The Bosch Rexroth LINEAR-SET LSAO-B-30-DD (R103783020) is a high-quality linear motion set designed for applications requiring precise and smooth linear movement. This product features a lightweight precision housing made of aluminum and includes a super linear bushing B, which lacks a self-alignment feature, ensuring stable and accurate motion control. The shaft diameter is tailored to fit specific requirements, and the set comes equipped with two external seals that provide additional protection against contaminants. The LINEAR-SET LSAO-B-30-DD is secured by a grooved taper pin for reliable fastening and is relubricatable for easy maintenance. It offers a standard version with a radial shaft clearance classified under size V, which signifies its dimensional category. The friction force FR noted in the specifications relates to the frictional drags generated by the linear bushings with integrated wiper seals when not under radial load; these frictions vary depending on speed and lubrication conditions. With regard to load capacities, this linear set has both dynamic and static ratings that apply to the main direction of loading, ensuring it can handle specified forces during operation. The maximum acceleration (amax), permissible ambient temperature range, outer diameter (D), breakaway force, maximum permissible linear speed (vmax), and static load rating (C) are all defined within the product specifications to ensure optimal performance within its operating parameters. The LINEAR-SET LSAO-B-30-DD is suitable for long guides that require shaft support and exhibit high levels of rigidity. Its design allows for speeds of up to 5 m/s; however, service life may be limited due to increased wear on plastic parts at higher speeds. Tests indicate that total travel ranging from 10^4 m to 10^5 m can be achieved without failure. The product's weight is also specified for reference in applications where mass could influence design or functionality. Overall, this Bosch Rexroth linear set provides robust construction and reliable performance for demanding linear motion tasks in various applications where precision movement is essential.

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.
