The Bosch Rexroth LINEAR-SET LSSDR2T-25-WV-500 (R109752580) is a precision-engineered linear motion set designed to provide high rigidity and load-bearing capacity in a compact form factor. This set includes a precision steel shaft with a diameter of 25 mm, featuring two ball guide grooves for smooth and precise linear movements. The shaft comes in a standard length as per the manufacturer's table, ensuring compatibility with various applications. Equipped with two torque-resistant linear bushings, the LINEAR-SET offers excellent stability against cocking loads, making it suitable for scenarios where precise alignment is critical. These bushings are pre-adjusted to zero clearance by the manufacturer to ensure optimal performance right out of the box. The tandem arrangement of the bushings distributes loads evenly, enhancing the dynamic and static load capacities of the system. The included bearing plates are made from hardened steel, contributing to the set's ability to transmit torques effectively while maintaining accuracy. Although this model comes without external seals, it boasts an impressive resistance to environmental factors within its permissible ambient temperature range. Bosch Rexroth has designed this linear set for easy integration into various applications requiring high precision and torsional rigidity. The product's dynamic load capacity and maximum permissible linear speed are indicative of its suitability for high-performance tasks. Additionally, its mass is optimized to provide substantial support without excessive weight. Overall, the Bosch Rexroth LINEAR-SET LSSDR2T-25-WV-500 is a robust solution for those seeking reliable linear motion components that can withstand significant loads while maintaining precise movement control in industrial settings.

1) Load rating when both Linear Bushings are under equal load. The load ratings indicated are minimal values as the load direction cannot always be clearly defined.
The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the  values in the table need to be multiplied by 1.26.

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.

General mounting instructions

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-R109752580-Linear set (steel), DRT2-25-WV-500, without seal
