Swing Arm Rolls and Separator Rolls
Urethane Swing Arm & Separator Rolls
Universal Urethane manufactures urethane swing arm rolls and separator rolls engineered for precision strip handling in coil processing lines. Swing arm rolls provide controlled guidance and support on pivoting mechanisms, while separator rolls prevent edge-to-edge contact and maintain slit strip separation during high-speed operations. Both roll types are designed with precision-built cores and durable urethane coverings to ensure long-lasting performance, surface protection, and reduced downtime.
Core Construction
The reliability of swing arm and separator rolls begins with the strength and precision of their cores.
- Core Materials: Steel, stainless steel, or aluminum in solid or tubing construction.
- Precision Machining: Journals and bearing seats manufactured or restored to print for accurate fit and alignment.
- Inspection & Testing: UT and Wet MAG inspections available for shafts and weldments, with reports supplied.
- Journal & Shaft Services: Shaft replacements, weld repairs, and press-fit services extend the life of existing cores.
- Dynamic Balancing: Rolls balanced after machining and recovering to minimize vibration and ensure smooth operation.
- Complete Assemblies: Provided fully assembled with shafts, bearings, couplings, and covers for direct installation.
Urethane Covering
The urethane covering ensures both traction and protection, tailored to the unique demands of swing arm and separator roll applications.
- Durometer Range: Custom polyurethane hardness, typically 85–95 Shore A for resilience, wear resistance, and stability.
- Surface Finish: Smooth ground for non-marking performance; rough-ground finishes available for oily or wet environments.
- Grooved Options: Diamond, helix, herringbone, spiral, chevron, checkerboard, and crepe profiles for improved grip and fluid shedding.
- Performance Properties: High abrasion resistance, impact absorption, and non-marring strip contact.
- Bonding & Cure: Grit-blasted cores, primer adhesives, and heat curing provide permanent adhesion and long-term reliability.
Performance in Coil Processing
Swing Arm Rolls:
- Maintain stable strip contact while accommodating swing arm pivoting.
- Provide traction without marking across variable strip conditions.
- Absorb shocks and resist wear under continuous line adjustments.
- Ensure balance and tracking through corrective movements.
Separator Rolls:
- Maintain precise separation of slit strips during slitting and recoiling.
- Protect edge integrity and coating quality.
- Operate smoothly at high line speeds without vibration.
- Deliver consistent separation and long wear life.
Maintenance & Recovering Services
Universal Urethane extends the service life of swing arm and separator rolls through comprehensive recovery services.
- Recovering: Worn coverings stripped, cores inspected and refurbished, and new urethane applied to OEM or upgraded specifications.
- Rebuild Process: Cleaning, inspection, NDT testing, grinding, balancing, and finishing performed to print.
- Service Options: Standard and expedited turnaround available with pickup and delivery.
Applications
