The Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-500 (R072252080) is a high-quality linear set designed for precise linear motion applications. This product includes two torque-resistant compact linear bushings in a standard compact steel sleeve, which are capable of accommodating shaft diameters of 20mm. The set is equipped with ball guide grooves, ensuring smooth and accurate movement along the shaft, which is included in the standard length as specified by Bosch Rexroth. This LINEAR-SET is characterized by its robust design without external seals, making it suitable for environments where less contamination is present. The tandem arrangement of the bushings allows for a high load capacity when both linear bushings are under equal load, ensuring minimal values even when the direction of loading cannot always be clearly defined. The unit boasts an impressive dynamic load capacity (C), static load rating (C0), and dynamic torsional moment load capacity (Mt), providing reliable performance under varying loads. Furthermore, it has been engineered with torquetransmitting, hardened steel bearing plates that are set to zero clearance by the factory to maximize precision and stability against cocking loads. For maintenance purposes, this LINEAR-SET is relubricatable, extending its service life and maintaining its efficiency over time. It operates effectively within a permissible ambient temperature range of -30°C to +80°C and can handle maximum accelerations and linear speeds without compromising performance. With a weight of 0.9 kg/m, this linear guide system offers a balance between durability and ease of handling. The size L specification further defines its dimensions for proper integration into various applications. Overall, the Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-500 provides a reliable solution for those requiring precise linear motion control in their mechanical systems or machinery.

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.
