Get it right the first time—optimize your belt life, system performance, and uptime.
Installing and maintaining a V-belt isn’t just about fitting it on the pulleys. It’s about maximizing belt lifespan, reducing downtime, and ensuring safety. At AIMS Industrial, we support your process with easy-to-understand guides that make belt maintenance easier and more accurate than ever.
How Do I Install a V-Belt Properly?
- Power off all equipment and ensure its locked out.
- Fit the belt over the pulley grooves—do not force or stretch it.
- Adjust pulley positions to allow proper belt fit.
- Tension the belt according to spec (see next section).
PRO TIP: Use a Belt Tension Tester to get accurate results every time.
Choose from our:
-
Single barrel tester (15kg) – ideal for individual belts
-
Double barrel tester (30kg) – perfect for joined or multiple belts
Both options are designed to measure belt tension accurately during installation or routine maintenance, helping extend belt life and minimise downtime.
How Do I Tension a V-Belt?
- Use a tension gauge or follow the manufacturer’s deflection recommendations.
- Too loose = slippage.
- Too tight = bearing wear.
How Often Should V-Belts Be Inspected?
Check belts as part of your routine maintenance schedule—ideally:
- Monthly for high-use or industrial applications
- Quarterly for moderate-use machines
Look for cracks, fraying, misalignment, or stretching.
What Causes V-Belt Slippage?
- Incorrect tension
- Worn or dirty pulleys
- Oil or grease contamination
- Excessive wear or age
How Do I Prevent V-Belt Misalignment?
- Use a straightedge, laser alignment tool, or pulley alignment app.
- Misaligned belts cause heat buildup, uneven wear, and energy loss.
What Are the Signs of V-Belt Wear or Failure?
Replace the belt if you see:
- Cracks or splits
- Glazing or shine
- Squealing noises
- Frayed edges
- Belt slipping or jumping
Don’t wait until failure—proactive replacement saves cost and downtime.
How Do I Replace a V-Belt?
- Power off and lockout the system.
- Loosen the tensioner or move pulleys to release the belt.
- Remove the worn belt and inspect pulleys for damage.
- Install the new belt, ensuring no twists or forceful stretching.
- Tension and align using proper tools or manufacturer specs.
Can I Use Multiple V-Belts on the Same Drive?
Yes—and no need to match if you're using high-tolerance belts like Gates.
They stretch slightly in use, compensating for minor length differences.
But with Aramid/Kevlar belts, matching is essential—they don’t stretch at all.
Tip: Always replace all belts in a set together. Mixing old and new leads to uneven wear and reduced lifespan.
Do V-Belts Require Lubrication?
No. Never lubricate a V-belt. Keep belts and pulleys:
- Clean
- Dry
- Free from oil, grease, and debris
Contaminants reduce grip, increase slippage, and deteriorate belt material.
