The Bosch Rexroth LINEAR-SET LSACT-12-DD-NR-G (R102921234) is a high-performance linear motion set designed for precision applications. This set includes a lightweight precision tandem housing made from aluminum and features two compact linear bushings, model KBCNR, which are integrated with wiper seals for enhanced protection against contaminants. The shaft diameter is denoted as 'd,' and the assembly comes with two seals for additional sealing effectiveness. The LINEAR-SET LSACT-12-DD-NR-G is engineered to be rust-resistant and is pre-greased with Dynalub for reduced maintenance and longevity. It offers normal radial clearance and is suitable for a variety of linear motion tasks requiring high accuracy and reliability. With its dynamic load capacity C, the set can sustain significant loads in the main direction of loading, while alternative load directions require adjustment factors to be applied to ensure proper load capacities. The static longitudinal moment load capacity ML further underscores the robustness of this linear set in stationary applications. This product boasts a maximum acceleration (amax), indicating its capability to handle rapid movements within its operational parameters. It operates efficiently within a permissible ambient temperature range, ensuring reliable performance across different environments. The outer diameter D is specified to match the system requirements, while the size H indicates the breakaway force necessary to initiate movement. The maximum permissible linear speed (vmax) showcases the swift motion capabilities of this linear set. Bosch Rexroth's LINEAR-SET LSACT-12-DD-NR-G also has a noted static load rating C and friction force that provide insights into its mechanical resistance characteristics during use. Weighing in at 'weight' value, this product from Bosch Rexroth's product group ID offers an ideal balance between strength and mass, making it suitable for various applications where weight and performance are critical factors. Its closed format for linear bushings ensures durability and consistent operation over time.

1) The load ratings apply for the main direction of loading. If the load direction is not the main direction of loading, the load ratings must be multiplied by the following factors: Ø d 12 and 16: f = 0,90, f0 = 0.86, Ø d 20 to 50: f = 0.79, f0 = 0.68
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

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 short stroke, the service life of the shafts is less than that of Linear Bushings. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
