard precision level. The shaft diameter 'd' is engineered for fixed working bore diameters, facilitating straightforward installation. Integrated wiper seals on both sides of the bushing minimize frictional drags when not under radial load, though these frictions can vary depending on speed and lubrication conditions. The LINEAR-SET LSG-A-12-DD boasts an impressive dynamic load capacity (C), tailored to withstand the main direction of loading. Should loading occur in other directions, the load capacities can be adjusted by applying specific factors detailed in the product specifications. This set can handle maximum accelerations (amax) and operate within ambient temperatures ranging from -20°C to +80°C without performance degradation. With an outer diameter (D) designed to accommodate various applications, this product also specifies breakaway force requirements and maximum permissible linear speeds (vmax), with potential speeds reaching up to 5 m/s. However, it's important to note that at such high speeds, service life may be reduced due to increased wear on plastic components. This Bosch Rexroth linear set has been tested extensively, indicating total travel distances ranging from 100 km to 1000 km without failure under specified conditions. The static load rating (C0) ensures stability under stationary loads, while the weight of 0.3 kg makes it suitable for various industrial applications requiring precise linear movement. The LINEAR-SET LSG-A-12-DD is an ideal choice for those seeking reliable performance in their linear motion systems.

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.

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.
