The Bosch Rexroth LINEAR-SET LSAS-B-20-DD (R107182020) is a high-quality linear set designed for precision linear motion applications. This product features a lightweight precision housing made from aluminum and includes a super linear bushing B, which does not have a self-alignment feature. The shaft diameter 'd' is specifically designed to fit with the provided components, ensuring smooth operation and stability. This linear set comes with two external seals that protect the internal mechanisms from contaminants while allowing for relubrication to maintain optimal performance over time. The standard version of this model is secured by a grooved taper pin, enhancing its reliability and durability in various applications. The LINEAR-SET LSAS-B-20-DD boasts impressive specifications such as dynamic load capacity and static load rating, which apply to the main direction of loading. It also has specific features like maximum permissible linear speed and acceleration, breakaway force, and a specified range of permissible ambient temperatures for operation. The product's friction force is noted for its dependency on speed and lubrication conditions when not under radial load. Furthermore, it has been tested to ensure longevity, with total travel ranging from 10^6 m to 10^7 m without failure under specified conditions. Its design allows it to absorb forces from all directions without reducing load capacity, making it an ideal choice for applications where loads may be exerted counter to the direction of opening. With an outer diameter D size H and weight specifications provided, this linear set is optimized for performance while maintaining a compact footprint. The Bosch Rexroth LINEAR-SET LSAS-B-20-DD is well-suited for use in various industrial applications where precise linear motion is required.

For absorbing forces from all directions without reducing the load capacity.

Loads exerted counter to the direction of opening with open Linear Bushings usually result in a considerable reduction in load capacity. In order to prevent this and facilitate the installation of specific open Linear Bushings, the lightweight Linear Set with side opening has been developed.

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 .

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.
