The Bosch Rexroth LINEAR-SET LSADR2-25-WV-2000 (R109852588) is a high-quality linear motion set designed for precision applications. This product features a lightweight precision tandem housing made of aluminum, which provides excellent stability and resistance to cocking loads. It is equipped with a precision steel shaft that includes two ball guide grooves, ensuring torqueresistant movement and enhancing the overall rigidity of the system. The shaft diameter 'd' is standard as per the provided table, and it comes with the shaft included, facilitating ease of installation and maintenance. The linear set is designed without external seals, making it suitable for environments where such protection is not critical. Furthermore, it can be relubricated to extend its service life and maintain smooth operation over time. This LINEAR-SET model boasts a dynamic load capacity 'C' that represents minimal values due to varying loading directions. It also features hardened steel bearing plates that have been set to zero clearance ex works to ensure precise movement without play. The maximum permissible ambient temperature range for this product extends from 'min prefixprefixsuffixsuffix' degrees Celsius to 'max prefixprefixsuffixsuffix' degrees Celsius, allowing for operation in a wide range of conditions. Additionally, the LSADR2-25-WV-2000 can handle a maximum acceleration 'amax' and exhibits a static load rating 'C', ensuring reliable performance under stationary loads. Its dynamic torsional moment load capacity 'Mt' further attests to its robustness in applications involving rotational forces. The outer diameter 'D', size 'E', and weight specifications are optimized for seamless integration into various setups. The mass per meter 'kg/m' indicates the lightweight nature of this linear set, making it an ideal choice for applications where weight savings are crucial without compromising on strength or performance. In summary, this Bosch Rexroth linear motion set provides a torqueresistant solution with exceptional precision and durability for various industrial applications requiring accurate linear movement.

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.
