Wheel alignment is one of the most critical factors for
optimal performance from your bandsaw.
Heat, vibration, wandering, blade wear, tire wear and
overall bandsaw wear are considerably decreased when
the wheels are properly aligned or “coplanar.”
Coplanar wheels automatically track the blade by balanc-
ing it on the crown of the wheel. This is known as copla-
nar tracking.
