Original Nabtesco RV Reducer RV-E/RV-C/RV-N Series for Heavy-Duty Robotic Joints
Original Nabtesco RV Reducer RV-E/RV-C/RV-N Series for Heavy-Duty Robotic Joints

Nabtesco is the undisputed global leader in precision cycloidal speed reducers, with over 10 million units shipped worldwide. The RV-E (Standard), RV-C (Hollow Shaft), and RV-N (Compact) series are the industry benchmarks for heavy-duty industrial robots, CNC machines, and medical positioning equipment. Featuring a unique two-stage reduction structure, these reducers offer exceptional impact resistance, high torsional rigidity, and extremely low lost motion, maintaining micrometer-level positioning accuracy even under extreme heavy-load conditions.

Product Highlights
  1. Extreme Rigidity & Torsional Strength: The cycloidal design distributes force across multiple contact points, ensuring minimal deformation under high loads.
  2. Ultra-Low Lost Motion: The entire series maintains lost motion within 1 arc-min, ensuring absolute precision and repeatable stopping positions.
  3. Massive Load Capacity: Integrated large-diameter angular contact ball bearings support massive external moments and axial loads directly without additional support.
  4. Superior Impact Resistance: Capable of handling instantaneous torque up to 5 times the rated value, ideal for emergency stops and high-inertia robotic movements.
  5. Compact & Proven Durability: Backed by over 30 years of field performance, the compact design ensures a design life exceeding 10,000 hours.
  6. Versatile Configurations: Available in various formats, including large hollow shafts for cable management and ultra-slim profiles for space-sensitive applications.

Frequently Asked Questions
Q: How do you guarantee the authenticity of Nabtesco reducers?
A: We source directly through authorized Nabtesco distributors. Each unit features a unique barcode and serial number for verification via the official website or local branches.
Q: What is the main difference between RV-E and RV-C series?
A: RV-E is a solid shaft unit, while RV-C features a large hollow shaft, allowing laser beams, cables, or air hoses to pass through the center for simplified design.
Q: Do these reducers require manual lubrication?
A: Most units are shipped without lubricant. We strongly recommend filling with the specified VIGO GREASE RE0 after installation as per the official manual.
Q: What are the installation requirements for precision?
A: Requirements are very high. Flatness and perpendicularity of the mounting surface directly affect service life. Detailed installation guides are provided.
Q: Can you provide matching motor flanges?
A: Yes, we offer customized motor flanges and input gears compatible with major brands like Fanuc, Yaskawa, Siemens, and more.
Q: What is the expected service life of an RV reducer?
A: Under standard rated conditions, the L10 design life is typically 6,000 to 10,000 hours. Proper lubrication can significantly extend this duration.
