NO-CRUSH WHEELS
- Polyurethane rollers for corrugated board
- Transport and guide boards safely
- Minimal compression to protect flutes
- Maintain grip and board integrity
No-Crush Wheels are specialized polyurethane rollers used in corrugators, inliners, and other converting equipment to transport, guide, or hold down corrugated board without damaging the flutes.
They are designed to apply minimal compression while maintaining grip, ensuring the board’s structural integrity and preventing flute deformation during feeding, guiding, or spacing operations.
Construction Features
Material
High-Speed Steel (HSS) & Tungsten Carbide-Tipped (TCT) & Solid Carbide
Durometer Options
Straight edge for clean shearing. Multiple hardness levels (e.g., 40–70 Shore A) color-coded for quick identification.
Core/Hub
Aluminum, steel, or composite hubs for mounting stability.
Profile
Spoked or solid designs to reduce weight and allow controlled deflection.
Mounting Options
Hub-mounted, shaft-mounted, bonded hub, or snap-in bearing styles.
Heat & Moisture Resistance
Formulated to withstand corrugator wet-end conditions without degrading.
Deflection Control
Engineered to compress just enough for grip without crushing flutes.
Key Selection Factors
When choosing no-crush wheels:
- Application – Hold-down, guiding, feeding, or spacing.
- Durometer (Hardness) – Softer for delicate boards, harder for heavier grades.
- Operating Environment – Heat, humidity, and dust levels.
- Wheel Size – Diameter and width to match machine design.
- Mounting Style – Hub type, bore size, or bearing type.
- Deflection Characteristics – Match compression to board caliper and flute type.
- Material Quality – Polyurethane formulation for wear life and flexibility.
- OEM Compatibility – Dimensions and fit for your specific machine.

Common Types
Hold-Down Wheels
Keep board in contact with belts or rollers without crushing
Guiding Wheels
Maintain sheet alignment through the machine.
Feeder Wheels
Control sheet feeding into printing or die-cutting sections.
Spacing/Metering Wheels
Control product spacing in downstream processes
Custom Profile Wheels
Designed for unique product handling needs.
Solid Carbide Knives
Premium option for maximum wear resistance.
Maintenance & Care
To maximize life and performance:
- Regular Cleaning – Remove starch, dust, and debris to prevent glazing.
- Check for Wear – Inspect for cracks, flat spots, or excessive hardening.
- Correct Mounting – Follow OEM direction/orientation guidelines.
- Avoid Overloading – Excessive pressure can deform wheels and damage board.
- Rotation – Swap positions periodically to even out wear.
- Storage – Keep spares in a cool, dry place away from direct sunlight.
