Stainless Steel Composite Guide Roller

·Composite Construction
Carbon steel core with stainless steel outer layer metallurgically bonded through explosion cladding, no delamination or separation. Solid stainless steel rollers are too heavy, creating inertia issues during high-speed start-stop; carbon steel rollers corrode from moisture and acids. This composite design reduces overall weight by 35% while maintaining high bending stiffness, delivering more stable tension at high speed.

·316L Food-Grade Surface
Resists acids, alkalis, and moisture corrosion without rust pitting. Withstands dyes, adhesive acid extracts, food processing moisture, and chemical solvents. No rust spots or oxidized debris contaminate finished products. Suitable for medical, food, and chemical clean production lines without particle shedding.

·Ultra-Mirror Polished Surface
Multi-stage mirror polishing achieves roughness Ra≤0.01μm with no burrs or surface defects. Lightweight nonwovens and ultra-thin films pass smoothly without scratches, stretching, or wave-edge defects. Suitable for high-precision optical films and lithium battery separators.

·G1.0 Dynamic Balancing 
Integral forged core with multiple stress-relief processes eliminates welded seam stress defects. Three-stage progressive balancing supports line speeds up to 280m/min with consistent concentricity, eliminating frequent tension adjustment.

·Optional Temperature Control
Built-in surrounding heat exchange channels maintain surface temperature differential ≤±1.0℃. Prevents substrate shrinkage and edge tension variation from temperature gradients, accommodating both ambient and heated operation modes.

Plastic film casting, slitting, and winding lines (CPP, PET, PLA) for scratch-free guidance; textile dyeing and nonwoven finishing for acid/alkali-resistant transport; tissue paper and papermaking for contaminant-free paper guidance meeting hygiene standards; food packaging substrate lines for food-contact compliant transport; medical cleanroom materials for nonwoven and breathable film guidance; synthetic leather traction for flat, distortion-free base fabric transport.
