The Bosch Rexroth LINEAR-SET LSAO-A-16-DD (R103761620) is a high-quality linear motion product designed for applications that demand precise and smooth linear movement. This linear set consists of an aluminum housing with a super linear bushing A, which features a self-aligning capability to ensure optimal performance. The shaft diameter 'd' is complemented by two external seals that protect the internal mechanism from contaminants, enhancing the durability and reliability of the set. The lightweight precision housing is made from aluminum, making it ideal for applications where weight is a concern without sacrificing strength or precision. The bushing is secured by a grooved taper pin and offers the convenience of being relubricatable, which allows for easy maintenance and extended service life. The LINEAR-SET LSAO-A-16-DD is equipped with integrated wiper seals on both sides to reduce frictional drags, which are dependent on speed and lubrication conditions. It boasts an impressive dynamic load capacity and static load rating, ensuring it can handle the demands of various loading directions. The maximum acceleration (amax) and permissible ambient temperature range demonstrate its capability to operate in diverse environmental conditions. With an outer diameter 'D', this linear set provides a rigid solution for long guides requiring shaft support. Its breakaway force and maximum permissible speed (vmax) indicate its ability to perform at high speeds, with tests showing total travel ranging from 10^4 m to 10^5 m without failure, although service life may be limited due to wear on plastic parts under such conditions. Overall, this product offers exceptional performance for its size class with specifications tailored for demanding applications requiring precise linear guidance with high rigidity and reliability.

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-R103761620-Linear set (aluminum), O-A-16, 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.
