Technical Review: BANDO BANFLEXSCRUM Wide Angle Belt 2-11MS1180 3-11MS1180 4-11MS1180 - Selection Guide & Specs
Share
Overview: Solving High-Speed Vibration Challenges
The BANDO BANFLEXSCRUM Wide Angle Belt represents a breakthrough solution for industrial facilities struggling with vibration, noise, and power transmission inefficiencies in high-speed machinery. This specialized V-Belt system addresses the critical pain point of excessive vibration that plagues conventional power transmission systems operating at speeds up to 60 m/s. The unique 60° wedge angle design provides superior load distribution and reduced stress concentration, making it ideal for applications where smooth, quiet operation is non-negotiable.
Available in three configurations (2-11MS1180, 3-11MS1180, and 4-11MS1180), these banded polyurethane belts feature a construction that combines polyester tensile members with polyurethane compression sections. This engineering approach delivers exceptional performance in demanding industrial environments, from textile machinery and packaging equipment to high-speed manufacturing lines where precision and reliability are paramount.
Technical Specifications Analysis
The BANFLEXSCRUM series represents BANDO's premium solution for high-speed power transmission challenges. The technical specifications reveal why this belt outperforms traditional power transmission components in demanding applications:
| Specification | 2-11MS1180 | 3-11MS1180 | 4-11MS1180 | Common Features |
|---|---|---|---|---|
| Number of Ribs | 2 | 3 | 4 | 11MS Profile |
| Outside Length | 1180 mm | 1180 mm | 1180 mm | ±0.5% tolerance |
| Top Width | 24.4 mm | 24.4 mm | 24.4 mm | Standard 11MS section |
| Thickness | 7 mm | 7 mm | 7 mm | Polyurethane construction |
| Wedge Angle | 60° (wide angle) | Uniform load distribution | ||
| Minimum Pulley Diameter | 63 mm | Optimized for high-speed operation | ||
| Temperature Range | -30°C to +60°C | Industrial environment capable | ||
| Maximum Belt Speed | Up to 60 m/s | High-speed transmission | ||
| Tensile Members | Polyester cord with large tensile strength | Minimal flex fatigue & elongation | ||
| Compression Section | Polyurethane with tie band | Enhanced durability & flexibility | ||
The 60° wide angle design is particularly significant - it provides approximately 50% more sidewall support compared to standard 40° V-belts. This engineering feature translates to better load distribution, reduced stress concentrations, and significantly lower vibration levels. The polyester cord construction ensures minimal permanent elongation, maintaining consistent performance over the belt's service life.
Buying Considerations: Selection Guide for Industrial Applications
When selecting the appropriate BANFLEXSCRUM belt for your application, consider these critical factors:
1. Rib Count Selection: The number of ribs (2, 3, or 4) determines the power transmission capacity. For light-duty applications or where space is limited, the 2-11MS1180 provides adequate power transmission. The 3-11MS1180 offers balanced performance for most industrial applications, while the 4-11MS1180 delivers maximum power transmission capacity for heavy-duty machinery.
2. Load Rating & Application Matching: Evaluate your machinery's power requirements, torque characteristics, and operational speed. The BANFLEXSCRUM series excels in applications requiring smooth operation at speeds up to 60 m/s. Consider the specific demands of your equipment - whether it's textile machinery, packaging equipment, or high-speed manufacturing lines.
3. Environmental Compatibility: With an operational temperature range of -30°C to +60°C, these belts are suitable for most industrial environments. However, consider exposure to oils, chemicals, or extreme conditions that might require additional protective measures or alternative industrial belting solutions.
4. Pulley Compatibility: Ensure your pulley system accommodates the 63 mm minimum diameter requirement and is designed for 60° wedge angle belts. Mismatched pulley angles can significantly reduce belt life and performance.
5. Maintenance Considerations: The polyurethane construction offers excellent resistance to wear and minimal maintenance requirements. However, proper tensioning and alignment remain critical for optimal performance and longevity.
Frequently Asked Questions
Q1: What makes the 60° wedge angle superior to standard V-belts?
The 60° wide angle provides approximately 50% more sidewall support compared to standard 40° V-belts. This design distributes loads more uniformly across the belt's cross-section, reducing stress concentrations, minimizing vibration, and extending service life. The wider angle also allows for better cord support from sidewalls, making it ideal for high-speed applications up to 60 m/s.
Q2: How do I determine which rib count (2, 3, or 4) I need for my application?
Rib count selection depends on your power transmission requirements. The 2-rib version (2-11MS1180) is suitable for light-duty applications or where space constraints exist. The 3-rib version (3-11MS1180) provides balanced performance for most industrial machinery. The 4-rib version (4-11MS1180) offers maximum power transmission capacity for heavy-duty applications. Consider consulting with a power transmission expert or reviewing your equipment manufacturer's specifications for precise requirements.
Q3: Can BANFLEXSCRUM belts replace standard V-belts in existing systems?
While BANFLEXSCRUM belts offer superior performance, they require compatible 60° wedge angle pulleys. They cannot directly replace standard 40° V-belts without pulley modification. However, when upgrading existing systems, the performance benefits - including reduced vibration, quieter operation, and higher speed capabilities - often justify the investment in compatible pulley systems. Always verify pulley compatibility before installation.
