Bosch Rexroth BT300VE300 Servo Rack

Bosch Rexroth BT300VE300 Servo Rack is the BT300 card rack variant used in Rexroth Indramat Tightening Systems 300 to house and interconnect tightening electronics. This rack carries part number 0 608 830 158 and is designed for three‑phase power input (3 x 230 V); an example rack SN is 689000021, confirming it is a hardware enclosure rather than a standalone drive. The BT300 rack serves as the mounting and communication hub for KE310 units that connect the host controller to the system’s servo modules, typically LTS/LTE servo amplifiers used to drive tightening spindles. In Rexroth’s SB System Box Units family, BT300 racks are paired with compact system boxes to support one or more tightening channels; SB301 supports a single channel while SB305 can support up to five channels, making the BT300VE300 a versatile building block for scalable tightening configurations. The VE300 suffix identifies this specific BT300 rack variant and is commonly encountered in spare-part catalogs and used-for-repair listings; it represents the modular card rack that consolidates power, control, and communication electronics for Rexroth Tightening System 300 installations.
