OverviewPU-coated SR rollers combine a metal core (steel or aluminium) with a polyurethane (PU) elastomer surface that provides high abrasion and chemical resistance, low friction and vibration damping. Designed for conveyor and material-handling systems, these rollers protect delicate or high-value products while ensuring consistent performance across variable operating conditions.
Key product informationMotor type: Brushless motor
Roller diameter: 70 mm
Input voltage: DC48 ±10%
Working system: S1/S2
Speed range: 300–1050 rpm
Cooling method: self-cooling
Features- Exceptional wear resistance: PU offers lower wear than standard rubber or plastic coatings, increasing service life under high load and speed.
- Chemical and oil resistance: Formulation resists oils, greases and many solvents to protect the core and coating integrity.
- Customizable hardness: Available in Shore 30A–95A to match gentle handling or heavy-duty transport.
- Temperature stability: Maintains elasticity and performance from -20°C to +80°C.
- Precise tolerances: Diameter tolerance typically ±0.05 mm for smooth rotation and minimal vibration.
Applications- Packaging and conveyor systems: smooth transport of boxes, cartons and wrapped products; reduces surface damage.
- Printing and paper: uniform ink contact and solvent-resistant for cleaning processes.
- Textile processing: gentle handling to avoid snags and maintain tension control.
- Automotive production: transport of painted components, door panels and dashboards with oil resistance and shock absorption.
- Electronics and semiconductors: low-outgassing and antistatic options for PCBs, LCDs and delicate components.
FAQ- Q: How should PU-coated rollers be cleaned and maintained? A: Clean regularly with mild detergent and a soft cloth; avoid harsh chemicals and abrasives. Check alignment and inspect for wear.
- Q: Can these rollers be used in wet environments? A: Yes — PU is highly resistant to water and moisture, suitable for applications with liquid exposure.
- Q: What is the lead time for custom sizes? A: Lead time depends on order complexity; typically 2–4 weeks after design approval.
- Q: Are antistatic or conductive PU options available? A: Yes — antistatic/anticonductive formulations are available for ESD-sensitive processes.
- Q: Can the PU coating be repaired? A: Minor surface damage can sometimes be repaired by sanding and applying a compatible PU topcoat; severe damage may require recoating or replacement.
