BTA20.3-NA-HP-VB-BS
BTA20 Machine Control Boards
The BTA20.3-NA-HP-VB-BS, Bosch Rexroth Indramat, BTA20 Machine Control Boards hydraulic bolt tensioner features a robust Type designation within the BTA20 family. Engineered for industrial automation, it delivers precise preload control by converting hydraulic pressure into tensile force. The unit's compact footprint stems from its single PCB architecture, minimizing internal complexity while supporting high-performance operation. Designed for rigorous use, this tensioner integrates seamlessly into automated bolting systems, ensuring consistent torque application and minimizing cycle times.
With a Maximum Bolt Diameter of M20 and a Stroke Length of 10 mm, the BTA20.3-NA-HP-VB-BS handles bolts up to grade 10.9 safely. It sustains a Maximum Working Pressure of 1500 bar to generate a Maximum Load Capacity of 200 kN, while its Single Acting, Spring Return Operation and Safety Factor of 2.0:1 guard against overload conditions. Constructed from High Strength Alloy Steel with a Nickel Plated Finish, the assembly resists wear and corrosion in harsh environments. Sealing is assured by Viton components rated for a Temperature Range from -20 °C to +200 °C, and quick setup is enabled via a Quick Connect Coupling. Communication and control integrate over the native INTERBUS-S / BT-BUS interface for real-time monitoring and coordination.
The BTA20.3-NA-HP-VB-BS excels in reliability and uptime, thanks to its rugged construction and simplified maintenance. Its compact design and standardized communication bus facilitate rapid integration into existing control architectures without reengineering. Ideal for demanding assembly lines, pressure vessels, or heavy-duty equipment, this tensioner delivers precise, repeatable bolting cycles while reducing operator intervention and production downtime.
