The Bosch Rexroth LINEAR-SET LSAO-B-50-DD (R103785020) is a high-quality linear motion system designed for applications requiring precise and smooth linear movement. This linear set comprises an aluminum housing, open type, with a lightweight precision housing and a super linear bushing B that lacks a self-alignment feature. The shaft diameter 'd' ensures compatibility with various installations, while the inclusion of two external seals protects against contaminants and enables relubrication, extending the system's service life. The LINEAR-SET LSAO-B-50-DD is designed to be secured by a grooved taper pin and features clamped fastening for robust attachment in dynamic environments. It boasts a standard version that strikes a balance between performance and durability. The product's static load rating C and dynamic load capacity C are indicative of its ability to handle significant loads in the main direction of loading, making it suitable for long guides that require shaft support and high rigidity. With maximum acceleration amax specifications, the system can handle rapid movements without compromising stability or performance. It operates efficiently within a permissible ambient temperature range, ensuring reliability across different working conditions. The outer diameter D is tailored to fit seamlessly into various design configurations. The LINEAR-SET can reach maximum permissible linear speeds vmax, with potential speeds up to 5 m/s, although this is limited by increased wear on plastic components over time. Nevertheless, tests have indicated impressive total travel distances without failure. Its breakaway force and frictional drags are optimized for minimal resistance when not under radial load. Weighing in at . kg, this Bosch Rexroth linear set provides an excellent balance between weight and structural integrity. It is particularly well-suited for applications where extended service life and low maintenance are critical due to its relubricatable design and robust construction capable of withstanding demanding operational conditions.

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.
