The Bosch Rexroth LINEAR-SET LSAO-A-40-DD (R103764020) is a high-quality linear motion set designed for applications requiring precise and smooth linear movement. This set includes a lightweight precision housing made from aluminum and features a super linear bushing A with a self-alignment feature, which ensures optimal performance even under misaligned conditions. The bushings are secured by grooved taper pins and come with external seals that protect against contaminants, contributing to the system's reliability and longevity. The LINEAR-SET LSAO-A-40-DD is capable of handling dynamic load capacities, making it suitable for various loading directions. Its design incorporates two integrated wiper seals on each side to minimize frictional drag, which is dependent on speed and lubrication conditions. The set can withstand maximum accelerations and operates efficiently within a wide range of ambient temperatures. With an open format for the linear bushings, this product offers ease of maintenance including relubrication capabilities to extend service life. It has been tested to ensure durability, with total travel ranging significantly without failure. Furthermore, the set is designed to support long guides that require shaft support and exhibit high levels of rigidity. This Bosch Rexroth linear motion set is ideal for applications needing reliable linear guidance with high rigidity and precision. Its construction allows for speeds up to a certain limit; however, service life may be limited by increased wear on plastic parts at higher speeds. The LINEAR-SET LSAO-A-40-DD also boasts an impressive static load rating, ensuring stability under stationary loads. Overall, this Bosch Rexroth product offers robust performance characteristics suitable for demanding linear motion applications while maintaining a compact form factor due to its aluminum construction. With its combination of features such as self-alignment, relubrication capability, and durable seals, it provides an effective solution for precise motion control in various industrial settings.

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 .

technical illustration-R103764020-Linear set (aluminum), O-A-40, with two seals

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.
