Wringer Rolls
Urethane Wringer Rolls
Universal Urethane manufactures urethane wringer rolls engineered to remove excess liquids, oils, or contaminants from strip and sheet surfaces in coil processing and finishing lines. Designed for high-pressure nip applications, our urethane-covered wringer rolls provide consistent squeezing action, controlled traction, and non-marring contact for superior strip cleanliness and surface protection.
Core Construction
The effectiveness of a wringer roll begins with its core, which must withstand high nip pressures while maintaining concentricity and balance.
- Core Materials: Steel, stainless steel, or aluminum in solid or tubing construction.
- Precision Machining: Journals and bearing seats produced or restored to print for accurate fit and load-bearing capability.
- Inspection & Testing: UT and Wet MAG inspection available for shafts and weldments, with reports provided.
- Journal & Shaft Services: Shaft replacement, weld repair, and press-fit operations extend core service life.
- Dynamic Balancing: Rolls balanced after machining and recovering to ensure smooth operation at line speeds.
- Complete Assemblies: Supplied fully assembled with shafts, bearings, couplings, and covers for direct installation.
Urethane Covering
The urethane covering is specifically designed for nip-pressure applications, providing durability, elasticity, and fluid resistance.
- Durometer Range: Custom polyurethane hardness, typically 85–95 Shore A, selected for controlled compression and long wear life.
- Surface Finish: Smooth ground finishes for even pressure distribution and non-marking contact.
- Grooved Options: Helix, herringbone, or spiral grooves available to improve fluid displacement and enhance drainage.
- Performance Properties: High tear strength, superior abrasion resistance, and resistance to oils, coolants, and cleaners.
- Bonding & Cure: Covers applied with grit-blasted cores, primer adhesives, and heat curing for secure adhesion under repeated nip cycles.
Performance in Coil Processing
Wringer rolls are designed to deliver consistent surface cleaning and fluid removal under demanding line conditions.
- Apply uniform nip pressure for effective fluid removal.
- Protect strip finishes with resilient, non-marring urethane contact.
- Provide stable traction in wet, oily, or chemical-exposed environments.
- Resist wear and maintain performance across repeated start/stop cycles.
Maintenance & Recovering Services
Universal Urethane extends wringer roll service life with comprehensive recovering and rebuild programs.
- Recovering: Worn coverings stripped, cores inspected and refurbished, and new urethane applied to OEM or upgraded specifications.
- Rebuild Process: Complete cleaning, NDT inspection, grinding, balancing, and finishing performed to print.
- Service Options: Standard and expedited turnaround available with pickup and delivery.
Applications
- Coil cleaning and preparation lines
- Surface treatment and coating operations
- Fluid removal in galvanizing and plating lines
