The Bosch Rexroth LINEAR-SET LSAO-B-16-DD (R103781620) is a high-quality linear motion set designed for applications requiring precise and smooth linear movement. This set includes an aluminum lightweight precision housing with a super linear bushing B, which lacks a self-alignment feature, ensuring stable and accurate operation. The shaft diameter is designed to accommodate specific application needs, and the inclusion of two external seals provides added protection against contaminants, enhancing the longevity of the system. The LINEAR-SET is characterized by its open design and is secured by a grooved taper pin, making installation and maintenance straightforward. The ability to relubricate the system contributes to its reliability and extended service life. It operates within a permissible ambient temperature range, making it suitable for various working environments. This model boasts a standard version that emphasizes reduced weight without compromising on rigidity or load capacity. The dynamic load capacity indicates how much weight the set can handle during motion, while the static load rating reflects its ability to sustain loads when stationary. Its breakaway force ensures minimal initial resistance when starting movement. The Bosch Rexroth LINEAR-SET is capable of achieving maximum accelerations and can handle speeds up to a specified limit; however, it should be noted that excessive speed may result in increased wear on plastic components. Tests have demonstrated impressive travel ranges without failure under proper conditions. Designed for long guides that require shaft support with high rigidity, this linear set's weight has been optimized for such applications. Its friction force characteristics are influenced by speed and lubrication conditions but are designed to minimize drag for efficient operation. Overall, this product offers a robust solution for those in need of reliable linear motion hardware with specific performance capabilities.

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.
