RS-50A

Product catalog summary
Overview: The document introduces the RS-50A and RS-50B models, part of the RS series, designed for index tables. The RS-50A is noted for its high-speed rotation and a maximum allowable load of 1,500 kg.
Specifications: The RS-50A/B models feature a precision reduction gear RV™, known for high accuracy, rigidity, and reliability. They offer high-speed indexing (180° in 0.7 seconds with a 10 kgm² moment of inertia) and a compact design that reduces the machine's total height. The models include a φ50 mm hollow shaft for wiring and are compatible with major servo motors. They are pre-lubricated with RV GREASE LB00 and have easy oil change ports on all faces.
Technical Details: The RS-50A/B models have a maximum allowable load of 1,500 kg, a rated torque of 490 Nm, and a momentary maximum allowable torque of 2,450 Nm. The rated output speed is 15 rpm, with an allowable output speed of 60 rpm. Positioning accuracy is 60 arc.sec. with repeatability of ±5 arc.sec. The models support reduction ratios of 65.4, 130.8, and 163.5, with an endless operation range.
Design Features: The RS-50A includes an output flange, while the RS-50B does not, allowing selection based on customer equipment. The height from the base to the output flange is 136 mm for RS-50B and 158 mm for RS-50A. The models weigh 40 kg, excluding the motor flange and input spline.
Application and Usage: The gearhead is suitable for applications requiring both load force and moment load, provided it is used within the allowable moment range. The document includes diagrams for allowable moment and center of gravity height and load.
Contact Information: The document provides contact details for Nabtesco offices in Europe, North America, India, and Japan for further inquiries and support.
