As a premier belt conveyor roller manufacturer with over 10 years of expertise, DARKO specializes in producing high-performance, durable rollers for bulk material handling in mining, cement plants, logistics, and industrial production lines. Our ISO & CE-certified conveyor rollers feature precision bearings, wear-resistant coatings, and advanced sealing technology, ensuring smooth operation and extended service life under heavy-duty conditions.
With a global presence across 20+ countries, we offer customizable roller solutions in diameters ranging from 50mm to 300mm, designed for optimal load capacity, energy efficiency, and minimal maintenance.

Belt Conveyor Roller Working Principle
The belt conveyor roller operates by using the drive roller connected to a motor, which propels the conveyor belt through surface friction to achieve continuous material transportation. Carrying rollers uniformly support both the belt and material load, while return rollers guide the empty belt back to complete the circulation system.
Featuring precision bearings for low-resistance rotation, the drive roller typically has rubber coating for anti-slip performance, with specialized versions (like impact rollers) absorbing shock loads. The entire system ensures smooth belt operation through coordinated roller functions, making it suitable for various industrial applications including mining and logistics.
Advantages of Belt Conveyor Rollers
Belt Conveyor Rollers deliver reliable material handling with precision-engineered durability, customizable configurations, and proven performance across industrial applications.

Reinforced bearings and thick-walled steel tubes enable a maximum dynamic load of 5 tons per roller, ideal for heavy-duty applications.

Precision bearings combined with wear-resistant coatings increase service life by over 50% compared to standard rollers.

Optimized friction coefficient (<0.03) reduces belt drive energy consumption by 15%-20%.

Hot-dip galvanized or 304 stainless steel construction passes 2000-hour salt spray tests, suitable for humid and corrosive environments.

Sealed noise-reducing structure operates below 65 dB, perfect for indoor and noise-sensitive facilities.

IP65-rated bearing housings prevent dust and moisture ingress, significantly extending maintenance intervals.

Standardized shaft ends (DIN/ANSI compliant) with quick-release clamps allow replacement in under 15 minutes.

Tailored options available from 50-300mm diameters with various materials/coatings to meet specialized operational needs.

Core Functions and Application Value of Belt Conveyor Rollers
As the “critical joints” of conveying systems, belt conveyor rollers enable efficient material handling through three core functions: driving, load-bearing, and guidance. The drive rollers provide power (with anti-slip rubber coating), carrying rollers distribute material loads (maximum 5 tons/roller), and return rollers ensure proper tracking. Their specialized designs (including impact-resistant, corrosion-proof, and food-grade configurations) adapt to demanding applications in mining, food processing, chemical plants and other harsh environments. Delivering remarkable advantages – including tripling belt lifespan, reducing energy consumption by 20%, and cutting maintenance costs by 30% – these rollers serve as essential components for modern intelligent conveying systems.


Drive Roller
Core Function: The power source of belt conveyor systems, converting motor torque into belt traction for stable operation.
Key Features:
✔ High-Strength Lagging: Diamond/herringbone rubber coating (friction coefficient ≥0.4) prevents slippage and resists wear
✔ Multiple Drive Options: Keyway connection (high torque) or locking assembly (maintenance-free)
✔ Custom Solutions: Compatible with frequency-controlled motors, hydraulic drives, etc.
Selection Guide:
Power Matching: Calculate required torque based on belt tension and speed
Surface Treatment: Oil/heat-resistant lagging available (for mining, chemical industries)
Carrying Roller
Core Function: Supports conveyor belt and material weight, determining transport efficiency.
Key Features:
✔ Trough Design: 35°/45° 3-roll configuration increases bulk material capacity by 30%
✔ Heavy-Duty Construction: Thick-walled steel tubes (6-12mm) with precision bearings (5-ton load capacity)
✔ Low Resistance: Rotation resistance ≤1N, reducing energy consumption by 15%
Selection Guide:
Belt Width: Roller length should exceed belt width by 50-100mm
Impact Resistance: Buffer type for mining, quiet operation for logistics


Return Roller
Core Function: Guides empty belt return while preventing misalignment and sagging.
Key Features:
✔ V-Guide Tracking: Auto-corrects belt deviation (±5° adjustment)
✔ Self-Cleaning Option: Spiral design removes belt debris
✔ Sealed Protection: IP65-rated bearings for wet/dusty environments
Selection Guide:
Installation Spacing: Typically 1.5x carrying roller intervals
Special Requirements: Stainless steel for food grade, dust covers for mining
