V Belt Pulley FAQ - Expert Purchasing Guidance

Q1: How do I determine the correct V belt pulley size for my application?

A: Three critical measurements are required:

Pitch Diameter (PD): Measure where belts ride in grooves
Bore Size: Shaft diameter with proper clearance fit
Groove Profile: Match belt section (A/B/C/D or 3V/5V/8V)
Raydafon provides free sizing assistance with CAD drawings.

Q2: What maintenance extends V belt pulley service life?

A: Implement these best practices:

Monthly Inspections: Check for groove glazing/wear
Proper Tensioning: Use tension gauges (avoid over-tightening)
Alignment Checks: Maximum 0.5° angular misalignment
Our pulleys include wear indicators for easy monitoring.

Q3: Can you supply pulleys matching obsolete equipment specifications?

A: Raydafon specializes in legacy system support:

Reverse engineering from samples
Pattern recreation for discontinued models
Material upgrades to improve original designs
Submit drawings/photos for immediate feasibility analysis.
