The Bosch Rexroth LINEAR-SET LSK-12-DD (R106021200) is a sophisticated linear motion component designed for precision applications. This linear set features a standard pillow block housing constructed from reinforced PA, providing a lightweight yet stable platform for linear movement. The segmental linear bushing is made of durable plastic and includes two interchangeable wiper seals that ensure protection against contaminants while maintaining smooth operation. With a shaft diameter of "d," the LSK-12-DD linear set is engineered to offer adjustable radial clearance, allowing users to minimize play and achieve zero-clearance for high-precision tasks. The friction force of this model is specifically tailored to maintain efficiency, with the frictional drags being influenced by the speed of operation and lubrication conditions. The dynamic load capacity C indicates minimal values due to the variability in loading orientation and direction. However, these values are critical for understanding the limits of the product under different operational stresses. The static load rating C provides insights into the maximum stationary load that can be sustained by the bushing without causing permanent deformation. This linear set operates effectively within a specified temperature range, ensuring reliability even in varying environmental conditions. The maximum permissible linear speed vmax and max acceleration amax are indicative of its capability to handle rapid movements without compromise to stability or performance. Designed as a closed format for its linear bushings, the LINEAR-SET LSK-12-DD ensures that internal components are safeguarded against external elements which could otherwise impact its functionality. Whether used in automated equipment or precise manual adjustments, this Bosch Rexroth product stands out for its adaptability and precision in facilitating smooth linear motion.

Effect of load direction on load rating

The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used.

Reduced load capacity with short stroke

In case of a short stroke, the service life of the shaft is less than that of the segmental Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .

Selection guide for operation under difficult conditions

For constantly humid or damp conditions caused, for instance, by water-based coolants/lubricants, we recommend the stainless steel Linear Bushing with parts made of steel in accordance with ISO 683-17 / EN 10088.

Life expectancy calculation

General mounting instructions

Linear sets with segmental Linear Bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service life data is based on initial lubrication and relubricated Linear Bushings.
