The Bosch Rexroth LINEAR-SET LSAT-A-16-DD (R108561620) is a high-quality linear motion set designed for precision applications. This product features a lightweight precision tandem housing made from aluminum, incorporating two super linear bushings A with self-alignment capabilities, which ensure smooth and accurate movement. The set includes external seals and is relubricatable, extending the maintenance intervals and service life of the system. With a shaft diameter of 16 mm, this linear set is equipped to handle dynamic load capacities with ease while maintaining stability and performance. The tandem configuration, closed design, and inclusion of two seals contribute to its robustness and reliability in various operational conditions. It has been engineered to achieve maximum acceleration and can withstand a wide range of ambient temperatures from -20°C to +80°C. The outer diameter of the bushings is specified for size H, which also defines the breakaway force needed to initiate motion. The LINEAR-SET LSAT-A-16-DD boasts an impressive static load rating and dynamic longitudinal moment load capacity that ensures it can support significant loads without compromising functionality. The product is suitable for applications requiring precise guiding with easy installation due to its fixed working bore diameter. Its friction force characteristics have been optimized to minimize resistance under no radial load conditions, promoting energy efficiency during operation. Moreover, it has been tested for total travel distances ranging significantly without failure, demonstrating its durability. With the capability of reaching speeds up to 5 m/s, albeit with limited service life due to increased wear on plastic parts at higher velocities, this linear set maintains performance across a spectrum of speed requirements. It also offers versatility as it's available as a Linear Motion Slide for different application needs. Weighing in at 0.2 kg for size L, it provides a balance between strength and lightness making it an excellent choice for various precision-guided tasks that demand reliability and accuracy.

1) Load rating when both Linear Bushings are under equal load. The load ratings apply for the main direction of loading. If the load direction is not the main direction of loading, the dynamic load ratings must be multiplied by the following factors:Ø d 10 to 16: f = 0.82, f0 = 0.86,Ø d 20 to 50: f = 0.82, f0 = 0.78
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

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.

Life expectancy calculation

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.
