The Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-1200 (R072252087) is a comprehensive linear motion set designed for precision and robustness in various applications. This linear set is crafted from steel and includes a compact LB sleeve version with tandem ball guide grooves, specifically engineered to provide smooth, accurate linear movement. The set comes with a standard length shaft of 20 mm diameter that is included in the package, ensuring compatibility and ease of installation. This model boasts two torque-resistant compact linear bushings and is suitable for use with one ball guide groove for diameter shafts up to 20 mm and two ball guide grooves for larger diameter shafts. It features a keyway for effective torque transmission, enhancing its performance in applications that require precise motion control. The hardened steel bearing plates are pre-set to zero clearance by the manufacturer, offering optimal stability against cocking loads and ensuring high precision throughout its operation. Additionally, the LINEAR-SET LSHDR2T-20-WV-1200 is designed without external seals, making it relubricatable which extends the product's life span by allowing maintenance to be performed as needed. This product operates efficiently within a permissible ambient temperature range from -10°C to +80°C and can handle maximum accelerations as well as high linear speeds without compromising its dynamic load capacity or static load rating. The unit's mass is 1.8 kg/m, contributing to its sturdy yet manageable design. With a size L specification and significant dynamic torsional moment load capacity (Mt), this linear guide type—which falls under the Linear bushing and shaft series—is ideal for various industrial applications where reliability and precision are paramount. The Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-1200 is indeed an exceptional choice for those seeking top-tier motion control solutions.

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 .

Installation

The Linear Sets come preassembled and set to zero clearance. When pulling out the shaft, the adjusting screws must be loosened and the torque-resistant Linear Bushing reset.

Installation Linear sets with torque-resistant compact linear bushings

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.
