Entry Rolls
Custom-Engineered Polyurethane Rollers Built for Durability, Precision, and Chemical Resistance
Urethane entry Rolls
Universal Urethane specializes in designing and manufacturing urethane entry rolls. These rollers deliver exceptional durability, abrasion resistance, and precise material handling across diverse industrial applications. Our rollers provide superior grip, vibration dampening, and chemical resilience. This ensures reliable operation even under continuous use and demanding conditions.
Core Construction
The core is the structural foundation of each urethane entry roll. It is engineered for strength and dimensional stability to maintain accurate alignment and withstand operational stresses.
- Materials: High-strength steel offers rigidity. Stainless steel provides corrosion resistance, and aluminum is available when reduced mass is essential.
- Design: Core dimensions and wall thickness are optimized to minimize deflection. This preserves consistent roll geometry throughout service.
- Precision Machining: Critical surfaces, such as journal seats, are machined to tight tolerances. This ensures seamless integration with bearings and shafts.
- Durability: Cores are built to withstand multiple strip-and-recoat cycles. This maximizes lifespan and minimizes replacement costs.
Urethane Covering
Hardness and Traction Control
Our urethane covers form the critical interface of entry rolls. They are engineered to balance grip, hardness, and chemical resistance customized to your process needs.
- Hardness Range: Covers range from 20 Shore A, which is soft and provides high grip, up to 70 Shore D, which is hard and wear-resistant. We tailor these to your specific application.
- Thickness Options: Cover thicknesses vary from 0.25" to over 6.0". They are designed to absorb deflection and resist wear through extended use.
- Material Performance: Our urethane outperforms rubber by up to 4 times and mild steel by up to 10 times in abrasion and tear resistance. This is especially true under harsh conditions.
- Chemical & Thermal Resistance: Our materials resist oils, solvents, and cleaning agents. They perform within a standard temperature range of –30°C to 100°C, with specialty compounds available for higher temperatures.
- Surface Finishes: Smooth or textured finishes prevent product marking. They also maintain consistent feed and traction.
- Bonding Process: We ensure permanent urethane-to-core bonding through advanced grit blasting, primer application, and heat-cured casting.
Refurbishing & Recovery Services
Extend the life of your existing urethane entry rolls with our comprehensive refurbishing solutions. Our expert refurbishment process restores worn rollers to like-new condition, delivering cost-effective performance and minimizing downtime.
- Core Stripping & Recoating: We remove old urethane coatings and apply premium new ones. These can match or exceed your original specifications.
- Dimensional & Structural Inspection: Every roller undergoes thorough inspection before and after refurbishment. This verifies core integrity and dimensional accuracy.
- Material Upgrades: You can upgrade urethane formulations during recoating. This improves wear resistance, grip, or chemical tolerance.
- Rapid Turnaround: We offer emergency refurbishing services. This helps keep your operations running smoothly with minimal disruption.
- Traceability & Documentation: We maintain complete service records and material traceability. This supports quality assurance and simplifies reordering.
Application-Specific Performance
Urethane entry rolls are crafted to meet the exacting demands of material entry points. Control, surface integrity, and longevity are critical in these areas.
- Elastic Memory: Our rolls exhibit exceptional resilience. They maintain shape and function through continuous compression and flex cycles.
- Non-Marking: They are engineered to protect sensitive surfaces such as paper, metal, and packaging films during transfer.
- Vibration Dampening: Our rollers combine high load capacity with noise reduction. This enhances workplace safety and product quality.
- Wide Operating Conditions: They provide reliable performance across diverse environments. This includes humid and washdown settings.
Load, Speed & Environmental Ratings
- Load Capacity: Our rollers are designed to handle high static and dynamic loads common in industrial entry points.
- Speed Ratings: They are suitable for continuous operation at varying line speeds. Strong urethane-to-core adhesion ensures durability.
- Chemical Resistance: The materials protect against oils, solvents, and other common industrial contaminants.
- Thermal Performance: Standard resistance ranges from –30°C to 100°C. Specialty grades are available for more extreme environments.
- Moisture & Static Control: We use hydrolysis-resistant compounds for wet environments. Anti-static and conductive urethane options are also available for sensitive processes.
Proven Applications
- Our rollers are widely used in industrial conveyor and entry line systems.
- They are integral to metal sheet feeding and forming equipment.
- Printing and packaging machinery depend on our durable rollers.
- They are trusted in food and pharmaceutical production lines.
- Automotive and electronics manufacturing processes benefit from our solutions.
