The Bosch Rexroth LINEAR-SET LSGOE-A-25-DD (R106862540) is a high-precision linear motion system designed for various applications that require smooth and accurate linear movement. This linear set is composed of a steel linear bushing and shaft, with an open, adjustable design that allows for fine-tuning to achieve zero-clearance or preloaded guides. It features Bosch Rexroth's Super LB A, which is a spheroidal graphite cast ironsteel super linear bushing with a self-alignment feature, enhancing the performance by accommodating misalignment in the system. Equipped with integrated wiper seals on both sides, the LINEAR-SET LSGOE-A-25-DD ensures contamination protection for the internal components, while also contributing to frictional drags. These drags are dependent on speed and lubrication conditions when the radial load is absent. The set comes clamped to h6 shaft lower limit and can handle dynamic load capacities effectively in its main direction of loading. The unit boasts an impressive static load rating C and can endure maximum accelerations (amax), ensuring reliable operation under various conditions. It operates within a permissible ambient temperature range from -20°C to +80°C without compromising functionality. The outer diameter D of the bushing allows for easy installation into different setups. Designed for longevity, tests have indicated that this model can sustain total travel distances significantly high without failure, although service life may be limited due to increased wear on plastic parts at higher speeds. With speeds up to 5 m/s possible, this LINEAR-SET provides versatility for numerous applications. The product's weight stands at 0.71 kg, offering a sturdy yet manageable component for integration into machinery or equipment. The adjusting screw included in the design facilitates radial clearance adjustments post-installation. Overall, the Bosch Rexroth LINEAR-SET LSGOE-A-25-DD represents a robust solution for those needing precise linear guidance in their mechanical systems or automation projects.

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-R106862540-Linear set (steel), OE-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.
