The Bosch Rexroth LINEAR-SET LSADR2T-20-WV-900 (R109952085) is a high-quality linear motion set designed for precise and smooth motion in various applications. This set includes a lightweight precision tandem housing made of aluminum and a precision steel shaft with two ball guide grooves, which are essential for maintaining the accuracy of the system. The shaft diameter 'd' comes in standard lengths as per the provided table, ensuring compatibility with different setups. Equipped with two torque-resistant linear bushings, the LSADR2T-20-WV-900 is capable of transmitting forces without compromising stability. These bushings are set to zero clearance ex works, allowing for immediate installation without the need for additional adjustments. The hardened steel bearing plates enhance durability and ensure that the system can withstand high torsional loads. This linear set is designed to resist cocking loads efficiently due to its robust construction. It also features external seals and is relubricatable, extending its operational lifespan by facilitating easy maintenance. The dynamic load capacity C indicates minimal values as loading directions can vary; however, it ensures that both linear bushings share an equal load to optimize performance. The Bosch Rexroth LSADR2T-20-WV-900 operates within a permissible ambient temperature range and can handle maximum accelerations (amax) without faltering. Its outer diameter 'D' and size 'E' specifications are tailored to fit specific requirements, while its mass 'm kg/m' reflects its lightweight design that does not sacrifice strength or functionality. In summary, this linear set is suitable for applications requiring high precision and resistance to torsional forces. Its dynamic torsional moment load capacity (Mt), along with other specified capabilities such as static load rating (C) and maximum permissible linear speed (vmax), makes it an optimal choice for systems demanding reliability and precision in their linear motion components.

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.
