The Bosch Rexroth LINEAR-SET LSAS-A-40-DD (R107164020) is a state-of-the-art linear motion system designed for precision applications where high accuracy and low friction movement are required. This linear set is constructed from lightweight aluminum, providing a sturdy yet nimble solution for various linear motion needs. The unit features an advanced super linear bushing A with a self-alignment feature, ensuring smooth operation and enhanced performance. Equipped with two external seals, the LSAS-A-40-DD is protected against contaminants, thereby extending the service life of the system. It also offers easy maintenance with its relubricatable design. The grooved taper pin secures the assembly, ensuring stability and reliability in operation. With a shaft diameter of 40mm, this linear set has been engineered to accommodate a wide range of loads while maintaining precision. The system boasts impressive specifications such as high dynamic load capacity and static load rating, which apply to the main direction of loading. The permissible ambient temperature range ensures that it can operate effectively in various environmental conditions without degradation of performance. Moreover, it can handle maximum accelerations and speeds without failure, with tests showing total travel from 10^6 m to 10^8 m. The LINEAR-SET LSAS-A-40-DD is particularly suited for applications requiring absorption of forces from all directions without compromising load capacity. Its design counters potential reductions in load capacity that could occur when forces are exerted counter to the direction of opening with open Linear Bushings. Overall, Bosch Rexroth's LINEAR-SET LSAS-A-40-DD offers a robust solution for sophisticated linear motion tasks where durability, precision, and low maintenance are paramount. Its well-thought-out features make it an ideal choice for those seeking reliable linear guidance systems.

See the notes on installing Linear Sets with side opening.

For load in the direction of opening, please refer to the loading diagrams (see "Diagrams" section).

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-R107164020-Linear set (aluminum), S-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.

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.

Notes on installing Linear Sets with side opening

No reference edges:

Straighten the first shaft using the shaft support rail and fasten it in place. Align the second shaft parallel to the first and fasten it in place. Slide the Linear Sets onto the shaft and fasten them to the machine table.

With reference edges:

Press the first shaft with shaft support rail onto the reference edge and fasten the shaft support rail in place. Align the second shaft parallel to the first and fasten the shaft support rail in place. Slide the Linear Sets onto the shafts. Next: with one reference edge on the machine base and one on the machine table: Press the Linear Sets on the first shaft onto the reference edge of the machine table and fasten into place. Fasten the Linear Sets on the second shaft to the machine table. with just one reference edge on the machine base: Fasten Linear Sets to the machine table.
