The Bosch Rexroth LINEAR-SET LSHDR2T-50-WV-900 (R072255085) is a high-precision linear motion set designed for various applications requiring smooth and accurate linear movement. This product features two torque-resistant compact linear bushings, integrated into a standard compact steel sleeve, which ensures stability against cocking loads and enables efficient torque transmission. The set comes with hardened steel bearing plates that have been pre-set to zero clearance by the manufacturer, enhancing the system's precision. The LINEAR-SET is equipped with ball guide grooves suitable for shafts with diameters of 50 mm and above, ensuring reliable guidance and load distribution. It also includes a keyway for effective torque transmission. The product's design omits external seals to maintain a streamlined profile while remaining relubricatable to extend its service life. With a dynamic load capacity (C), the set can handle significant loads when both linear bushings are under equal load. The static load rating (C0) and dynamic torsional moment load capacity (Mt) further define its robustness for various applications. Additionally, it can operate within a permissible ambient temperature range of -20°C to 80°C, withstand maximum accelerations (amax), and achieve maximum permissible linear speeds (vmax). The LINEAR-SET LSHDR2T-50-WV-900 has a mass of 3.8 kg/m, making it suitable for systems where weight considerations are essential. Its size L dimension provides additional details on fitment requirements for integration into existing or new systems. Overall, this Bosch Rexroth linear motion set is ideal for users seeking a durable, precise, and maintenance-friendly solution in their mechanical setups where smooth linear motion is critical.

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.
