The Bosch Rexroth LINEAR-SET LSATO-A-30-DD (R108763020) is a high-quality linear motion set designed for applications that demand precise linear movement and high rigidity. This product features a lightweight precision tandem housing made from aluminum, which houses two super linear bushings A and incorporates external seals. The set is designed to be relubricatable, ensuring long-term performance and ease of maintenance. Equipped with a shaft diameter 'd' that allows for clamped fastening, this linear set provides a self-alignment feature that is part of the Series Super A. It offers low frictional drags due to its integrated wiper seals on both sides, which are effective even when not under radial load. The dynamic load capacity 'C' indicates the system's ability to handle load capacities equally across both bushings in the main direction of loading. For environments with varying temperatures, the LINEAR-SET LSATO-A-30-DD operates within an ambient temperature range of -20°C to +80°C. Its design accommodates maximum acceleration 'amax' and can achieve a breakaway force that ensures smooth initiation of movement. The system's static load rating 'C' ensures stability even when stationary loads are applied. With an outer diameter 'D', this linear set can support long guides while maintaining a high level of rigidity necessary for precise operations. Its dynamic longitudinal moment load capacity 'ML' and static longitudinal moment load capacity further contribute to its robust performance in various applications. The LINEAR-SET LSATO-A-30-DD has been tested for total travel distances significantly large without failure, highlighting its durability and reliability. Weighing only 0.7 kg, it presents an efficient solution for systems requiring light yet sturdy components. Additionally, it is available as a Linear Motion Slide, offering versatility for different deployment scenarios where guided linear motion is required.

Impact of load direction on load rating of open Linear Bushings

The load ratings C and C0 apply for the main direction of loading ρ = 0°. For all other load directions, the load ratings must be multiplied by the factors fρ (dynamic load rating C) or fρ0 (static load rating C0).

Installing specific Linear Bushings can prevent reductions in load capacity (see Linear Set with side opening).

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.
