Guide Rollers

Silicone-covered guide and drive rollers with ground surfaces for web handling and printing.

Application Overview

Web-handling rollers need a cover that grips consistently without marking the product. We vulcanize silicone covers onto customer cores or supply complete rollers, then grind to final diameter and runout spec. Durometer from 20 to 80 Shore A covers release to high-traction duty; food-grade compounds available for packaging lines.

Technical Standards

  • ✓Diameter tolerance ±0.02 mm and runout ≤0.02 mm after grinding (typical)
  • ✓Durometer 20-80 Shore A per application; ASTM D2240 verified
  • ✓FDA / LFGB food-grade compounds for food packaging lines
  • ✓Dynamic balance available for high-speed duty

Manufacturing Process

Covers are extruded-wound or molded onto prepared cores, autoclave vulcanized, then CNC ground.

  • Core preparation: degrease, grit-blast, prime for permanent bond
  • Grinding produces final OD, crown and surface finish per print
  • Texture (grooves, knurl) available for traction or release control
  • Recover service: worn covers stripped and re-covered

Quality Inspection

  • 🔍100% visual inspection (flash, short-shot, contamination) before packing
  • 🔍Dimensional verification against approved drawing; FAI report on first shipment and after any tooling change
  • 🔍Hardness per ASTM D2240 (Shore A) on every batch
  • 🔍Lot traceability: material batch, cure records and operator logged for every carton
  • 🔍OD / runout / crown profile inspection report per roller
  • 🔍Cover thickness verification at multiple stations
  • 🔍Surface finish and texture visual audit
  • 🔍Bond integrity: tap/ultrasonic sounding for voids
