BTA20.3-BA-NN-BA-NN

The Bosch Rexroth Indramat BTA20.3-BA-NN-BA-NN control board is a precision-engineered member of the BTA20 Machine Control Boards series designed to deliver high-accuracy positioning and load handling in industrial automation. Featuring a bore size of 20 mm paired with a shaft diameter of 20 mm, this module accommodates linear motion systems requiring tight alignment without drift. The open steel housing ensures structural rigidity under load while simplifying visual inspection and maintenance. With a permissible load of 1,500 N, the unit supports demanding stress conditions, making it suitable for high-performance control rigs. Its lightweight design and flange mounting enable rapid installation in various machine architectures.

The board's mechanical subsystem incorporates a ball bushing bearing mechanism with 4 ball circuits that reduce friction and wear, extending service intervals and preserving guide smoothness. Constructed from durable steel, the assembly maintains high guide accuracy across its operational range. The flange mounting type secures the module firmly to standard automation frames, while the absence of sealing (without seal) streamlines internal access and reduces complexity. An operating temperature bracket of -20°C to 80°C ensures consistent material tolerances in non-climate-controlled environments. This configuration (Design 3, Configuration BA-NN-BA) omits communication bus interfaces to focus on mechanical precision and simplicity.

Performance metrics emphasize repeatability and responsiveness: the assembly's outer diameter of 32 mm and overall length of 80 mm deliver a compact footprint that integrates cleanly into multi-axis systems. The open housing type balances protection with ease of access, enabling quick inspections without disassembly. Backlash is minimized through precise ball circuit clearances, while the steel material resists deformation under cyclical loads. The unit's static stiffness supports rapid acceleration and deceleration profiles, preserving positional accuracy under dynamic conditions. In environments where lubrication control and particle ingress are managed externally, the absence of internal seals accelerates maintenance cycles and lowers total cost of ownership.

Integration into machine tools, linear actuators, and control rigs is streamlined by the board's standardized flange dimensions and mounting pattern. The BTA20.3-BA-NN-BA-NN excels in axis systems that demand repeatable motion over fixed paths, including pick-and-place setups, inspection gantries, and precision assembly lines. Without onboard communication buses, the unit interfaces directly with external drives and controllers, reducing wiring complexity. Its combination of high load capacity, compact geometry, and robust bearing design make it a core component for industrial automation applications requiring reliable, high-precision motion control.
