FAQ
How does excessive belt tension affect the bearings?
Excessive radial force puts high loads on the bearings, leading to overheating and premature failure. The correct tension is specified by the belt manufacturer.
Do you ship pulleys from stock?
The stock level is shown above the price and may vary depending on the warehouse.
What materials do you use for pulleys?
C45 steel provides high mechanical strength and fatigue resistance - the right choice for heavily loaded drives with frequent torque peaks.
Does shaft runout damage pulleys?
Yes - shaft runout causes cyclic jerking of the belt, which leads to cracking of the pulley hub and accelerated belt wear. Before mounting the pulley, it is worth checking the shaft runout with a dial indicator.
