Idler Rollers

Specifications

• Product Category: Precision Transmission & Conveying Components
• Outer Diameter (OD) Range: Φ5 mm to Φ60 mm (Micro to medium-duty custom sizing)
• Roller Body Materials: Wear-resistant POM (Acetal), Engineering Nylon (PA66 / Glass-filled PA), ABS, or Metal Insert-Molded Composites
• Ring / Belt Materials: High-elasticity wear-resistant elastomers (NBR, EPDM, Silicone, PU Round Belts)
• Structural Types: Single/Double grooved rollers, smooth transport rollers, integrated gear/bearing seat compound rollers
• Primary Functions: Long-distance span power transmission, sheet/paper conveying, vibration damping, acoustic noise reduction
• Application Note: For precise synchronous positioning without slippage, timing belts and timing pulleys are recommended.
• Applications: Office Automation (Printers/Copiers/Scanners) Paper Feed Rollers, Miniature Conveyor Lines, Currency Discriminator Transport Shafts, Smart Home Appliances

Manufacturing Processes & Capabilities

• Precision Groove Tooling & Runout Control: Covers Φ5 mm to Φ60 mm OD ranges; micro-tolerance tooling ensures precise groove profiles, smooth surface finish, and tight roundness to prevent rubber O-ring jumping, slippage, or premature wear.
• Bore Concentricity & Insert Molding: Strictly maintains concentricity between the mounting bore and outer grooved surface; supports metal shaft insert molding or bearing pocket integration for balanced, low-friction rotation.

Features & Advantages

• Long-Span Drive & Flexible Layout: Utilizes elastomeric O-rings/round belts to span long center distances without multi-stage intermediate gear trains, simplifying mechanical packaging and reducing system weight.
• Vibration Damping & Whisper-Quiet Operation: Elastic rubber rings absorb motor vibration and operational resonance, significantly dampening acoustic decibel levels for quiet office and home environments.
• Overload Slip Protection: Inherent frictional drive mechanics allow safe belt slippage during mechanical jams or stalls, protecting drive motors and gears from overload damage.
