The Bosch Rexroth LINEAR-SET LSSOE-A-12-DD (R106861240) is a high-precision linear motion system designed to facilitate smooth and accurate linear movement in various applications. This particular model features a steel linear set with an open, adjustable design, incorporating Bosch Rexroth's superior LB A super linear bushing with a self-alignment feature. The shaft diameter 'd' is meticulously crafted to ensure compatibility and performance, while the integration of two seals enhances the system's reliability by protecting against contaminants. Constructed with a standard precision housing made from spheroidal graphite cast iron, this LINEAR-SET is engineered for durability and longevity. The steel super linear bushing A is secured with a locating screw and includes integrated wiper seals that contribute to its maintenance of cleanliness and efficiency. The product's outer diameter 'D', breakaway force, maximum permissible linear speed 'vmax', dynamic load capacity 'C', static load rating 'C', radial clearance specifications, and weight are all optimized for top-tier performance. Equipped to handle maximum accelerations 'amax' and operating within a permissible ambient temperature range, the LINEAR-SET LSSOE-A-12-DD ensures reliability under various environmental conditions. Its design allows for speeds of up to 5 m/s; however, service life may be limited due to increased wear on plastic parts under such conditions. This model has been tested extensively for travel distances ranging significantly without failure, showcasing its robustness. The product comes clamped to an h6 shaft lower limit and set to zero-clearance as part of its default configuration. For applications requiring zero-clearance or preloaded guides, an adjusting screw is provided for fine-tuning radial clearance. This makes the LINEAR-SET LSSOE-A-12-DD versatile for use in precise applications where minimal play is essential. Its identification within the product group ID signifies its place within Bosch Rexroth's lineup of premium linear motion products.

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 .
| 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.

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.
