The Bosch Rexroth LINEAR-SET LSADR2-50-WV-1200 (R109855087) is a high-precision, lightweight linear motion set designed to provide smooth and accurate linear movement in various applications. This product is comprised of a precision steel shaft with two ball guide grooves and a torqueresistant linear bushing, ensuring stability against cocking loads and efficient torque transmission. The hardened steel bearing plates are set to zero clearance ex works, contributing to the system's high accuracy and rigidity. The shaft diameter (d) is included as standard length according to the provided table, catering to specific application needs. Notably, this model comes without an external seal, making it suitable for environments where direct contact with debris or particulates is minimal. Nevertheless, it remains relubricatable for easy maintenance and longevity of the system. A standout feature of this LINEAR-SET is its construction from aluminum for the tandem housing, which not only contributes to its torqueresistance but also minimizes the overall weight of the assembly. This makes it an ideal choice for designs where mass is a critical factor without compromising on strength or performance. With dynamic load capacity C and static load rating C indicated as minimal values due to variable loading directions, this set ensures reliability under different operational conditions. It can withstand maximum permissible linear speeds (vmax) and accelerations (amax), while operating within a permissible ambient temperature range. The LSADR2-50-WV-1200 model's size specifications such as outer diameter D (Size E), length L, and weight are meticulously crafted to meet stringent requirements. Its dynamic torsional moment load capacity (Mt) further underscores its capability in handling varying torsional forces during operation. In summary, this Bosch Rexroth linear set stands out for its combination of lightweight design, precise movement control, and durable construction—tailored for sophisticated linear motion tasks that demand high accuracy and efficiency.

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.
