Furnace Blower Belts, Pulleys & Bearings
Belt-drive blowers use a belt, pulleys, and shaft bearings to turn the squirrel cage, and they are still common in older and larger furnaces. Belts stretch and glaze, and bearings dry out — both are inexpensive parts that cause expensive-sounding noises.
174 blower belts, pulleys & bearings in stock, ready for same-day pickup at our Coquitlam warehouse or shipped worldwide. Homeowners and contractors buy at the same counter — no trade account needed.
Signs your belts & pulley may have failed
- Squealing on startup, or a rhythmic chirp while running
- Visible cracking, glazing, or fraying on the belt
- Reduced airflow with the motor running normally
- Rumbling or grinding from the blower bearings

Belts & Pulleys questions
- How do I find the right belt?
- The size is printed on the belt itself — for example 4L360 or A36. If the old belt is unreadable, measure the outside circumference and the width, or give us your furnace model number.
- How tight should the belt be?
- About half to three-quarters of an inch of deflection at the midpoint under moderate thumb pressure. Over-tightening is the most common installation error and destroys the motor and blower bearings.
