BTA20.4-NA-DB-VB-BS
BTA20 Machine Control Boards
The Bosch Rexroth Indramat BTA20.4-NA-DB-VB-BS from the BTA20 Machine Control Boards series is a precision-engineered Type Bearing Unit with Design 4 architecture. Constructed from robust Steel, this unit features a 20 mm bore diameter to accommodate medium-duty shafts with excellent alignment. It delivers a dynamic load rating of 22,000 N and a static load rating of 14,000 N, ensuring long service life under cyclic and shock loading. The combination of strength and precision makes this board-mounted bearing ideal for harsh industrial automation environments.
Designed for secure installation, the BTA20.4-NA-DB-VB-BS employs an NA (Narrow Angle) housing type and a DB (Double Set Screw) locking mechanism to eliminate axial play and simplify mounting. A VB dual lip seal with slinger protects internal surfaces from contaminants while preserving lubrication, and the IP65 front panel protection class safeguards electronics from dust and water ingress. The unit supports the INTERBUS-S / BT-BUS communication bus with a configurable baud rate of 0 to 38400 bps for seamless integration into distributed control systems. Rated for an operating temperature range of -20°C to +120°C, the bearing unit maintains consistent performance across extreme thermal conditions.
Installation and maintenance are streamlined thanks to a set screw mounting method and a standardized mounting dimension of 375 x 137 x 119 mm that matches existing panel cutouts. With a rated power consumption of 18W and output current capability of up to 200 mA per channel at 24V DC, the module handles auxiliary electronics without external power supplies. Its combination of high load capacity, compact footprint, and robust sealing makes the BTA20.4-NA-DB-VB-BS an indispensable component for precision positioning, conveyor systems, and automated assembly lines in demanding industrial settings.
