The Bosch Rexroth LINEAR-SET LSSDR1-12-WV-900 (R109621285) is a comprehensive linear motion set designed for precision applications that require high levels of torque resistance and stability against cocking loads. This product features a precision steel shaft with one ball guide groove and a torqueresistant linear bushing, which together provide smooth and accurate linear motion. The steel bearing plates are hardened and set to zero clearance ex works to ensure precise movement without play. This LINEAR-SET is notable for its robust construction without external seals, making it suitable for environments where such seals are not necessary. The standard steel precision housing is built to withstand dynamic load capacities, with the minimum values provided to account for varying loading directions. It can operate within an ambient temperature range of -...°C to ...°C, ensuring reliability across different working conditions. The product's outer diameter and size specifications correspond with the Rexroth standard, guaranteeing compatibility with a wide range of applications. The maximum permissible linear speed (vmax) and acceleration (amax) are indicative of the set's capability to handle high-speed operations efficiently. With a static load rating C and a dynamic torsional moment load capacity Mt, this LINEAR-SET is engineered for demanding tasks where both static and dynamic forces are present. Its weight specification ensures that it contributes minimally to the overall mass of the machinery it is integrated into, thus not compromising on system efficiency. In summary, the Bosch Rexroth LINEAR-SET LSSDR1-12-WV-900 (R109621285) is an advanced solution for linear motion requirements in various applications that demand precision, durability, and resistance to torsion and cocking loads. Its design reflects an understanding of the challenges faced in dynamic environments where performance and reliability are paramount.

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-R109621285-Linear set (steel), DR1-12-WV-900, without seal
