The Bosch Rexroth LINEAR-SET LSSDR2T-20-WV-500 (R109752080) is a comprehensive linear motion system designed to provide high precision and rigidity for various applications. This set includes a precision steel shaft with two ball guide grooves, complemented by two torque-resistant linear bushings. The shaft diameter is standardized as per the provided table, ensuring compatibility and ease of integration. The system is characterized by its steel precision tandem housing, which enhances the stability against cocking loads, an essential feature for maintaining accuracy in dynamic conditions. The hardened steel bearing plates are torquetransmitting and are set to zero clearance ex-works, which contributes to the system's high load capacity and reliability. Notably, this linear set is presented without external seals, making it suitable for environments where such seals are not required or could potentially interfere with operation. The absence of seals also simplifies maintenance and cleaning processes. With its robust construction, the LINEAR-SET LSSDR2T-20-WV-500 boasts a dynamic load capacity C that accounts for situations where both linear bushings are under equal load. The static load rating C ensures that minimal values are maintained even when the direction of loading cannot always be clearly defined. Additionally, it has a dynamic torsional moment load capacity Mt that further underscores its capability to handle varying operational demands. The permissible ambient temperature range indicates that this linear set can operate effectively within a specified thermal envelope, maintaining performance without compromising component integrity. Its maximum permissible linear speed vmax and max acceleration amax specifications denote its suitability for high-speed applications. Overall, weighing in at an efficient mass-to-performance ratio (mass m kg/m), this Bosch Rexroth linear motion system is an exemplary solution for applications requiring precise guidance with high torsional rigidity and load-bearing capacity.

| 1) | Load rating when both Linear Bushings are under equal load. The load ratings indicated are minimal values as the load direction cannot always be clearly defined. |
| 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. |

Reduced load capacity with short stroke
In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs .

Initial lubrication
Torque-resistant Linear Bushings do not come with initial lubrication. Grease Linear Bushings before use, see "Initial lubrication" in the "Lubrication" section.
Service life data is based on initial lubrication and relubricated Linear Bushings.
Lubricating a Linear Set with a torque-resistant compact Linear Bushing: on-shaft via Ø = 3.9 lubricating hole until lubricant seeps out. Lubricating a tandem Linear Set: on-shaft via recirculating lubricating groove in middle of outer diameter until lubricant seeps out. Lubricating a flanged Linear Set: on-shaft via funnel-type lube nipple recessed on the end face until lubricant seeps out.
