The Bosch Rexroth LINEAR-SET LSFDR2-50-WV-900 (R072355085) is a high-precision linear motion set designed for various industrial applications that require smooth and accurate guidance. This linear set is composed of a steel flanged sleeve and a shaft, offering a robust and compact solution for linear movement. The product features ball guide grooves that ensure stable motion, with one groove provided for diameter shafts and two grooves for larger diameter shafts. The LINEAR-SET LSFDR2-50-WV-900 is specifically engineered without seals, making it suitable for environments where external sealing is not critical. The standard steel construction provides durability, while the torqueresistant design of the compact linear bushing ensures high resistance to torsional loads. Hardened steel bearing plates are pre-set to zero clearance by the manufacturer to facilitate precise operation right from installation. This model boasts a dynamic load capacity (C) and can handle maximum accelerations (amax), as well as operate within a permissible ambient temperature range of -20°C to 80°C. It can achieve maximum linear speeds (vmax) without compromising performance. The static load rating (C0) and dynamic torsional moment load capacity (Mt) further define its capabilities in static and dynamic conditions. With a weight of 1.3 kg/m, the LINEAR-SET LSFDR2-50-WV-900 is relatively lightweight given its robustness. It also offers features such as stability against cocking loads and relubrication capability, which extend its service life and maintain efficiency over time. In summary, the Bosch Rexroth LINEAR-SET LSFDR2-50-WV-900 provides reliable linear motion with its high-quality construction and design features tailored for demanding industrial applications where precision movement is essential.

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 .

| 2) | s = movement path |

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.
