Product Offerings
Roll-Ven offers a diverse range of rollers for various industrial applications, including gravity roller conveyors, belt conveyor rollers, power-driven rollers, and special rollers and accessories for curves and belt conveyors.

Technical Specifications
Rollers are designed with various shaft options, rubber components, and finishes to meet specific industrial needs. The designation code includes details such as casing diameter, number of teeth, shaft length, and control type.

Strategic Focus
The company's strategy emphasizes research, technological innovation, and dynamic customer engagement. Roll-Ven partners with leading suppliers of automated systems in Italy, ensuring optimal performance and reliability even in challenging conditions like quarries and foundries.

Applications
Roll-Ven rollers are used across diverse sectors, including mechanical transport, bottling, packaging, pharmaceuticals, and chemicals, demonstrating their adaptability and technological advancement.

Roller Specifications and Configurations
The document provides detailed specifications for ALFA and BETA rollers used in gravity and belt-driven conveyors, including dimensions, weight, materials, and customization options. ALFA rollers are available with galvanized or stainless steel shafts and tubes, while BETA rollers can have PVC or steel tubes.

Performance and Limitations
BETA rollers with PVC tubes are noted for their smooth and silent operation, resistance to corrosion, and suitability for light loads at temperatures not exceeding 50°C. Steel tube BETA rollers maintain load capacity as roller length increases but share the same temperature limitation.

Customization Options
Available customizations include different shaft configurations, material choices (galvanized or stainless steel), and coatings (PVC or rubber sheath).

Graphical Data
The document includes graphs showing the maximum load capacity (DaN) relative to roller length for different shaft diameters.

Roller Types and Applications
The document provides technical specifications for GAMMA, DELTA, and KAPPA rollers, designed for different load capacities and environments, including dusty conditions. GAMMA rollers are suitable for straight-line roller conveyors and medium load transport, DELTA rollers for heavy load transport, and KAPPA rollers focus on robustness and reliability.

Technical Specifications
Detailed dimensions and weight specifications for each roller type and configuration are provided, along with static load capacity and roller length for various models.

Conclusion
The document serves as a comprehensive guide for selecting the appropriate roller type based on specific conveyor system requirements, load capacities, and environmental conditions.

Power-Driven Rollers
The document provides technical specifications and operational guidelines for power-driven rollers, focusing on chain-driven and belt-driven roller conveyors. Chain-driven systems are suitable for heavy loads at low speeds, while belt-driven systems are preferred for light loads and high speeds.

Drive Mechanisms
Two primary drive systems are discussed: chain-driven and belt-driven. Chain-driven systems are suitable for heavy loads at low speeds, with speeds typically ranging from 0.1 to 0.5 m/s. Belt-driven systems are preferred for light loads and high speeds, offering simplicity, low noise, and cleanliness.

Operational Recommendations
For optimal performance, the motor reducer should be positioned at the downstream end of the conveyor or centrally for reversible conveyors. This ensures even tension across rollers, except for end rollers which bear more load.

Figures and Diagrams
The document includes several figures illustrating different drive configurations and roller arrangements, highlighting the positioning of motors, tensioners, and rollers.

Brake Rollers and Wheels
Type 80 brake rollers are compatible with load conveying rollers of any diameter and should protrude approximately 2 mm above the conveyor roller bed. They control the speed of packages on gravity lanes, maintaining a constant conveying speed.

Motor Drum Rollers
Motor drum rollers are compact, allowing for narrow belt conveyors while maintaining high torque. They are supplied with an IP 66 seal and rustless casing, suitable for the food industry.

Installation Guidelines
Motor drum rollers are for horizontal mounting only. When mounted on metal supports, a 0.3-0.5 mm allowance is needed between key beds and support slots. The drum cannot operate without a belt, and belt tension should be minimal to prevent sliding.

Available Options
Options include friction belt lining, rubber mounting supports, capacitors for single-phase motors, and drum idlers of the same size and shape. Special executions are available upon request.
