25mm Through Hole 1 Circuit 750A High Current Slip Ring H62 Copper Rotor Precious Metal Contact for Welding Robot Rotary Power Supply
1.Product Overview
This through-hole high-power slip ring is a dedicated rotary power transmission component for automated welding equipment. The standard inner bore size is 25mm, single circuit supports 750A ultra-large current load, which can continuously transmit main welding power during 360° unlimited rotation of welding robotic arms, completely avoid cable twisting, winding and fracture failure caused by frequent reciprocating rotation of robot joints.
The rotor is made of high-conductivity H62 brass with excellent heat dissipation, matching insulated engineering plastic stator and high-performance precious metal contact pairs. The contact resistance fluctuation is strictly controlled below 10mΩ, effectively stabilizing welding current and eliminating unstable welding arc, cold solder and other defective products caused by poor contact. With IP51 protection grade and wide temperature & humidity adaptability, it can work stably in common welding workshop environments, and all structural sizes can be customized according to robot installation space requirements.
2.Core Product Advantages
- 1.750A Super High Current Bearing CapacitySingle channel supports 750A heavy load, compatible with AC and DC welding power supplies, fully meets the high-power power supply demand of heavy industrial welding robots, stable output prevents arc fluctuation during long-term welding production.
- 2.Precious Metal Low Resistance Contact System Precious metal contact pairs have outstanding anti-spark, anti-oxidation and anti-ablation performance. Even after millions of robot rotation cycles, the resistance change is extremely small, effectively reducing sudden power failure and welding rejects caused by poor contact.
- 3.H62 Copper Rotor with Excellent Heat DissipationH62 brass rotor features high electrical conductivity and thermal conductivity, quickly dissipate heat generated by long-time 750A high-current operation, avoid component overheating and burnout, extend service life of slip ring.
- 4.Insulated Engineering Plastic Stator, Adapted to Welding Workshop High-strength engineering plastic stator provides reliable insulation, lightweight structure reduces robot load, and resists corrosion of welding smoke and metal dust in workshop.
- 5.Strong Environmental Adaptability & IP51 ProtectionOperates normally under -30℃ low temperature to +80℃ high temperature, humidity below 70%RH. IP51 structure blocks workshop fine dust and vertical water splashes, suitable for most standard welding production lines.
- 6.25mm Through-hole Design & Full Customization Support25mm central bore reserves space for robot internal wiring and pipeline layout; we support custom lead length, wire outlet direction, flange mounting holes and higher protection level for heavy dust welding workshops.
4. Main Application Scenarios
- Multi-axis automatic welding robot arm rotary main power transmission
