The Bosch Rexroth Indramat BTA20.3-NA-BF-VB-BS from the BTA20 Machine Control Boards series is a precision-engineered ball transfer unit designed for industrial automation. This Type BTA device features a Main Ball Diameter of 20.3 mm constructed from Carbon Steel for high load capacity and durability. The nickel-plated steel body has a Finish of nickel-plated and a Flange Thickness of 2.5 mm, ensuring robust performance in demanding environments. Mounting is simplified with a Flange Mount design incorporating Bolt Hole Centers of 41 mm and Bolt Hole Diameter of 5.5 mm for secure installation.
The unit’s compact profile is defined by a Housing Diameter of 34 mm and an Overall Height of 22.6 mm, optimizing cabinet space without sacrificing strength. A Debris-resisting Felt Seal (BS) protects internal components from contamination, while a working range of -30°C to +70°C ensures reliable operation across temperature extremes. Integration into control architectures is seamless via native INTERBUS-S / BT-BUS Communication Bus support, enabling high-speed data exchange. The Configuration NA-BF-VB and Design 3 attributes further streamline system compatibility and simplify spare-part identification.
Engineered for longevity, the BTA20.3-NA-BF-VB-BS balances minimal maintenance with maximum uptime. Its corrosion-resistant nickel plating and precision steel balls deliver consistent performance under load. This Bosch Rexroth Indramat control board is the optimal choice for industrial assemblies requiring reliable material handling and transfer operations.
