18 Circuit Through Bore Mini Slip Ring 1A High Current Hollow Shaft Rotary Connector

Engineered for high-speed rotating platforms, the SP013018 slip ring delivers reliable electrical performance at 0-10,000 rpm with a service life of 10 million revolutions. Featuring 304 stainless steel housing, 0.5N*cm low starting torque, and operation from -50°C to +80°C, it performs reliably in harsh industrial environments.

Used for high-speed testing platform strain gauge signals, thermocouple signals, and similar applications, including aircraft engine testing, high-speed rail component testing, and automotive wheel hub performance testing.

• Friction Pair Technology: Gold metal contact technology ensures ultra-long service life
• Integrated Casting Process: Guarantees concentricity between ring groove and bearing ≤ 0.01mm
• Mirror Processing Technology: Achieves slip ring contact surface smoothness of Ra0.02 for more reliable contact
• Precision Component Manufacturing: Dimensional tolerance <0.01mm, axial displacement <0.01mm for high precision and stable performance
• Advanced Brush Wire Modulation: Near-zero pressure brush design extends slip ring life by 1/3
• High Speed Capability: Maximum speed of 8,000 rpm (with cooling system)
• Extended Lifespan: Maximum operational life of up to 100 million revolutions
