The Bosch Rexroth LINEAR-SET LSACT-20-DD-NR-G (R102922034) is a high-precision linear motion set designed for various applications requiring smooth and accurate linear movement. This set features a lightweight precision tandem housing made from aluminum, which includes two compact linear bushings KBCNR, ensuring a durable and reliable motion system. The shaft diameter is specifically designed to provide a seamless fit with the accompanying components. Equipped with integrated wiper seals, the LINEAR-SET LSACT-20-DD-NR-G offers protection against contaminants, thereby extending the life of the system. These seals also contribute to the frictional drags generated by the linear bushings when not under radial load, which are dependent on speed and lubrication conditions. The system's rust-resistant version and initial lubrication with Dynalub highlight its readiness for use in various environments while reducing maintenance needs. It is capable of handling dynamic load capacities effectively, with specific factors provided for non-main direction loading scenarios to ensure correct application. With a permissible ambient temperature range from -20°C to +80°C, this Bosch Rexroth linear set can operate in diverse working conditions. It has been engineered for maximum acceleration and speed, featuring an outer diameter D that complements its design specifications for optimal performance. The LINEAR-SET LSACT-20-DD-NR-G also provides static load ratings and breakaway force details for size H, ensuring users understand its capabilities in static conditions. Its weight has been optimized to contribute to overall equipment efficiency without sacrificing strength or stability. Overall, this product is part of Bosch Rexroth's commitment to delivering advanced linear guide solutions that meet rigorous demands across various applications while maintaining precision and longevity.

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 .

| 2) | s = stroke |
