The Bosch Rexroth LINEAR-SET LSSDR2T-20-WV-2000 (R109752088) is a robust linear motion set designed for high precision and rigidity in various applications. This product encompasses a precision steel shaft with two ball guide grooves, and it comes with two torque-resistant linear bushings. These bushings are pre-set to zero clearance by the manufacturer, ensuring optimal performance from the outset. The steel tandem housing adds to the system's overall durability and stability, particularly against cocking loads. The LINEAR-SET LSSDR2T-20-WV-2000 is specially designed without external seals, which makes it suitable for environments where seals are not necessary or could potentially interfere with operation. Its dynamic load capacity ensures that it can handle significant operational demands, and the static load rating confirms its ability to maintain performance under constant loads. With a shaft diameter of 20mm and a standard length of 2000mm, this linear set is well-suited for applications requiring precise linear movement over a considerable distance. The hardened steel bearing plates contribute to the system's ability to transmit torque efficiently while maintaining alignment and reducing wear. The product operates effectively within a permissible ambient temperature range, highlighting its versatility in different working conditions. Additionally, its maximum acceleration and permissible linear speed specifications indicate its capability for high-speed applications without compromising on accuracy or reliability. Overall, the Bosch Rexroth LINEAR-SET LSSDR2T-20-WV-2000 is an advanced solution for users requiring precise and stable linear motion in their mechanisms or machines. With its carefully designed components and material quality, this linear set stands out as a reliable option for various industrial applications.

| 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.
