The Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-2000 (R072252088) is a high-quality linear motion system designed for precision applications. This linear set is composed of steel with a compact sleeve design and is part of the DRTWV series, built to accommodate shaft diameters ranging from 20mm and above. The system includes two torque-resistant compact linear bushings and one or two ball guide grooves depending on the shaft diameter, ensuring smooth and accurate movement. The LINEAR-SET LSHDR2T-20-WV-2000 is engineered without seals for applications where they are not required, contributing to its streamlined profile. It features keyways for effective torque transmission and hardened steel bearing plates preset to zero clearance by the manufacturer, which provides stability against cocking loads. Additionally, this model offers the convenience of external seals and relubrication capability, enhancing its longevity and performance in various operational environments. With a static load rating (C0) of significant capacity and dynamic load capacity (C), the product can handle both static and dynamic loads effectively when both linear bushings are under equal load. It can operate within an ambient temperature range of -10°C to +100°C, ensuring reliability across different working conditions. The maximum permissible linear speed (vmax) is optimized for high-performance applications, while the mass of the unit is 1.7 kg/m, making it relatively lightweight given its robust construction. Overall, the Bosch Rexroth LINEAR-SET LSHDR2T-20-WV-2000 offers a combination of precision, durability, and versatility for various industrial applications requiring reliable linear motion control. Its design ensures that it can withstand substantial torsional moment loads while maintaining stability and accuracy over time.

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 .

Life expectancy calculation

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. technical illustration-R072252088-Linear set (steel), DRT2-20-WV-2000, without seal
