Long-term 360° rotation of cranes, mining equipment and large rotary worktables often leads to tangled, broken cables and unexpected shutdowns. YUMO SR60X120X138-5 hollow collector ring is customized for heavy-load high-power machinery. Manufactured with heavy industrial standards, it delivers stable high-current transmission 24/7 and fundamentally solves cable twisting problems.

The integrated high-temperature resistant blue bakelite base features strong impact resistance, anti-aging and high insulation, avoiding cracking and electric leakage under dusty and hot conditions. Five separated thick brass rings with independent insulation barriers eliminate crosstalk between power and control circuits. Made of solid thick brass with CNC turning and mirror polishing, the rings provide large conductive area, low heat loss and excellent anti-oxidation capacity for long-term stable conduction.

Thick split steel brush holders with precisely calibrated spring pressure are matched with high-density wear-resistant carbon brushes, which keep full contact with brass rings. Minimal resistance fluctuation and tiny sparks during rotation prevent instant power failure. Slow and even brush wear extends maintenance intervals, cutting factory downtime and maintenance expenses.

The central hollow bore allows direct shaft mounting without extra brackets for easy installation and overhaul. Heavy-duty terminal bolts with flat and spring washers firmly lock cables to avoid loose connections and overheating under continuous vibration. Dust and splash-proof housing adapts to oily workshops, open mines and construction sites.

This 5-circuit heavy slip ring supports simultaneous high-power transmission and unlimited 360° rotation without cable damage. With stable performance, fast delivery and cost advantages, it is an ideal substitute for imported heavy slip rings. Widely applied in crane turntables, mining machinery, CNC rotary tooling, rotary injection molds, construction vehicle platforms and port rotary loading equipment, it serves as a core power transmission component for all heavy rotary automation machines
