XPB V-Belts – High-Performance Wedge Belts for Industrial Power Transmission

Upgrade your machinery with premium XPB belts, engineered for high-strength, reliable, and energy-efficient performance. At Bolton Engineering Products Ltd (BEP Ltd), we provide a complete selection of XPB section wedge belts suitable for heavy duty applications, variable speeds and harsh industrial use.

Ideal for automotive applications, construction equipment and industrial power transmission, our XPB belts are engineered to deliver exceptional performance across all operating conditions – in terms of chemical resistance, heat resistance and other important operational factors benefiting from a long service life.

What Is an XPB Belt?

An XPB belt is a narrow wedge V-belt with notched inner construction for improved flexibility, cooling, and grip. XPB belts are part of the X-section (cogged) wedge belt family, offering higher efficiency compared to classical V-belts.

Key Characteristics

• Cogged inner profile for flexibility
• Higher power capacity in compact drives
• Excellent heat and abrasion resistance
• Reduced slippage under heavy load
• Longer belt life and lower energy consumption

Benefits of XPB V-Belts

• Superior grip for high-torque transmission
• Enhanced belt flexibility reduces bending stress
• Reliable performance at high speeds & variable loads
• Resistant to oil, heat, deformation, and wear
• Ideal for compact drive systems needing higher efficiency
• Low maintenance and long operational life

XPB belts offer improved performance over traditional wedge belts, especially in harsh working conditions.

Common Applications of XPB Belts

Our XPB section V-belts are used across multiple industries, including:

• Automotive engines & alternator drives
• Trucks, buses & heavy vehicles
• Construction machinery
• Compressors & blowers
• Conveyor systems
• Industrial pumps
• Agricultural equipment
• HVAC systems
• Power transmission for industrial machinery

Their robust construction makes them suitable for continuous-duty and heavy-load operation.

How to Choose the Right XPB Belt

Selecting the correct XPB wedge belt ensures optimal performance and extended system life.

1. Measure the Belt Length

• Measure the inner circumference using a flexible measuring tape.
• Avoid steel rulers or metal tapes—they distort belt shape.
• After looping the tape around the belt, straighten it to obtain accurate length.

2. Measure Belt Width & Height

XPB belts have a trapezoidal cross-section with notched teeth on the inner side.
To identify the correct size:

• Measure the top width of the belt
• Measure the belt height (thickness)

3. Match with Pulley Specifications

Check pulley labeling for:

• XPB section
• Required length (e.g., XPB1600, XPB1700)

4. Consider Load & Operating Speed

XPB belts are ideal for:

• High-speed operations
• Variable load environments
• Heavy-duty torque transfer
• XPB Belt Size Reference

Frequently Asked Questions (FAQs)

1. What makes an XPB belt different?

XPB belts are cogged wedge belts designed for higher flexibility, better cooling, and improved grip compared to conventional V-belts.

2. Are XPB belts suitable for high-speed drives?

Yes. Their construction supports high-speed, high-torque applications with minimal slippage.

3. How do I measure an XPB belt?

Measure the inner circumference, top width, and height using a flexible tape—never a steel ruler.

4. How long do XPB belts last?

When correctly aligned and tensioned, XPB belts provide long service life and reduced maintenance needs.
