The Bosch Rexroth LINEAR-SET LSHDR2T-30-WV-900 (R072253085) is a high-performance linear motion set designed for precision applications requiring robust linear guidance and torque transmission. This product comprises two torque-resistant compact linear bushings housed in a standard compact steel sleeve, specifically tailored for use with shaft diameters of 30 mm and above. The linear set features one ball guide groove for smaller diameter shafts and two grooves for larger ones, ensuring optimal guidance and stability. With a keyway incorporated for effective torque transmission, the hardened steel bearing plates of the LSHDR2T-30-WV-900 are pre-set to zero clearance at the factory, providing immediate high precision and stability against cocking loads without the need for on-site adjustments. This set is engineered without external seals to fit applications where such protection is not required, enhancing its versatility in different environments. The dynamic load capacity C denotes the minimal value since the direction of loading may vary; however, this capacity ensures that both linear bushings share an equal load during operation. The static load rating C0 and dynamic torsional moment load capacity Mt confirm its ability to handle both static and dynamic stresses efficiently. Additionally, this linear set allows for re-lubrication, extending its operational lifespan through proper maintenance. It operates effectively within a permissible ambient temperature range of -10°C to +100°C, with a maximum acceleration of amax and a maximum permissible linear speed vmax. The weight of 1.09 kg/m indicates its lightweight yet durable construction. Overall, the Bosch Rexroth LINEAR-SET LSHDR2T-30-WV-900 is designed for seamless integration into various mechanical systems requiring precise linear movement with reliable torque-transmitting capabilities. Its robust design ensures long-term performance in demanding applications while maintaining ease of maintenance through its relubricatable features.

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.
