The Bosch Rexroth LINEAR-SET LSGO-A-25-DD (R106762540) is a high-precision linear motion set designed for applications requiring accuracy, rigidity, and durability. This product includes a standard precision housing made of spheroidal graphite cast iron and features the super linear bushing A with a self-alignment feature, which ensures smooth and precise linear motion. The set is equipped with integrated wiper seals on both sides to protect against contaminants, enhancing the longevity of the system. The LINEAR-SET LSGO-A-25-DD boasts a shaft diameter 'd' that provides a secure fit while allowing for maximum acceleration (amax) without compromising performance. It can operate within an ambient temperature range from 'C min' to 'C max', ensuring reliability across various working environments. The outer diameter 'D' has been optimized for compatibility with standard mounts. This linear set's dynamic load capacity 'C' indicates its ability to handle loads effectively in the main direction of loading, while the static load rating 'C' reflects its capacity to maintain performance under constant loads without motion. The breakaway force and maximum permissible linear speed (vmax) are testament to its capability to operate at high speeds up to 'ms max', although service life may be limited due to wear on plastic parts under such conditions. Weighing in at only '.', this product is suitable for long guides that require additional shaft support and exhibit a high level of rigidity. Its design is particularly beneficial for systems where frictional drags need to be minimized, as indicated by the footnote regarding friction force FR. Overall, the Bosch Rexroth LINEAR-SET LSGO-A-25-DD is an ideal solution for applications that demand precise linear guidance with minimal maintenance requirements. Its robust construction and advanced features make it suitable for a wide range of industrial applications where accuracy and reliability are paramount.

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-R106762540-Linear set (steel), O-A-25, 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.
