The Bosch Rexroth LINEAR-SET LSATOE-A-40-DD (R103464020) is an advanced linear motion technology component designed for precise and smooth linear movement. This product is a lightweight precision tandem housing made from aluminum, featuring two super linear bushings A that ensure high accuracy and load capacity. It is characterized by its tandem, open, adjustable configuration with a reference edge and external seals that provide additional protection against contaminants. The LSATOE-A-40-DD is relubricatable, enhancing its longevity and performance in various applications. The integrated wiper seals produce frictional drags which are dependent on the speed and lubrication conditions but are minimized when the system is not under radial load. The dynamic and static load capacities of this linear set are optimized when both bushings are under equal load, ensuring stability and reliability in the main direction of loading. This model comes with a shaft diameter 'd' that has been clamped to the h shaft lower limit and set to zero-clearance to eliminate play within the system. It also includes an adjusting screw for adjusting radial clearance to accommodate different application requirements. The LINEAR-SET LSATOE-A-40-DD can withstand a wide range of ambient temperatures and is capable of handling maximum permissible linear speeds up to a certain threshold, although service life may be limited at these higher speeds due to increased wear on plastic parts. With its series Super A self-alignment feature, this product can compensate for alignment errors, which is particularly useful in complex installations or where precision alignment is challenging. Additionally, this model has been tested for total travel ranging from several million meters without failure, attesting to its durability and robustness. Overall, the Bosch Rexroth LINEAR-SET LSATOE-A-40-DD offers exceptional performance for applications requiring precise linear motion with high reliability and ease of maintenance. Its design also allows it to be used as a linear motion slide if needed.

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.
